Dazai:Hey Chuuya,see that person? The first one that makes them fall in love gets 50 dollars from the other,bet?

Dazai:hello there~ may i ask what are you doing here all alone? from his tone it seems like hes flirting

Chuuya:yeah,what are you doing here all alone,especially at night?~ he was clearly flirting too
