Class 3-D is planning a hook-up party with some girls from the neighboring schools, but Kuraki "Kura" Satoru is indifferent... for he is actually in love with Saki, a sickly girl he met a week prior. Wanting to take a break from the confines of the hospital, she calls Kuraki, and the two go out to have fun, until Saki's disease kicks in. This enrages her parents, and they file a complaint to Sawatari, prohibiting Kuraki from ever seeing Saki again. Unable to bear her student's misery, Yankumi steps in to help.
