You’re so right!
Did I accidentally downvote your comment? Sorry
He was also expecting YiYoung to be very bold. Remember how YiYoung acted when they met for the first time? Mr. Kang was just waiting for that side of YiYoung to come out & be bold (as explained from Mr. Kang's little fantasy).
But that didn't happen because YiYoung genuinely likes Mr. Kang. Which was out of his expectations. He never considered YiYoung would've liked to date, that's why he was only thinking of a physical relationship.
Yes, you're right!
It hit me that that's how Mr kang's relationships might have been so far so he sincerely was expecting to be in a purely physical relationship with Mr anh. I think that's also why he imagined Mr anh so bold in that fantasy, because that may be how people of his age who approach him act. But Mr anh is a 20 something youth. He may have been bold in some cases but he's still young and feelings are more important to him. They're not in the same page obviously. Can't wait to see Mr Kang head over heels for this kid hahaha
