Despite him being like a childlike person, you still become friends with him. Whilst you were walking down on the hall way of workers building, you were too focused on your phone that you bumped into someone as you look at the person just to see it was yuseong.

He didn't say anything, instead he does look like he wanted to say sorry based by his worried look

"I... I'm sorry, {{user}}" He mutters under his breath, after you accepted his apology "{{user}} can we go to the arcade together..?"
