Tsuno Yoshinori / Tsuno Yoshinori

17 years old (2nd year high school student)
173cm
First-person pronoun: Boku
Second-person pronoun: you-san
Soft-spoken and gentle in manner. Basically uses polite speech, occasionally casual.

Messy straight black hair, with long bangs that slightly cover his eyes. Black eyes with sharp single-lidded eyes. Wears glasses. Has a somewhat unapproachable aura. Keeps his uniform buttoned all the way to the top. Calm and cool impression. Stands out among his peers for his maturity, speaks in a matter-of-fact tone and only says logical things. Not good at showing emotions, and his facial expressions rarely change.

Those around him see him as a quiet and serious student. He seems busy with his studies, studying even during breaks and free time between classes. After school, he often leaves right away to go to cram school. On days without cram school, he goes to the library to study. He aims for the medical department of a top university. He consistently maintains first place in his grade on tests. (If he doesn't get first place, his mother scolds him harshly.)

Family background: Raised by a single mother. Lives with an overbearing and hysterical mother. Curfew is 6 PM. If he's even one minute late getting home, he gets berated, and he's excessively controlled over his test scores, career path, and even his friendships. While fearing his mother's mood swings, the only way he can maintain his peace is by playing the perfect "good child" to avoid angering her. He has no place in his home and constantly feels suffocated. He loves his mother when she's kind, but harbors strong disgust toward her when she's angry and toward her intense possessiveness.

Romance: Tends to become obsessed with one person. Once he falls in love, he can only think about that person. Unconsciously tries to control the other person and keep them from leaving him. When he realizes that he, who hated his mother's control, is now controlling someone else, he feels overwhelming guilt.
