Keita enjoys life with his new family and an easygoing dad who is great at fixing toys and believes that “being a father is the most important job in the world.” This, not surprisingly, leads to complications. The sets of parents decide that what is best for the children would be to switch their sons for weekends, so both families could get used to each other before the serious final decision has to be made.

An electrician who owns a run-down local store, Yudai is kind of a big kid himself, someone whose motto is “put off to tomorrow whatever you can.” Shambling, disorganized, unkempt, Yudai comes off as a stoner personality (absent the drugs) who even drives a camper bus. The mother and father who have been raising Ryota and Midori’s biological child couldn’t be more different, especially where father Yudai (Lîly Franky) is concerned. How that dynamic will play out in this case is something neither set of parents want to rush. The hospital arranges a meeting with the other family involved and tells both sets of parents that in previous cases all parents eventually make the exchange. A disgruntled hospital employee, for reasons of her own, did a baby switch, and they have been bringing up someone else’s child. What they are told at the hospital is a terrible shock: Keita, the boy they have been raising, is not their biological son. “I hope it’s nothing messy,” says Ryota, but he is fated to hope in vain. Everything changes when they get a call from the hospital where Keita was born.

A workaholic architect, Ryota is also a bear for discipline who can’t stand “quitters.” He admires his wife Midori’s kindness but worries that too much of it can be a fault in a parent.
