You gotta hand it to the old man, he knows how to be evil and bring out the evil out of people
I wonder if this is the dude that was thirsty for MC's mom and he will become a nuisance
The public members of the school gang gets forcibly 'recruited' into the big street gang. And MC has no intention of entering the criminal underworld.
So he lets the rapist's son and Mr. Glasses play gangsters, and pull the strings as their puppet master. Both accept because they don't have the chops to be the leader themselves, and both respected MC from the fight, and both hated Tae.
