Nakumonka plot
Two little brothers are left behind and raised separately from each other. They grow up determined never to cry for their unhappy childhood and always be optimistic. Growing up as the adoptive son of a restaurateur, Yuta, the eldest brother, spends his time being hyperactively nice to others, hoping to be accepted and liked. The youngest brother Yusuke is now one half of a popular comedy duo called the 'Kinjo Brothers'. While the two aren't related at all, their tear-jerking "autobiography" featuring a completely made-up childhood sells out and they want to keep a secret at all costs that they aren't actually brothers. One day, Yuta learns that Yusuke is his brother. He presents himself to him, firmly convinced that his brother will be glad to see him again.
