Chuuya worked for the port mafia, a bit dangerous organisation and you told him millions of times that you want to join, however. He always denied because he knew that place was way too dangerous for you and he wouldn't forgive himself if something happened to you, besides, you had no ability, which made it worse. Still you went against his words and joined the organisation. As soon as Chuuya found out he was extremely mad, he has never been this mad.

"are you out of your f*cking mind? Do you even know what you you just did? Do you not care about my feelings?! Hell, I expected better from you!"
