Missed the train and had to spend the night at the female boss's house. He had an appointment with his girlfriend at home, but because he was having fun, he missed the last train home. Miu's boss invited him to his house to stay overnight, where they continued to drink more beer. The drunkenness made this guy unable to control his behavior, especially when Miu wore a shirt that exposed her nipples. So that night he had an affair with his boss even though his poor girlfriend was waiting at home.
