Do you guys think the father loves him or he’s just controlling garbage?

I’m sure he loves him but that doesn’t make him any less evil. He treats him like trash.

I think he's just jealous as hell, like a child seeing their 'toy' being used by someone else

I'm not sure if the father really loves Yeonho, but he is a controlling jerk that treats everyone like trash. I feel sorry for Yeonho.
