When dayoung got hit it looked like it hurt. Bad. But its fine. Accidents happen. I personally have a nephew and 3 nieces to look after sometimes. And when I do, I tend to accidentally hit them because they move about so much. It happens. Its part and parcel of taking care of kids. But at the end of the day, I apologize to my little nephew and nieces and they still love me. I hope fans can do the same to lee joon. He apologized and dayoung still loves him so please. Move on.
