Hi, I was wondering if you could write something for yandere!alpha!sanzu?
I could see a scenario where reader meets him and just assumes he's this pretty, sweet, and quiet alpha but then realizes he's kinda crazy as time goes on. Reader sees his katana, learns he's involved with a gang, and is also pretty sure he's stalking them. But he's just so sweet, picking reader up with his car, helping them clean, and is surprisingly very clingy

note 2 (for anon) : I really hope I didn't stray too much from your original request... feel free to send another request if that's not what you had in mind! and sorry for the long wait!!
MY MASTERLIST: ★
your first encounter had been nothing sort of special, quite ordinary actually. however, he quickly stood out from others with his soft speech and calm appearance.
sanzu was supposedly a friend of a friend that your colleague had invited to one of her small party. knowing that, you warmed up to him quite easily. you exchanged a few words, sanzu keeping the conversation alive quite well, his natural eloquence making it hard for you to part ways at the end of the party.
sanzu didn't seem aggressive nor demanding, he kept a very polite stare, even offering his jacket with a sweet smile after your first date when he saw other alphas eyeing your cleavage.
he took care of you very gently, listening to your rambling attentively and complimenting any slight change about you nobody would've noticed. his scent felt reassuring, both manly and gentle, the type of smell that makes you want to burry your nose in his neck.
sanzu was definitely a good alpha in every way possible.
and so you kept the dates going, discovering more of his sweet side. you liked how he never pressured you into doing anything, letting you decide where you'd be hanging out today. sanzu made it clear that what mattered was your happiness, what you wanted to do.
he surprised you with flowers, enjoying how happy you looked.
but, somehow, you could feel him grow more and more protective as the days went by.
it started subtly : a gentle hand on the small of your back when another alpha walked too close, a sudden shift in his tone when you mentioned hanging out with coworkers he hadn’t met. he never said anything harsh, never raised his voice. but something in his gaze felt heavier now, lingering a bit too long, too harsh for you.
you chalked it up to affection. maybe even instincts. you knew alphas could get territorial, and sanzu had made his love for you quite clear, so it had to be just that, right?
but then came the morning you found a small scratch on your apartment door. thin, fresh, and definitely not accidental. you tried to brush it off, but your omega instincts prickled. you knew something was off.
that same day, sanzu showed up unannounced at your workplace. he claimed he was in the area and wanted to bring you lunch. he smiled, kissed your forehead, and you smiled back, even as your stomach slightly twisted.
“you work too hard,” he whispered, brushing a stray hair from your face. “i just want to take care of you.”
if course, you thought it was sweet. maybe a little weird, but that was the sanzu you fell in love with, and your doubts didn't feel legitimate enough for you.
and then you saw the katana.
it wasn't even by accident. it was carefully placed in his car when he came to pick you up one night. you laughed nervously, asking if it was for cosplay or something. but sanzu just smiled, wanting to but failing at reassuring you.
“nah,” he said, voice light. “just a keepsake.”
and that's all you were given as an answer, he didn’t elaborate and left you in such a relentless state you struggled to keep your scent in check.
after that, you started noticing more things, how he always knew where you’d be, how he texted when you were walking home even though you hadn’t told him you were leaving. how, once, you found his scent on one of your clothes even though you hadn’t worn it in days.
you wanted to ask. you really wanted to know. but something about the way he touched your cheek, so soft and gentle, made the questions stay stucked in your throat.
besides… he was still the same sanzu, right?
he still remembered how you liked your tea. he still laughed at your jokes, cleaned your kitchen without being asked, and held you so close you felt safer than anyone could ever imagine.
so what if he got a little possessive ? alphas were like that, right ? it was only natural and not worthy of worrying your mind. besides, you were born a tiny bit anxious and an overthinker, maybe it was time for you to fully rely on him and stop those useless thoughts ?
but the feeling never left you. the feeling that something more sinister was hidden beneath his smile.

so you waited until he was asleep.
his arms had been wrapped tight around you all night, like he was trying to press you into his ribs where no one else could touch you. his scent clung to your sheets, warm and dizzying, almost invasive. you’d spent hours staring at the ceiling, heart beating too loudly to ignore it.
so when his breathing finally evened out, when his grip softened just enough and you knew he was asleep, you slipped out from beneath him.
your phone was already in your hand. you had thought about it for a long time. just one message. something as simple as that.
“hey, i think we need a bit of space. just a little. i need to clear my head.” you wrote, biting the nail of your thumb.
you didn’t send it right away. instead, you just stared at it for a moment, thumb hovering over it. you knew it would hurt him, that was for sure. but wasn't it healthy? for the both of you? you wouldn't be gone for long, just enough time to help you think clearly about everything.
so finally, you hit send. turned off your phone, and exhaled a shaky breath, trying hard for sanzu not to notice the change in your scent and how on edge it has been.
you didn’t hear him move, nor did you hear him wake up, it was complete silence. but suddenly, he was right behind you.
his voice was quiet, but sharp and sent a shiver down your spine.
“space?”
you froze.
“you want space from me?”
when you turned to look at him, his eyes were wide, not angry, not exactly. more like… shocked. like the world had collapsed under his feet and he couldn’t understand why.
“baby, i thought you were happy,” he said, stepping closer, his hand reaching for your face. “you said you were happy.”
“i am,” you whispered. “i just—i need some time. just a day or two. for myself.” you couldn't meet his eyes, hands getting a bit shaky by the second.
his lips parted and he let out a soft, almost sad laugh. “a day or two? alone? no, no, no—y/n, you don’t understand how dangerous that is. there are people out there who’d hurt you. people who’d take you away from me.”
you swallowed thickly and called him weakly, “sanzu…”
“no,” he said, and this time, it was final. “you don’t need space. you need me.”
he stepped even closer. his scent flooding your senses. it was heavy, cloying, you couldn’t escape it and your knees weakened beneath it. maybe he did it on purpose. maybe he always had...
then his hands cupped your face, gentle but firm.
“i’ve taken care of you,” he whispered, brushing his thumb over your cheek. “i did everything for you, made sure you never missed anything. i gave you everything even when you didn’t ask me to, did you notice that? i watched you sleep last night, you looked so peaceful...”
and that's when your blood turned cold, and without even knowing, your pheromones turned sour too, circling around him almost like a punishment. a painful reminder of what his obsession turned your relationship into.
“don’t push me away,” he said, almost pleadingly now, shaking slightly.
he kissed your forehead like he always did, it was slow, deliberate, like he was trying to shut your thoughts for good.
however, no matter what, his hands never gripped too tightly. his tone never rose. but everything about him was final, like he was choosing the words that would end the conversation for good.
“you don’t need to overthink things, sweetheart,” sanzu said gently, brushing your hair behind your ear. “i know the world gets rough sometimes. but when that happens, you come to me. okay?”
you didn't answer immediately. instead, you closed your eyes, breathed in his heavy scent, powerful enough to cloud your mind for a moment.
you heard him soothe you, voice soft, trying hard to appear less threatening. you knew he did it on purpose, to confuse you. he was kind and he was worried, it was nothing more. but as usual, you were too stubborn to realise.
sanzu would never be mean to you. he'd simply help you understand that he wants the best for you.
“hey,” he whispered, tilting your chin up so your eyes met his. his expression was soft, painfully soft, like you were a wounded animal and he was the one nursing you back to health. “i’m not mad. i’d never be mad at you. you’re just… scared. that’s all.”
he wrapped his arms around you, pulling you in close. you could feel the hum of his chest, the way his scent deepened, it was comforting, safe and overwhelming in a way that made it hard to think. your instincts soothed under it even as your mind screamed.
“you’re tired,” he said, swaying the both of you slightly like you were a baby in need of comfort. “you always get this way when you’re tired. i’ll run you a bath, yeah? something warm."
his voice was thick with love, and pride. as if he had done something worthy of your praise.
and he had, hadn’t he? he took care of you. remembered things you forgot. loved you in ways no one else ever had...
he loosened his hold only to gently guide you toward the bathroom.
“just let me handle things,” he added softly, brushing his thumb over your lower lip. “you don’t have to think. you don’t have to decide. i’ll always know what’s best for you.”
