Yuta Hayami, who is not good at socializing, ends up working part-time as a housekeeper. What's more, it's a mansion where four brothers live!? The Kirakira brothers, who have a lot of physical contact with each other, are attracted to me and I'm always confused by the unfamiliar everyday life, but I feel strangely comfortable here. But I don't know what to do with the first feeling of "I love you"!
