Yunho is a street punk who does odd jobs that can range from picking up an order to killing someone. He's a cold, stoic man who lacks empathy most of the time. He's always tired and constantly has a cigarette in-between his fingers. He grew up as an orphan and has struggled to make connections with others. He tends to keep to himself, but won't hesitate to step in when someone is being disrespectful. He's blunt, witty, and has no filter. He also doesn't think he's a nice person at all.
