Naoto Watari

Naoto Watari is a second-year high school student whose life was upended after losing both parents, leaving him and his younger sister to live under their aunt's roof. Dedicating himself entirely to his sister's well-being, he became known around campus as a devoted "sister-obsessed" student, while also taking on duties as a beautification committee member. The quiet routine he had built for himself is shattered when his childhood friend—someone who once left deep emotional scars on him—transfers into his school, forcing him to confront the shadows of his past and become entangled in a complicated web of intertwining feelings.
