I'm seriously disappointed about Sungah, reacting like that... as always... seriously, Joonwoo has to be honest and scream, get angry, and tell his POV in front of Sungah...
Cmon, acting like a criminal ? Who was there to help you behind ? Who was there to solve your social problems ? Jeez... cmon MC, just say what you have done for her, once and for all. And again, joonwoo gonna forgive her...
