The Naksung Fam is a Union affiliated gang made up of five members, including Naksung Yoon, who is the designated leader of this group.
Overview[]
The Naksung Fam is considered to be very strong, and back in middle school they were the only five that could stand against Jake Ji. Despite this, there was never any hard tension between the two because Jake Ji didn't enjoy conflict and the group didn't get into physical altercations.
While the Naksung Fam set out and expanded their influence, many people believed Jake Ji couldn't stand against the five. It's true however, that Jake Ji cannot take on all of the Naksung Fam members at once, so Jake Ji decided to beat Naksung only, and later, all of his underlings submitted without violence.
The Naksung Fam has a 'private' affiliation to Donald Na and the Union, not as Jake Ji's colleague or underling, but as a completely separated representative from Daehyeon High. However, since he's not the official number one of Daehyeon High, Naksung isn't joining the table when the Union has a meeting. They mostly do the "dirty work" for Donald Na, as Naksung Yoon described it in Chapter 126.
Fighting Abilities[]
Although it was rumored in middle school that Jake wouldn't be able to handle all five members at once in a fight, it is revealed in Episode 239 that Naksung is not a great fighter. Naksung was attempting to hide during the Han River Fight, but he ended up bumping into Helmet who had also intended to hide. It can be assumed from this that Naksung Fam aren't great fighters, at least not individually.
