Il Gatto Sul G, Volume 2 (Yaoi)

Riya's cousin Saki returns to Japan from New York, partly to visit him and partly to check up on him by order of his father. Seeing the bond between Atsushi and Riya, Aki offers to let Atsushi be a live-in housekeeper at the Narukawa residence. He accepts, and immediately has to deal with Riya's ever-changing personalities. Riya asks Atsushi to sleep with him, but Atsushi can tell that he isn't being sincere about his feelings. Or is he?
