I'm thinking.... he is a high- school student and bought a sofa because that one was 'dirty', and in the end he can invest a lot of money. Of course this means he is rich but why he did this?? I think he had a crush for director Kang. I think he may have feelings for director. And the way of approaching him is by bullying him about his age . I think there is more behind him hitting Yiyoung.
