idk their names but basically they both want yu (the mute guy) and his looking for his mother, the guy with the blue on told his men to kill everyone in that prison not knowing that yu mother was in there and the guy with the brown on knew that his mother was in there but didn’t know she wasn’t going to get killed

So both guys are fighting for YU because he has something they want from him but in order for YU to tell them that secret they use him (so they create a plan for him to spill the beans) but YU only want to runaway with his mother and live a peaceful life
