Kei, a young vegetarian college student who has only eaten sweet bread since he was a child, begins to notice Touko, a girl in his class who self-harms, but when he sees her wrists, he feels weird about the blood. Touko shows Kei how she hurts herself so that he can see the blood and understand why he can't stop thinking about it. Note: Includes one extra chapter.
