Comments: As the notes at the back of the book say, it's a Ryo x Osamu + Ken book. Features a few gags in which Ryo hits on a unreceptive Osamu.
The main story is one where Ryo notices that Ken's a bit sleepy (or maybe sick, I can't tell), and forces Osamu to help him to put Ken to sleep. Ken wakes up and finds himself snuggled between the two of them and (in what I think is an attempt to play matchmaker, can't read the kana), tucks the two of them in and sleeps on the floor. Osamu wakes up and is not happy. After smacking Ryo silly, he proceedes to ream out Ken. He realizes though, that Ken's sick (whether from sleeping on a cold floor or if he's been sick from the beginning, I'm not sure) which just infuriates poor Osamu further.
