A new request for a 'rental father' from Murata (Kankuro Miyato) to his unemployed brothers, Ichiji (Kanji Furutachi) and Niji (Kenichi Takitō), is to pretend to be a relative and attend the wedding ceremony! While my younger brother came to mind when I could eat and drink for free and get money, my brother was suspicious of the groom who rented his relatives. Moreover, the bride, Temari (Yukino Kishii) has a new life in her stomach ... A wedding full of suspicions. The useless brothers stand up to save Temari and the baby from the groom!

The unemployed brothers, Ichiji (Kanji Furutachi) and Niji (Kenichi Takitō), are once again requested to 'rental father'! This request started with an interview with her client, Kanako Higuchi, saying that it would be a little long-term, but she says, 'The world will end in three months.' Ichiji feels distrustful of Sumiko, who treats her brother as if she were a slave, but she is overjoyed that she can make a lot of money. What is the true request of Sumiko, who has many mysteries?
