On the other hand, at home, he is a normal father, raising his 17-year-old daughter Junko (played by Yumi Kawai) alone and taking care of her daughter's bad behavior.Recently, Junko is very concerned about the time of Ichiro's return, worried that he will bring a man to her house to have sex with him.

One day, Ichiro was taking the bus home while smoking as usual, and ended up dozing off.

When Ichiro wakes up, he sees a high school girl boarding the bus wearing a skirt with her panties exposed and noodles hanging from her ears.Ichiro notices something off about his appearance and points it out, but the passengers argue, saying Ichiro is the one smoking in the car.Ichiro got out of the car as if he was running away, but what he saw was a different scenery, with people wearing strange clothes he had never seen before.

He finally found a familiar coffee shop. Before he could fully understand the situation, Ichiro became angry and drank the beer of Inujima Nagisa (played by Naka Risa) on the counter without permission, and the two had a dispute..
