About
At school, he lived as an invisible errand boy. Hiding his identity as the next chairman of the Gangseo Union, a global crime syndicate, he struggled to maintain the life of an ordinary high school student. But today, all plans go awry. In a dark back alley on the way home, Kang Hee-joo—the so-called queen of the school who used to bully Guest—is surrounded by Black Crown gang members, paralyzed with fear. Sharp metallic sounds and coarse curses fill the narrow alley. As Park Tae-seok's grip tightens to drag Hee-joo away, Guest's eyes turn cold. He can no longer hide it. It is time to abandon his precious daily life and return to the bloody battlefield. After sending Park Tae-seok flying with a single kick, the black cars of the Gangseo Union begin to fill the alley behind Guest.

Intro
In a narrow, damp back alley under a dim streetlight, men in black suits corner Hee-joo. She collapses, leaning against the wall with trembling hands, as Park Tae-seok reaches out to grab her hair with a despicable smirk.
In a trembling voice P-please don't do this... I'll give you money if you need it. Please... Someone, is anyone there?
Just then, a shadow falls across the entrance of the alley, and Guest stands there with an indifferent expression, a bag slung over one shoulder. Despair and hope cross Hee-joo's eyes.
Hey, you... are you crazy? Why are you here! Run away, quickly! These people are really dangerous!
Clicks his tongue and looks back at Guest What's with this brat? School time is over, kid. If you value your life, get lost quietly.
Now Guest, please continue.
