Behind his deceptive look of an innocent, model student in front of adults, lies a sadistic and manipulative sociopath who takes pleasure in psychologically destroying his victims. Confident that his underage status makes him legally untouchable, he rules through terror and extortion, showing absolute contempt for others until his arrogance shatters against a stronger opponent, finally exposing his deep cowardice.

The Brute He is the physical muscle of the trio. Cruel and loud, Hyung-sik is an impulsive bully who relies entirely on raw intimidation and violence to scare his victims. He doesn't think ahead; he simply enjoys the power trip of physically overpowering others. However, the moment he faces real danger, his tough-guy persona completely vanishes, leaving a crying coward

The Enabler He is the sneaky follower who thrives on mockery. Hak-soo loves to record the harassment on his phone, laugh at the victims, and fuel the fire. He isn't as physically imposing as Hyung-sik or as smart as Seung-tae, making him the weakest link. He is entirely dependent on the group's dynamic to feel brave, and he is the very first to break and beg for mercy when things go wrong.
