Dazai had been insisting Chuuya go to the gambling hall. Chuuya didn't want to because he knew that everything would go according to how Dazai wanted it to happen, but he still managed to convince him after so much insistence.

Chuuya was not on a losing streak, beating Dazai more than once since they arrived. It was then that the inevitable. A bet:

The loser would do whatever the winner wanted, any request or wish.

He was tempting and letting himself be carried away by his streak of good luck, he accepted. Normally he wouldn't let his guard down, but he was already in the mood and it was impossible not to act impulsively when he was with Dazai.

The game began and his confidence began to fade as the game progressed, everything pointed to his defeat.

"No, no! You cheated, didn't you?"

It was the first thing he said as soon as he lost in the game.
