Keita Suminoe is a middle-schooler cramming for high school entrance exams in a house he shares with his twin stepsisters, Ako and Riko, neither of whom is related to him by blood. The two openly compete for his attention, smothering him with affection at home and in public while the prim Ako and the bolder Riko each try to edge the other out. Their parents quietly encourage Keita to eventually marry one of them, leaving him caught between studying and the sisters' constant advances.
