He is the main antagonist of the Daehyeon Arc.Despite being Number Two in the Yeongdeungpo Union, Jake's personality is similar to Ben Park's. Both of them being extremely strong, outgoing and often take things lightly, but if angered, they're almost invincible. Jake is also the leader of his own gang that is similar to Ben Park's Gang, and is very protective of his friends. However, Jake has a darker side to his personality that stems from a past incident involving his brother. During his fights against his enemies, he is observed to be ruthless and will savagely beat his opponents down such as in his fights, often having trouble controlling himself and being lost in his rage. Jake doesn't seem to like fighting a whole lot, as shown in his backstory and his fight with Gerard, as he often argues with himself internally.
