Maybe as you all know the-A-type Seohyun is famous for being timid, shy, and uncomfortable around boys. Especially when she has to do lover things, like skinship. I know its just a CF/MV, not real life. But if you really pay attention, this scene is only last less than 2 or 3 seconds. So, it didnt look like it was planned by the director. Seems like the mature magnae Chansung, who has a lot of experience with girls, managed to hold the-hard-to-get Seohyun hand!
