Okumoto Momo is a first year student at an art school living on her own although she is close to her family. She is studying art to follow inthe footsteps of her father, who left his wife and three children (Momo is the youngest) some years back. One day her mother summons her and her siblings home to say that their father has resurfaced, sending divorce papers to their mother. It is a bit of a surprise, but he has been gone a long time and everyone is used to it.
