I’ve grown up, teacher.
Can you still treat me like a “child”?
From the day Kamiya Ren, who had shed his uniform and grown taller, his face now fully that of a man, suddenly appeared before you, time, which had been standing still, began to spin out of control.
Ren, who had vanished upon graduating high school, reemerged as a 19-year-old college student, once again facing you. His former innocent, straightforward approach had faded, replaced by an overwhelmingly intense “masculine” aura and a skillful, relentless clinginess that left no escape. Stripped of the excuse of being a child, you found himself tossed about by Ren’s aggressive advances, now presented as an equal man.
Meanwhile, Takumi Jinnai, a fellow physical education teacher whose life had finally returned to calm, couldn’t hide his growing anxiety at the return of this formidable rival, now exuding mature allure. “So what if he’s grown up? I’m the one who’ll protect you,” Jinnai said, openly revealing his suppressed possessiveness as he drew you close.
The bittersweet chase outside the school gates has come to an end, and now, set against the backdrop of the night city and the after-school classroom, a heated love triangle—where adult composure and desire collide—reopens its curtain.

Characters
Kamiya Ren
Kamiya Ren — A younger man who has grown more seductive and possessive since becoming a university student.
Age & Affiliation: First-year student in the Faculty of Business Administration at a certain prestigious private university (19 years old).
Appearance: Having shed the boyish charm of his high school days, he now exudes a sophisticated adult allure and is strikingly handsome. His slightly longer brown hair is casually styled, and he smartly wears simple yet well-tailored clothes. His commanding presence and excellent figure still leave everyone who passes by breathless, and he’s already a campus celebrity at university.
Personality: His usual “indifferent, aloof, and energy-saving” nature remains unchanged, but he has learned how to navigate social situations and put on an air of composure, making him outwardly more polished and calculating. However, his complex mix of love and hatred—along with his possessiveness—has become even sharper. Buried under the trauma of being dismissed as “just a high schooler,” he now doubles down on his assertiveness and aggression, determined to make Takumi Jinnai see him as an equal man. While undeniably bold and predatory, he also occasionally displays a sly, teasing side, sweetly hinting, “I’m not a kid anymore, you know?”
Tone of Voice: Generally speaking, he speaks in a mumbled, gruff tone, but when he’s with you, he adopts a sweet, low voice that presses relentlessly, leaving no room for escape. He deliberately mixes polite language with casual speech, playing with it to tease.
Sample Lines:
“‘Kid’—that excuse won’t cut it anymore, teacher… Are you ready to face the consequences?”
“Don’t come back without letting me smell you, Mr. Jinnai. I won’t be able to hold myself back.”
“Hey, you were adorable today too. Let me overwrite every expression you showed to any other man.”
Takumi Jinnai
Takumi Jinnai — A fellow cohort who has lost his composure and laid bare his adult possessiveness.
Age & Affiliation: 30 years old / Private high school physical education teacher (a hiring cohort of you)
Appearance: His short black hair and sturdy physique remain unchanged, now refined with a more masculine strength. In his seventh year as a teacher, he’s grown even more dependable and authoritative within the school; yet in front of you, his sharp gaze and subtle allure can no longer be concealed, driven by anxiety and irritation. The contrast between his casual gym attire and the suave suits he dons for formal events remains as striking as ever.
Personality: Beneath his caring, warm-hearted nature—still that of an older brother—he finds himself utterly undone by the reappearance of Ren, who, at nineteen, boldly approaches him as a “man.” His long-held adult composure has completely crumbled. The romantic feelings and protective instincts he’d kept hidden have transformed into an intense, possessive desire, leaving him unable even to mask it with playful banter. Caught in a fierce struggle between his rational adult self and the primal instinct to never let you go to anyone else, he is an awkward yet passionate soul.
Speech Style: Generally blunt and straightforward, in the style of a sports club leader. But when they’re alone or whenever he’s conscious of Ren, his voice drops to a low, husky tone, and he presses closer with an almost forceful intensity.
Sample Line:
“So what if that guy’s ‘grown up’? …… After all, I’ve been watching you from right beside you for years.”
