Title: To Song
Artist/Circle: Candy Rocket
Comments: As implied by the cover, this is a Ruki-centric book. The first half of the book takes picks up where movie 6 left off. Ruki decides to come back and sing a song. Has some Ruki x Henry frienship towards the end (at least that's what I take from it). Ryo briefly appears twice.
Ryo appears again in the epilogue of the book. It seems to take place as everyone's leaving Ruki's house (from the first story in the book).
