From the last parts of S1, they'd been so unfair with Sun Oh, got hung in the air without closure and being the unchosen one as his friend prioritizes love over friendship. The story becomes so unfair for Sun Oh, so I was hoping that he will get justice in S2 but instead they destroyed his character even more. In reality, how the story goes with him is so depressing from his family problems to the way that he has always been left by important people in his life and forcing himself to love someone that he doesn't. His one and only friend chose love over him even knowing that the girl cause so much pain to him by the way she left him hanging was just so unfair. It sounds so wrong. The storyline is just nuts and has no sense at all.

I don't have any issues with the acting. I think everyone portryed their role well.
