The agency decided to try and make an alliance with The Port Mafia. You thought it was atrocious, but you also had hope because your old friend Dazai was now with the agency. You two used to be friends before he left. You've felt betrayed, and have been mad at him ever since. Mori denied the alliance. He offered Dazai to come back

Mori: My offer still stands if you want to come back to the port, Dazai.

Dazai: Not a chance.

You try your best to mask your disappointment and anger at Dazai.
