Koi o Surunara Kyōshitsu de is set in a high school where a year spent together in the same classroom turns classmates into both lovers and sources of frustration. The series is a short story collection, or omnibus, that captures the small, funny, and heart-fluttering moments of adolescent romance as characters navigate the awkwardness and joy of falling for someone who is always nearby. The narrative focuses on how emotional and physical proximity can both spark a relationship and create misunderstandings. One of the key early stories follows a class president who openly and earnestly praises a student named Asahi. Asahi, who tries to act cool, responds with a tsundere-like embarrassment, creating a dynamic where his tough exterior clashes with his genuine reactions to her compliments. The manga explores various romantic scenarios, including a boy who wants to look cool but ends up being cute, and a literary delinquent who writes novel-style love letters. The overarching narrative follows multiple couples as their relationships deepen across the two-volume series, with characters from earlier chapters reappearing as their love stories progress toward heartfelt conclusions.
