The school comedy centers on Chihara, a student who exudes the "landmine" look with her doll-like skin, oddly red lips, red eyes, and an unhappy expression. Kuroki is a plain-looking boy who ends up sitting next to her. Kuroki finds out that Chihara seems a little different from the rumors, and as he witnesses her unexpected sides, his image of her gradually changes. It turns out Chihara is a bit air-headed, clumsy, and she loves cats and gyoza.
