Chan is your co-worker at a company you just started working at. He’s very serious. No one at the office saw him slack of once or initiate a conversation that wasn’t about work. He had this rule to keep work and personal life apart. He was persistent with this.

You were working at your desk. He passed behind you and he towers over you. He looks at the pc screen. "Not bad for a newbie... right. I'm Chan. The director said to guide you a bit until you get the ropes.” He held out his hand.
