He runs his fingers through your hair. The scabs are from getting hit in the head hard enough to bleed but not enough to bleed through your hair so no one would have noticed you were injured if you didn't tell anyone.
The idea is that you got hurt and decided it wasn't important enough to tell your boyfriend even though head injuries can be really dangerous.
You were hurt and either didn't think your pain was important enough to address or thought he wasn't safe enough to go to for help.
I think that uncertainty would be a fun flavor of angst to play with.
cw: fluff, angst if you squint, dark humour, slight suggestive at fyodor
first time writing bsd characters(except that dazai oneshot)
✧ OSAMU DAZAI
Dazai probably wouldn’t say anything at first. His elegant fingers would linger just a moment longer over your injuries, catching even the slightest of your reactions. Sometimes you read together, and you hadn’t realized his habit of stroking your hair would eventually give you away.
He’d catch you off guard that day, at a moment you weren’t expecting—with sarcasm and a glint of playfulness in his eyes.
“Didn’t know I finally found someone to commit double suicide with.”
Your eyes widened as you processed the meaning, scrambling for a justification, but he cut you off, cornering you with that quiet yet overwhelming presence. His usual smirk remained, but it was laced with gravity.
“Don’t ever hide things like that from me again.”

✧ CHUUYA NAKAHARA
You and Chuuya share a tumultuous relationship. You often get on each other’s nerves, but the love is equally intense. Loyal, protective, yet at times too volatile—hence the frequent quarrels.
A deadly combination.
Now that he knows you, he couldn’t truly live without you anymore. Technically, he could, but he would rather not risk being alone again.
From the very beginning, he disagreed with you going on a mission solo. But after relentless persuasion on your part, he relented. He didn’t want you to think he doubted your competence.
You had barely stepped through the door when he started inspecting you, head to toe.
“Chuuya, what the fuck, man?!”
“Shut up.”
You tried to shove him away, but eventually just sighed and let him work. His touch was delicate, almost reverent like he didn’t want to find anything, yet couldn’t stand the thought of you being in pain.
Betrayal. That’s what he felt.
“Really, Y/N?”
He turned away sharply, tossing his leather jacket onto the bed and marching toward the medical kit.
“Chuuya, it wasn’t that bad! You didn’t expect me not to fight back?”
“I knew you shouldn’t have gone alone! I don’t understand why they keep assigning you without me!”
“CHUUYA!”
A tear brimmed in your eye and that fierce look in his gaze dissolved, softening into guilt and sorrow. He came to you, pulling you into a quiet embrace, speaking against your hair.
“I’m sorry, baby. I just…”
You knew his mind had spun out with worst-case scenarios. You knew he was scared of what the future might hold.
“I know.”
“Let me take care of you.”
“Sure, mrs. doctor.”
You smirked at him, and he returned it, guiding you gently to sit so he could tend to your wounds.
✧ FYODOR DOSTOEVSKY
Fyodor already knew you were hiding something the moment you returned from the mission he sent you on. He trusts your abilities—he wouldn’t have risked your life otherwise. You’re one of the few people whose life he’d place above his own objectives.
So when he handed you a glass of wine after thoroughly thanking you for your efforts, he deliberately avoided touching the wounds on your head when he slowly stroked your hair, suspecting they were something you wouldn’t admit.
He knows you’re strong, and he knows you wouldn’t easily betray yourself. But your breathing had become too steady, your body language too rehearsed.
“My love, it seems these missions agree with you too much, no?”
You laughed. Barely. There wasn’t much to deflect with yet.
“Well, when I know what’s waiting for me at home… what do you think?”
You were clever enough not to look him in the eyes, but his fingers gently tilted your chin upward. His false smile mirrored your own.
“Why wouldn’t I spoil my loyal and transparent partner?”
Your grin faltered. You hated when he caught you like this.
“How long have you known?”
He raised an eyebrow.
“Since then?” You nearly rolled your eyes. “Of course. I didn’t hide it. It wasn’t serious. That idiot just—”
His grip tightened slightly.
“Try again.”
Those hypnotic eyes made you swallow hard.
“I won’t hide anything ever again.”
“Good girl.”

✧ RANPO EDOGAWA
Despite his brilliance, Ranpo acts like a spoiled child at times. He was already annoyed after you sent him to the store three times today. He loathes routine errands.
His boredom evaporated, though, when he noticed your odd behavior after returning homeș the way you exited the bathroom in a mild panic, like you’d been caught doing something. You had been: disinfecting your wounds before he could see them. But he didn’t know that. Not yet.
Your behavior was out of character, far too open for someone trying to hide something. Normally, he’d never need to use his “ability” on you. But this time, he was far too intrigued.
“Y/N?”
“Yes, baby?”
Your voice trembled slightly as you tried to breeze past him, but he caught your hand and looked at you.
“Nothing.”
He started tickling you as a distraction, until you were gasping with laughter, trying to push him off.
You smelled like disinfectant.
That night, while you braided your hair before bed—your usual routine—he asked,
“Want me to do it?”
“Ha-ha, funny Ranpo.”
“I’m serious, baby. My last ounce of energy is for you!”
“Lazy ass. No thanks.”
“Really????”
His exaggerated whining made you roll your eyes.
“Okay, fine!”
He pretended to understand what he was doing, braiding gently until his fingers started brushing areas they shouldn’t have. You suddenly seized his hand. Your eyes locked.
“You did this on purpose. All day.”
“Bingo.”
His eyes were deadly serious. You weren’t used to that from him. With others, he minded his own business, but with you? Clearly not.
“I’m sorry, baby…”
He nodded once in forgiveness. And then, finally, you told him everything—and promised it wouldn’t happen again.

✧ SAKUNOSUKE ODA
Oda is a gentle, empathetic man with a strong sense of justice. So you can imagine how he reacted mentally the moment his hand brushed your injury while gently stroking your hair. He’s the kind of lover who evaluates a situation from every angle before speaking. When his touch stilled and his eyes widened, fixed on you, you knew you’d slipped up.
“Oda, baby, I can explain—”
“Please do.”
He’d be disappointed in your decision to hide it, but he wouldn’t hold it against you for long. Still, he wouldn’t want a repeat. You loved him too much to see that worried expression on his face again, or to watch him meticulously tend to every wound afterward, silently determined to restore what was missed.
⸻
✧ ANGO SAKAGUCHI
Ango often presents as calm and composed, but you know he’s far more intricate than the world sees and you love him for that. His true thoughts can be hard to decode at times.
He noticed your injuries in the morning but didn’t immediately address them. Instead, he brushed the hair from your face, revealing a hidden wound, likely not the only one.
Your sleepy voice stirred at his touch.
“Ango?”
He said nothing, waiting for you to fully wake. His expression gave away nothing, but the intensity in his gaze said everything.
“Morning, baby.”
He smiled, but it didn’t reach his eyes.
Eventually, later that day, you confessed. Cornered by that memory and his unrelenting stare. He knew your nature and didn’t blame you, but let’s just say a discreet tracker somehow ended up sewn into your clothes during your next mission.
⸻
✧ RYUUNOSUKE AKUTAGAWA
Despite his ruthless, detached exterior, Akutagawa masks a raw, emotionally charged core. He’s fiercely loyal, intensely protective, and entirely devoted to you. Expecially if he wasn't the one who got to protect you. He should've been the first of defense.
That doesn’t mean he wouldn’t be furious upon discovering you were hurt and hadn’t told him.
“What the fuck is this, Y/N?”
“I just hit my head, Akutagawa. It’s not that serious—”
“Do I look like an idiot to you? Is that what you take me for? Who did this to you?!”
⸻
✧ ATSUSHI NAKAJIMA
Atsushi is known for his altruism and his tendency to put others before himself—even at his own expense. Still, He’s a bit unsure of himself sometimes.
So imagine his panic when his fingers brushed against your hidden injuries.
He spoils you with so much affection that you tend to curl up in his arms and forget about the world’s problems. You swore under your breath, realizing you hadn’t concealed yourself well enough.
You knew what would follow. And maybe it would’ve been better not to hide it at all, because it only made things worse.
He leapt off the couch in a frenzy, completely derailed from the movie you were watching.
“Y/N?! What happened? When? Why didn’t you tell me?! Who did this?! Do you think I wouldn’t have been there?! What did I do wrong?!”

✧ DOPPO KUNIKIDA
Doppo is a disciplined, composed man. Stoic on the outside, renowned for his meticulous organization and strict adherence to routine, even in your day-to-day relationship. He likes to plan every shared moment and takes pride in easing your burdens. His love language is likely acts of service. Still, behind that rigor lies a profound affection. In truth, you might be the person he loves most in the world.
He’d feel immediately betrayed and also deeply guilty. It had been one of the rare days when you declined to bathe with him, knowing how much he cherished the routine of caring for you, washing your hair with tender precision. But when he later heard a quiet hiss escape your lips from a wound—albeit not open—it became clear you’d hidden something from him. That hurt. Deeply.
“I’m so sorry—Damn! I didn’t know! Why didn’t you tell me? Don’t you trust me? Am I not good enough for you?”
⸻
✧ YUKICHI FUKUZAWA
Similar to Doppo in many ways, he’s serious, composed, and rooted in discipline. He prioritizes the safety and well-being of those in his care, and remains level-headed even under pressure. Yet beneath that composure, there is warmth—and with you, a quiet devotion.
You are one of his life’s priorities.
He wouldn’t see it as a betrayal. He rarely assumes someone’s behavior is a reflection of him personallyș instead, he looks inward first.
He noticed something was off the moment you tried to redirect his hand when he reached to stroke your hair. You never do that.
“Is everything alright?”
“Yes, why wouldn’t it be?”
“Why would my wife feel the need to conceal something from me?”
He’s always given you space and respected your privacy—but your eyes betrayed you. The guilt was unmistakable.
You felt awful and apologized immediately, though he had already forgiven you the moment he saw the truth. He believes you when you say it won’t happen again.
⸻
✧ SIGMA
Sigma might appear confident and self-sufficient, someone who prefers working solo. But he harbors insecurities like anyone else, especially in relationships. Even though he knew it was selfish, his first thought was whether you didn’t trust him to protect you.
But the two of you knew each other too well. Many words weren’t always necessary to explain what the other needed the most to hear.
When his hand found the wounds on your scalp, he said nothing, waiting until you spoke.
“Baby, I didn’t tell you because I didn’t want to worry you. I know you would’ve protected me if you were there, but I handled it. You didn’t know, and that’s okay. I’m sorry I kept it from you. I won’t do it again.”
“It’s alright, my love. I understand you didn’t want to make me anxious. But it’s normal for me to worry because of how I feel about you. I’m just glad you know I’d protect you with everything I have. And I know you’d do the same.”
