Papa Henshuu Kiss Tokidoki Shitagokoro

Kaoru Yuzuki is a busy editor of a literary magazine. One day, he feels he has reached his limit in raising his two-year-old son, Minoru, by himself, and tells his assigned writer, Taiga Kuroiwa, of his intention to resign from his position. Taiga then offered to help him raise the child at his home on the condition that Kaoru continue to be in charge. Kaoru decides to accept Kuroiwa's offer, who says he has always wanted a family. Every time he returns home, he is greeted by Minoru's smiling face and Kuroiwa's slightly tongue-in-cheek and forceful kindness, and he wishes that these days could go on.

Just then, he realizes that Kuroiwa has been secretly stealing kisses from him in his sleep...?
