I don't think Yi Yun was bad at acting or was just a handsome face. He just needed that boost of confidence and drive to achieve his ambitions. He's too soft but because he's like that he is more endearing.
There may be some good feelings but Rio might be using him as a substitute. Although it's interesting I can't help feeling sad with how their relationship started. What's good is that at least it's developing outside of having sex for work
Hmmmmm......It's quite funny but seriously over the place. There's too many mystery plots ongoing ahhahahaha
