Idk how to put a spoiler warning so just spoilers down there

I think I roughly remember that gangster looking guy who worked for that old Chairman kidnapped his friend,the one who was acting as a mole, and Yoohan went to help him but he was also stabbed with a knife, that was about it, ah, while he was unconscious, he also saw his brother in his dreams telling him not to be stuck up on them anymore and let them die in peace or something-
I suck at explaining and I always forget the names- sorry

Buddy I think you replied to the wrong comment...
