Kazuma, who has no family, lives with Rito, his guardian. Rito is described by those around him as "perfect", but he doesn't wake up in the morning unless Kazuma wakes him up, and he leaves the housework to him. Kazuma, who loves Rito, is happy to spend his days taking care of him and is satisfied with their relationship as it is. However, when a beautiful colleague sends Rito home drunk, Kazuma feels threatened by the presence of another person who might have a grudge against Rito...? (Source: Comic Fleur, translated)
