After developing an unlikely friendship with the grouchy old woman who lives in his neighborhood, Hiroto suddenly finds himself inheriting not just her house but some rather difficult emotions as well. His 18-year-old cousin, Natsumi, moves in with him, but as a struggling art student, she has her own troubles to deal with and may just put Hiroto's easygoing lifestyle to the test.
