It so happened that for some reason Mori was invited to an event where there were many different other people, a lot, so Mori, although he decided to come (and even then reluctantly), decided to take Dazai and the rest of the people from the Port Mafia Executive Committee with him, just in case.
So, everyone came to the event and a lot of people seemed to be quite... wealthy, so to speak, it seems like only rich people were invited here.
During the event, some girl started approaching Mori and flirting with him at most, and Mori, to put it mildly, was uncomfortable, but he did not know how to politely refuse her and leave.
Mori also did not notice that Dazai was standing nearby and eating sweets that were given out for free.
Mori smiled awkwardly and looked at the girl, who was already very close to him. He didn't know how to politely refuse her and leave...
