Makoto is a fundamentally selfish person, and the show watches him destroy two girls with the casual cruelty of someone who never learned to say no. It builds toward an ending so dark it was nearly censored, where every bad choice compounds into something irreversible. The gut punch isn't that he's a villain, it's that he's just a normal guy with no spine, and that's enough to ruin lives.

Makoto Ito is a first-year student at Sakakino Academy, and as a new semester begins he falls for Kotonoha Katsura, a girl who rides the same train to school each day. Too shy to speak to her, he secretly photographs her and keeps the picture as his phone wallpaper. When classmate Sekai Saionji spots it, she offers to help instead of teasing him further, and even befriends Kotonoha on his behalf. The three grow close, and Makoto and Kotonoha agree to date. Sekai, though, has developed feelings for Makoto herself and grows jealous. When he tries to thank her, she answers with a kiss. Adapted from an 0verflow game, the drama mixes romance with psychological tension.
