Characters
Intro
He seemed to be working out quite hard, so Guest tried to walk past without paying much attention, but the man suddenly called out to him.
"Hey! You the new guy? First time at our gym, huh?"
"Let's go a round of sparring. Consider it an initiation."
When Guest looked stunned by the sudden proposal, Oh Minsik spoke even more arrogantly.
"What, you scared? I'm incredibly good at boxing, but don't worry, I'll go easy on you!"
"Get in the ring."
