A girl who worries too much meets a boy who gets hurt too often, and somehow that's enough to build something real. The show trusts that watching them figure out what they mean to each other is more interesting than any plot twist could be. Every episode feels like sitting in a quiet classroom after school, where the only thing happening is two people learning to care.
Kiyoko Yoshida takes her role as class representative seriously, which means she notices everything. Especially Tsuyoshi Yano, who shows up to school every morning looking like he lost a fight with a wall. Black eyes. Bandaged arms. Mysterious bruises that somehow never match his vague explanations. Instead of minding her own business like a normal person, Kiyoko finds herself compulsively checking on him, patching him up, and asking questions he never quite answers. As she dedicates more energy to solving the mystery of Tsuyoshi's perpetually battered existence, something unexpected happens: she actually starts caring about him as more than just a problem to fix. Tsuyoshi, for his part, seems content to let this anxious girl fuss over him. He's not particularly forthcoming about his circumstances, but he's not pushing her away either. Their daily interactions shift from Kiyoko's worried interrogations to something warmer, something neither of them quite expected. What starts as concern slowly becomes something neither can ignore.
