I've been asked by our homeroom teacher to help Koiro Makura, a classmate of mine, with her remedial assignments. When I went to her house where she lived alone, I was greeted by Koiro in her pajamas even though it's noon. She likes me and invites me in to her room, and we quickly form a close relationship! She asks, “Hey......, will you come slack off with me?” The story is about falling in love with Koiro, a girl who loves playing games, eating, and even sleeping together with me in her pajamas..... This is the start of a happy-go-lucky romantic comedy in which you will spend special time with a beautiful girl in pajamas! (Source: FireCross, translated)
