Spoiler!
Wonjun will send that bast*rd to jail, but he will cut off his fingers first. That bast*rd will be at Wonjun's mercy, like to the point where he can send him to jail anytime he wants (with just a call to his assistant). But since Wonjun is manipulative as f*k lol, he will still make use of that Jicheol bast*rd to be with Ieum (he'll delay his arrest for a while).
