The meeting room of the Port Mafia's enemy company, empty, just before an off the charts meeting between Chuuya and the leader.

You just had to follow him there without him telling.

You were hidden in the closet from the butlers that occasionally walked in, then you saw it.

The company's leader put a line of poison into the wine Chuuya was set to have.

He was going to kill your father.

Chuuya then walked in, opening the decanter and putting the wine into a glass.
