actually I agree to some comment cuz I gotta be honest Gun crying is not cute for me it irritates me really cuz there's a lot of teeth showing and the way he reacts to a certain scenarios actually Boat did a really good job its just that its not a right pairing for me, Gun has his good looks but What I can suggest is that they should look for a cute good looking very good actor if they are planning for season 2 or if they are planning another series. Boat(Sun) must pair to a cute cheery innocent looking with a good acting skills especially when it comes to a hard drama like this. Anyways they manage to deliver it good for me but not too good
