Ren Fujimaru appears to be the epitome of an accomplished actor, save for one minor flaw: he has trouble working alongside children owing to a past traumatic event. To remedy this issue, Ren's manager suggests that he should reside with his young co-star Yuu Kusaka, who happens to be his boss' offspring, for a week. Initially, Ren dismisses the notion as a jest, but he is taken aback when he realizes that his manager is serious. In order to enhance their working relationship, Yuu must lodge with him in his abode. However, Ren has never cohabitated with children before, and engaging in conversation with Yuu poses a significant challenge.
Thankfully, Yuu's manager, Kei Haruo, comes to the rescue. Kei, a former child actor whom Ren revered as a youngster, is now in close proximity to his long-time idol. Ren seizes the opportunity to inquire into Kei's disappearance from the limelight, but his request is denied.
Can these three individuals, each bearing their own burdens, experience significant transformations in the space of just one week?
