Still shocked by his mothers deathbed revelation, Takeru puts aside his anger and shame to grant her final wish. He agrees to allow Hyoju, the once-secret daughter of his fathers first relationship, to come live with them. But only-child Takeru has a lot to learn when it comes to making room for the newest member of his family. Hyoju, too, has lessons to learn: born and raised in a foreign land, she must begin to adjust to her new life in Japan and the brother she has never known.
