Former daddy VS Nishikido daddy !? A big pinch in the same house!

The man who suddenly appeared in front of Nishikido (Ryo Nishikido), Teppei Sakura (Takashi Tsukamoto), was a former Danna of Haruka (Yuka) and was the father of children!
Haruka and Mei (Umika Kawashima) are confused by the appearance of Teppei who had just left the house due to debt and affair, but Yuto (Yuki Imai) and Kana (Kanon Tani) seem to be happy.

Nishikido is jealous of Teppei, who has decided to stay with the Hanamura family until his work settles down.
Nishikido and Haruka remind Teppei that 'Idol Ryo Nishikido is married is a secret', but Teppei takes it in the wrong direction and begins to approach Nishikido.
Apparently Teppei also has a secret ...
