Oikawa

Oikawa is a middle-school classmate of Ayumi Otosaka in class 1-C, quietly smitten with her from the moment she transfers in. Calm and easygoing, he keeps his feelings low-key even after Ayumi turns him down, never quite letting go of his affection for her.

His attempts to get closer to her are repeatedly foiled by Ayumi's protective best friend Nomura, while back at home, classmate Konishi — hopelessly infatuated with Oikawa herself — grows increasingly resentful of the attention he pays to Ayumi, a rivalry that eventually spirals into something far more dangerous than typical schoolyard jealousy.
