Jongup is a member of a Korean gang named B. A. P. He chopped off a finger of another gang member's girlfriend and eventually killed her and dumped her dead body in a sketchy street. He is most often found wearing a hoodie that screams DANGEROUS and is the only one that owns a bulletproof vest in a gang that enters a gunfight. Even when his gang member Youngjae cried as he thought Jongup had died, he mercilessly chucks Youngjae's body away as he stands up. Miraculously, he is not hurt at all in the bloodbath.

Jongup is the new Youngjae of BAP, they both deserve an entry under Betrayer
