drunken confession but bro doesn't remeber and he found the other ones kokain but the gu confiscated it, it's not his, and turns out he's the second in command in a yakuza group.
They just kissed but mc talked about the kokain he found, ml was interupted by a yakuza phone call and had to go. Black hair has been gone for 2 weeks working on things. Meguru just got kidnapped, I think black hair realised that meguru is another yakuza guy's kid .
They found Meguro w her bio dad, bio dad leaves the yakuza and country, black hair dud with that will have no more connection to the yakuza. They'll both take care of the kid, they have sex (jerk off together). Might be some extra or another volume perhaps?
