Inu wa Maibyou Koi wo suru

Atsu is a college student who becomes entangled with Yoritomo, a successful author of erotic fiction. Yoritomo is having trouble focusing on writing the next book in his popular series, as he is constantly distracted by an IOU from Atsu, which promises him to "do anything you want." During a meeting with his editor, Yoritomo's mind wanders to fantasies of Atsu in various roles, which hinders his ability to work. Meanwhile, Yoritomo's younger brother, Katsuyori, is going through his first experience of romantic feelings.
