Miyuki’s father is a gambler, his mother lives apart from them, and he’s close to being kicked out of school if anything goes wrong. However, he’s pretty happy with his life, being surrounded by his two older sisters and noisy friends.
On New Year’s day, when he and his sisters went to the shrine to make their wishes, their father jumped out from the shrine. He gleefully proclaimed that he was now divorced for good and the Yaegashi family is no more. Miyuki was shocked, but his sisters didn’t seem to mind at all. They both wanted him to live with them and he had until March to decide on who he wanted to go with.
