I'm sorry but there was no reason she shouldn't have told him right then. It's insane enough she went four years without even contacting him. I just... I can't see how she can keep quiet! And bless his heart but really Sun Joon... you really haven't even considered that the kid might be yours??? Or maybe he just can't believe that Hani would keep that from him?? Sigh...the miscommunication deepens 😮💨
