a/n : As they say, without unnecessary stupid chatter ā just in Saeās style?
This differs quite a bit in tone from the excerpt/sketch (small, but there is a difference) compared to Michael.
[Reader-insert: An ordinary working man.]
Headcanon! Yandere Sae Itoshi.
He didn't 'lose his mind.' He chose this state consciously. It's his method, not an illness. It's his decision.
Quiet, intellectual, controlling (subtle/å·é
· ā "cold").
Deep rational yandere ("analyzing psychotype")
He does not destroy ā he rewrites you.
His love is not an impulse, but a decision: he chose you, as one chooses a path.
He studies you, predicts, models the reaction ā and subtly changes the reality around you so that you become dependent.
This is not just attachment. This is implantation.
Manipulator (emotional, behavioral, social control)
Stalker (knows where you are, who you are with, what you are thinking ā even before you)
Pseudo-guardian (does everything "out of love", even when depriving you of choice)
Evolving ā becomes more dangerous if he senses a loss of control.
Neurologist-empath: he reads emotions not empathically, but as a specialist ā and manages them.
Psycho-console: he turns you into a character in a simulation where you think you are free.
Behavior/Courting ā phase by phase:
He observes. Silently. For months. Studies words, reactions, your weak points.
You do not yet know that you interest him ā and he already knows where you will be in three months.
"You laughed when you were confused. I noticed that on the first day. And I decided ā you need someone to know you more deeply than you yourself."
He appears ā accidentally, "by coincidence".
He does not make the first move ā he leads you to the thought that you chose him.
He offers what you lack: stability, attention, comfort. You think it is your victory.
"You came up to me yourself. I merely responded. Or did I not?"
He becomes the center of your routine. Without him ā no breakfast, no sleep, no peace.
You begin to seek him yourself. And he ā is not always available.
Sometimes ā cold. Sometimes ā overly affectionate. It's a swing. You wait for his warmth ā like a drug addict for a dose.
"I am merely giving you what you seek. It is not my fault that you cannot stop."
skillfully prepares events and manipulations so that you yourself go into his hands, you yourself push someone aside besides him and you yourself encourage his obsession. he makes it so that in your eyes there remains no one except, of course, him. Other people, whom for some reason you do not reject, after just a couple of days disappear, and Itoshi then also makes you feel guilty for daring to look at someone other than him.
He eliminates alternatives ā a job, friends, stability.
You think you are free. But all paths bring you back to him.
How hard is it to escape him:
He doesn't keep you in a cage ā you yourself are afraid to leave.
He builds a reality where everything outside him is frighteningly empty, cold, unstable.
He knows your financial model: he can get you a job ā and control you through it.
He knows your routes, gets to know people in the shadows, creates conditions under which you return voluntarily.
If you leave ā he won't punish you immediately. He will let the world break you ā and then come to "save" you.
Not because he holds you ā but because he has become part of you.
He adapts to what you believe in to destroy it.
He doesn't trap ā he "helps" when you're on the edge, and you grab onto him yourself.
"You want to be free ā but first remember who held you when everyone turned away."
You won't recognize it as punishment ā until it's too late.
Gentle, morally devastating.
He doesn't shout ā he is silent, cold, detached.
He "disappears" for a day or two ā you begin to fear losing him.
He may delete numbers, erase your drafts, isolate access to social media, but do it so that you blame yourself.
"This is not punishment. This is your decision. I just deleted what makes you vulnerable."
In severe cases ā an emotional rupture after which you yourself ask for forgiveness.
He may "accidentally" mention your fear of loneliness.
He will make you feel what it's like to be without him.
He will shut off all his emotions ā and you will end up in perfect silence. And you'll be the one to ask for forgiveness.
Sometimes he will simply show you that he knows too much ā and you feel exposed.
"I'm not angry. I just recalculated how much you mean to me. In percentages. Don't worry, you're still in the plus."
How does he deal with opponents?
Silently and efficiently. No blood, no loud scenes.
Not physically ā socially and psychologically.
He sets people up professionally.
He enters their life unnoticed: Legally clean.
He destroys reputations, removes opportunities, makes it so that the opponent leaves on their own.
If someone is too persistent ā there may be an accident.
He destroys their authority ā with unnoticed conflicts.
The opponent either disappears, or gives you up himself, thinking that āyou'll be better with Saeā.
> "It's his own fault. He poked where he shouldn't have."
He squeezes them out psychologically ā so that the person disappears by themselves.
If necessary ā he causes an "accident". Without traces.
> "You didn't notice, but he no longer calls. He no longer exists in your life. And this is not a coincidence."
Does he need reciprocity?
It is desirable, but not obligatory. The main thing is your presence. He will do everything so that you don't leave. Even if you hate him ā he's there.
Not hysterical, not passionate. But a confirmation that you "belong" only to him ā mentally, emotionally, forever.
He creates conditions so that you not only return ā you become his choice.
Not in a romantic sense ā he needs your attention, dependence, fear of leaving.
You can be cold, you can be angry, but you must be near.
Love? He will call it "a necessity."
He does not demand the words "I love you" ā he watches how you choose him instead of sleep, work, friends, life.
If you do not respond ā he does not get angry. He restructures the situation so that you respond yourself.
> "You don't have to love me. Just... stay close. Forever."
He programs the "environment" around you.
He creates an environment where the rules are obvious without words:
Don't lie (he'll find out anyway)
Don't disappear without explanation (he will find you)
Don't get close to others (he will remove them)
He does not forbid ā he "convinces" that you yourself don't want it.
You yourself come to the necessary conclusions. He doesn't say "Don't talk to them".
You yourself lose interest in others.
...If you violate an "invisible rule" ā he doesn't punish. He changes behavior ā and you yourself feel that something has broken.
You ask to put everything back.
> "Rules? Do I set them? I just disappear when you forget who I am to you."
Contact with him is like poison with honey.
He is intimate, but not intrusive.
His touches are gentle, slow, precise.
He knows when you want hugs, even if you don't admit it.
He can be domineering if he sees you are weak. Or soft when you are panicking.
Physical intimacy is like an opium addiction: after it you can't think of anything except him.
> "You no longer look for others. After me ā you can't. No one feels like that."
He uses touches as an anchor: after a touch you lose the will to resist.
He doesn't take by force, but he can. You come to him yourself.
> "If you want ā I'll stay at a distance.
But you'll press yourself against me at night anyway."
For him closeness is even more power.
He does not seek passion ā he seeks control through closeness.
May be obsessively affectionate after one time, especially in moments of emotional instability.
> "I won't let you go. Even if you beg."
Danger on a scale of 1ā10
He doesn't kill. He replaces your personality with a version where you are his forever.
He doesn't intimidate ā he convinces you that without him you are nobody.
You fall in love. Then you lose yourself.
And then ā you don't want to get yourself back.
He will make you part of him.
And you yourself will call it love.
I used to think of myself as completely independent. Strong. In control. The world was my playing field. I always knew where and how to place my pieces. All I needed was clear logic and cold calculation. Emotions? They were a weakness I didnāt let myself be possessed by.
Not as someone important. No. You were⦠just background noise in my life that grew louder and louder. I wasnāt interested. I only watched. Your persistence. Your moments of weakness. And then one day you became part of my space.
I thought I could just control it. You were just another variable. I could manipulate it. I could adjust everything. But thenā¦
You became unbearably hard to ignore. You werenāt just someone in the background. You became the center. My life began to revolve around you, and I⦠didnāt know how to handle it.
You didnāt see me, right? You didnāt see how hard it became for me to pretend I didnāt feel everything that was happening between us. I tried to be cold, to keep my distance. But you came into my world, you changed it, and now everything is so familiar that I donāt even know where I end and you begin.
You think I donāt understand whatās happening? That I donāt see how everythingās slipping? Iām dependent. Yes. Iām not afraid to admit it. Because, after all, is that bad? When itās not only normal but stable? This is my stability. Iām dependent on you, and thatās not a mistake.
You donāt realize how you became my balance. You became what I expected, what I needed in my life. And every one of your looks, every one of your words now makes me stronger. I know how you think. I know what you want, and Iām ready to give you that. I hold you the way I need to. I understand that Iāve become⦠dependent. And thatās okay.
You keep thinking Iām holding you, but actually, itās you who holds me. I canāt imagine my day without you. Even if I wanted toāI canāt. And you know what? Thatās not a problem. Itās a decision. Itās my choice.
Now you are my life. My norm. Itās so steady that I donāt doubt it. I donāt want to change anything. I donāt want to be without you. You are my addiction, but what could be better? I wonāt save myself, and I donāt need saving. Weāre in this together. And that is peace.
I always knew I would control everything around me. But you taught me that true ownership isnāt staying outside. Itās being in. Being with. Being inside.
You are my norm. You are my stability. And I wonāt let you go.
Do you really think I don't know who I am?
I was born in a country where the word "yandere" long ago became a meme. Where girls with knives are avatars, where everyone jokes about the "cuckoo", and nobody believes it can be real.
They laugh. They make art. And then they disappear.
You think they're made up? No. I know what yandere are. I know how it looks from the outside.
You think I'm crazy? I'm simply consistent.
I read everything. From anime to court analyses. I know how their stories end. I know how they get caught, how correspondences are pulled up, how they find blood under nails. I saw photos of bodies. I listened to interrogations. I know the chemistry of decomposition, and how to hide the remains.
But the difference is that I'm not them.
I'm not weak. Not emotional. I'm cold-blooded. Calculated. I take a step only when I know three moves ahead where you will be.
They lost control. I did not. They killed out of jealousy. I make people disappear without a trace.
You won't find knives under my pillow. You will find the blanket you bought, from which your scent will never leave. You chose your cage yourself. You gave me the keys yourself. You became my stability. My variable. My system.
I do not lose control. I am control. I do not deny that I'm dependent. I admit it with pride. I built a system in which being near you is not obsession. It's the only way.
You feel it, right? That you no longer belong to yourself. That every step you take is already measured. You know that if you leave ā something will start to break. And it won't be me. It will be you.
Yes, I know who I am. I am the one who won't be caught. I am the one who holds you not with a chain, but with dependence. I am the one you invited yourself.
You didn't know? That a single glance in my direction is already a sentence. Now you know.
> "Violence, mania, stalking, murder ā and necessarily an end: blood on the floor and a camera in court. All these stories are the same. All these yandere are stupid. They get caught. They lose control. And they always lose the one for whom it all began. Ridiculous."
I knew this would be my reality long before I allowed myself to feel anything for you. In Japan such stories are everywhere ā online and in real life. Everyone watches, reads, mocks.
> "Another sick girl with a knife."
But I'm not them. I'm not emotional. I'm not unstable. I'm precise.
I will not lose you in rage, will not leave traces, will not allow myself to be exposed. I'm not "in love without brakes." I'm still ten steps ahead. But I am yandere. Consciously. Calculated. Surgically precise.
I don't make scenes. I don't grab your hand in public, don't whisper "you're mine" in a hysterical voice. I create a situation where you yourself decide to stay close. I choose where you'll end up, whom you'll talk to, what you'll lose to want to return. I don't keep you in a cage. I make you a person who no longer needs freedom.
You think I can snap? That someday I'll do something that gets me jailed? No. I'm too smart. In those stories ā yandere lose. But I write my own.
> "I read how they catch them. I watched how they fail. But I'm Sae Itoshi. I will not become a mistake in your life. I will become everything that's left in it."
Beginning ā You came up to him yourself. But it was his decision.
He did not approach first. He never takes the first step. He simply creates a space that you want to enter yourself.
You saw him at the gym. Then ā at the cafĆ©. Then ā at the bookstore. At first it seemed like mere coincidences. But he looked... beautifully careless. A smile ā as if it were only for you. You are one of hundreds, but he suddenly met your gaze and stayed in it a little longer than allowed.
You sent the first message in direct.
You invited him for ācoffeeā first.
You gave him your number first.
You did not know that all this ā were steps planned in advance.
You think you approached me first. You think you showed initiative. You were so confident: in that cafĆ©, with your phone in your hand, with headphones on. I deliberately chose that table ā a little closer than necessary. Deliberately opened the right book ā the one you recently searched for online. Yes, I knew. I saw your searches.
Everything looked accidental. You even laughed when you asked: āYou read this? Nice. Rare to meet someone with such taste.ā
I smiled. I said the name of the character you mentioned in your tweet a week ago. You decided it was a coincidence. But you were already in my net.
It was not luck. It was calculation. You were ready. You were vulnerable.
And I ā perfectly adapted to what you wanted to see.
From that moment everything went according to plan.
He seemed perfect. Not perfect like in made-up stories ā where the hero arrives and rescues. He was like a mechanic of an elite car: flawlessly assembled, gleaming, cold. Near him it became quiet inside.
Sae did not seek attention. Attention drew itself to him. And when you first noticed him ā you thought it was your choice. Naive.
You made a move. He turned. A slight smirk. He knew you would approach. Even then ā you were written into his equation. You did not yet know that at the very moment when you approached him first ā you opened the trap.
You began to notice oddities. He always appeared where you were. The same coffee. The same subway stations. Even the weather seemed synchronized ā rain when you were alone. Warmth ā when he was near.
Your posts on social networks received the same strange like, without a name. Missed calls from empty numbers. You laughed about it with friends: āA stalker, ha. Just like in games and visual novels.ā But each time after ā you caught his gaze in the crowd. He watched.
He knew you before you knew him.
You did not know that he had been watching for a long time.
Through mutual followers.
Through your GPS tags that you once carelessly left.
He knew where you studied. Where you work. Who your exes are. Who hurt you. Who attracts you. How much time you spend in a stuffy apartment and what songs you listen to when you are sad.
The address. The route home. Who you communicate with. Where you sleep. What you search for on the internet.
He knew what to say to make you open up. He gave you a shadow of safety ā as if you had chosen on your own. But all your choices were orchestrated.
You simply approached the bait.
Camera with muted sound. Monitor. On the screen ā you. Youāre coming back from work. You open the fridge. You donāt really have lunch again.
ā "Such a mess... Iāll have to clean up after him when he leaves again," Sae whispers to himself, slowly moving the mouse. Clicks. On the screen ā your conversation with a friend.
ā "What an idiot he is. Youāll realize it soon."
The next window ā an order: your favorite food. Sae clicks: ādeliver.ā Not from him. From a ārandomā courier. So youāll think itās a coincidence. So youāll smile. So youāll link the warmth in your chest ā to him, without even knowing it.
"Heās strangely often nearby. But Iām glad about it. His voice is so calm, his touches ā like innocent ones. I call it a coincidence. Heās just⦠always on time. Always at the right moment. Itās like he reads me."
You donāt understand that he truly ā reads. Every word of yours. Every breath.
He doesnāt rush. He waits until you come to him at night yourself. Until you ask to stay. Until you think youāre in control.
He doesnāt take by force. He arranges for you to give yourself.
You donāt decide anything yourself. He already knows who you spoke with, what your plans are, why you were late. He isnāt angry ā heās disappointed. And thatās worse. You feel guilty. You search for his gaze because it matters to you that he soften again. You stop making decisions yourself. Every āmay I?ā sounds quieter. Every āI just wanted to...ā is cut off.
Sae does not shout. He controls. He punishes ā with silence, isolation, sudden disappearance. You panic when you canāt find him. And he returns and says: āNow you know what it means to lose me.ā
Insert: Hidden camera / Audio diary
(sound of footsteps on wood, silence, then Saeās voice ā almost tender)
ā You know, I always knew when you lied. And I knew why. Not because you wanted to leave. But because you were afraid of how much you wanted to stay.
ā Do you still think you had a choice?
When you tried to leave ā you received letters. Forged. Old.
Messages from exes you long forgot. Supposed apologies. Invitations to meet. But as soon as you started replying ā everything fell apart. They didnāt remember the messages. They hadnāt written anything. And it all led you back to him.
Letters from family. Fake contracts. Even phony threats that Sae supposedly saved you from.
You began to doubt reality. But he was there. Always calm. Steady. āIām here. Everythingās under control.ā ā and you wanted to believe it.
You didnāt understand that trust ā was part of the construct. He kept you not in chains, but in need. You didnāt leave ā because it felt like you were staying by your own choice.
Sae Itoshi ā Audio Diary
[01:46 AM / Tokyo / Private log - encrypted]
(silence, click of the recording)
Today he tried to leave again.
I saw him check the train schedule. Hide his passport. Lie to me, looking me in the eyes.
I wonder⦠why does he think I donāt notice?
Iām not stupid. I only give him the illusion of choice.
(short pause, sound of breathing)
I am all he has. All he will have.
Today I deleted his coworkerās number. Erased the chats.
He thinks he lost his phone by accident.
He doesnāt understand that Iām protecting him. From others. From himself.
(sound of glass ā heās clearly pouring water)
On nights like this I want to keep him close. Tight.
So he feels ā I am here. I am everywhere.
Fear is a good feeling. Fear holds.
I used to think love was weakness.
And I will not let him disappear.
Not with anyone. Nowhere. Never.
I bought new locks. And replaced the cameras.
Tomorrow he will learn new rules.
(softly, almost tenderly)
He will learn to be only mine.
(click ā the recording stops)
Sae Itoshi ā Audio Diary
[03:27 AM / Tokyo / Private log - encrypted]
(muted breathing, as if just stepped out of the shower)
Not shouting. Not begging.
Just⦠sat on the floor and looked at me like Iām a monster.
I didnāt mean to make him hurt.
He chose himself. He decided to break the rules.
(soft finger taps on the table)
He dared to smile at someone else.
Not apologizing ā thatās already a challenge.
I locked him in a room for three hours. No light. No phone. No clock.
To make him think. To remember who he is and who heās with now.
He started banging on the door.
I didnāt open immediately.
But when I let him in ā he trembled.
Gently. Like a fragile doll.
He buried his face in my chest, wet with tears and fear.
ā I wonāt let you go. Never.
(sound of glass ā he sets down a glass)
Later I put him to bed. Stroked his hair.
Told him how much I need him. How empty it is without him.
I kissed his forehead as if forgiving.
Tomorrow he will say he loves me.
And then ā we will begin again.
(the recording slowly cuts off, faint hiss in the background ā like from a surveillance camera)
One day you ran away. A panic. A suitcase. A hotel room. A turnedāoff phone. Another city ā from Kanagawa to Saitama. You left. A real escape ā silently, with the last of your cash. He was asleep. Or pretending to be.
You turned into a different life: a small rented corner, an unfamiliar neighborhood, quiet streets. No one knows who you are, and that isāfor the first timeārelief.
Now I am not his. I am simply me.
The first night you slept fitfully. The second night worse. On the third you woke in a cold sweat from his voice ringing in your ears:
āWithout me you are nothing.ā
You deleted all contacts. But he was no longer in the phone ā he had settled in your thoughts.
You thought you were free.
Until the day you woke and found your favorite food in the hotel room. And the jacket you had lost in his apartment. And a note:
āYou knew I would find you. I donāt lose. I only return.ā
You screamed. But the room was paid for a month. Your documents had been updated. Someone had already filed an application for a new job for you ā your dream job. He had arranged a life for you. Without you. Without your permission.
And you were afraid. Because part of you⦠was glad.
ā Why does he make me feel guilty?
It wasnāt me who lied, who shut the door, who watched.
But why is there this residue inside me? As if everything is on me.
There is a heaviness in my chest. Pain in my throat.
I didnāt say a word, and he looked at me as if Iād betrayed him.
I only wanted to⦠breathe. To be myself.
But now ā Iām in the room he calls āours,ā with a lock that never clicks from the outside.
(Your attempt to leave. You said you wanted to go outside. Just to breathe. He was silent for a long time. Then he spoke.)
(his tone even, but something rotten in it)
ā After everything ā you want to go out? Alone?
(He steps closer. His eyes narrow. Heās not shouting ā and thatās scarier than a shout.)
ā I give you a roof, food, protection. I⦠gave everything up for you.
(He doesnāt blink. Standing very close. You feel the heat of his breath, but your body seems frozen with cold.)
ā And you still think you have the right to decide anything?
ā Itās not you who suffers.
ā Itās me who wakes up every day thinking ā what if you run away.
ā What if you lie again.
(He slams his hand on the table. The bang ā sharp, but not aimed at you.)
(a long pause ā and his voice becomes gentle. terrifically gentle.)
ā But if youāre so unhappyā¦
ā Leave and see who else will love you like this.
(He turns away. You see his shoulders tense. He seems to be holding a storm under his skin.)
ā Only later⦠donāt beg to come back.
(Silence. Only your breathing and his anger fill the air.)
You were silent. And he understood that he had won again. Not by force. Not by threat. By necessity.
You drank tea. From his mug. Lay under his blanket. In his apartment. With his scent. Everything felt like yours ā but it was his.
When did I stop being myself?
Every movement of yours is calculated. You knew he checks the browser. Reads notes. Knows when you go out and who you talk to.
But you no longer got angry. You eventually got used to itā¦
I donāt want him⦠But I canāt live without him. I donāt know how to breathe alone.
[03:27 AM / Tokyo / Private log - encrypted]
He left again. I gave him two days.
He didnāt eat. Didnāt sleep. Didnāt live. He only tried to prove to himself that heās free.
But freedom is an illusion when I give you everything. When you are dependent on my breathing.
He came back on his own. Silly, trembling. And I didnāt laugh. I simply opened the door. Offered a blanket. Sat nearby.
Now heās mine. Truly. Not because I hold him. Because he came himself.
You thought of leaving again. But when you reached for the doorknob ā a tremor seized your body. The world felt too loud. Too empty.
If I leave⦠who will give me a roof? Who knows that I like strawberry tea? Who will nurse me without asking?
You realized: youāre not just with him. Youāre in him. In the system he built.
He sat on the sofa and waited silently. No reproaches. No threats. Only presence. The pressure of silence. You turned back on your own. He didnāt get up. He only said:
ā Good. I knew you couldnāt do it.
[01:03 AM / Tokyo / Private log - final entry]
He sleeps. Nearby. His breathing even. Heās under my blanket again. In my rhythm.
Iām no longer afraid. He wonāt leave.
Because now ā heās not just mine. He is me. My meaning. My proof.
He utters my name in his sleep. Whispers how afraid he is of losing me. I won.
But I do not celebrate. I just⦠hold him tighter.
You hardly notice how youāve changed.
Friends are gone. They āfell awayā ā as if by themselves.
Your phone is always near, but you use it less and less.
Social networks ā scrubbed. Personal things ā erased.
Work ā remote, on his devices, through his contacts.
The apartment? ā no longer yours. He āhelpedā with the move.
And most of all ā you stopped resisting. Not because you donāt want to.
Simply⦠you no longer know how.
You are sitting on the floor, wrapped in his hoodie. You breathe heavily.
Sae enters without asking, without announcing himself. Sits beside you. Silent.
ā "I knew you wouldnāt leave," he whispers, running his fingers along your neck.
You tremble, but not from fear.
ā "Youāre happy, arenāt you?"
Even if inside ā there is emptiness. Even if the voice in your head screams that this is not you.
He kisses your temple. The camera in the corner blinks. It has always been on.
"Maybe if I had run away earlier⦠maybe if I hadnāt come over myselfā¦"
But you came. Yourself. And now ā even death seems less frightening than his absence.
š©¶ Iām sorry Iāve been away for so long. I didnāt expect it to take this long myself ā mostly I didnāt like how the sketch turned out; I wanted everything at once, and that was bad too. I donāt especially like this part. (It took so long that I already have other sketches in my drafts, but Iām not posting them because I need to release the headcanon first.) I hope I wonāt disappear for a long time again.
Poor English (Iām not a native English speaker, guys)
