Now what Jooin? What's wrong with your mom meeting Cain?

I don't think he thought it was wrong, it's more of being worried because he never told her someone is staying with him and judging by it. never told her about the guys in his life lol

Yes I understand that .. however it's not like Cain would tell the mother that he's jooin's bf (and he's not).. what I mean is I think he's a bit overreacting and I'm afraid he'll hurt Cain by saying something... At this point he's the one acting suspicious Infront of his mom
