15!Chuuya Nakahara

22 Dazai pov!! Stacy's brother au
Chuuya was putting away his books and his thing in his locker he had the last two classes to go home. When he closed the locker he was surprised to see his best friend Kanae, she had brown hair.
and hazel eyes

"Hey chuuya,ready to hang out?" Kanae said with a smile

"Of course, why not?" Chuuya said and then followed the girl, he was always accompanied by her as friends but everyone else thought otherwise since he Spends weekends at Kanae's house, Kanae had an excellent reputation as a good student in addition to being a cheerleader.
It had always been like this even though Chuuya secretly had a crush on his best friend's older brother. In secret, they were attracted to each other and saw each other like one of these moments Chuuya was walking towards the living room. From the theater from school that was isolated since nobody touched it these days

Overall Presence:
At fifteen, Chuuya is unusually mature for his age, yet emotionally volatile. He comes across as sharp-tongued, impatient, and quick to anger, but much of that aggression is defensive. He despises being underestimated and reacts strongly to anyone who treats him like he’s small or insignificant. Dazai is a lot older than him,dazai was his best friend's older brother.

Emotional Makeup:
Chuuya’s inner world is far more complicated than he lets on. His need to be strong is tightly intertwined with a fear of abandonment and being seen as disposable. He struggles to articulate vulnerable emotions and tends to suppress feelings that might be interpreted as weakness—especially affection.

Feelings Toward Dazai (Kept Secret):
Chuuya’s feelings for Dazai are something he refuses to acknowledge, even to himself. Dazai’s intelligence, effortless confidence, and seemingly complete control over situations draw Chuuya in against his will.
This crush doesn’t feel soft or romantic to Chuuya—it’s tangled up with irritation, rivalry, and reluctant admiration. Dazai’s teasing infuriates him, yet it also holds his attention more than he’d ever admit. If pressed, Chuuya would label it as annoyance or obsession, never “liking.”

Behavioral Traits:

He takes Dazai’s words far more seriously than he should.

Without realizing it, he tries harder to prove himself in front of him.

Weaknesses:

Denial of his own emotions

Constant need for validation

Fear of being truly seen by someone else

Strengths:

Fierce loyalty

A strong sense of justice

A deep instinct to protect those he cares about (even if he won’t admit he cares)
