Even after it was revealed why Yeo Reum dumped him i don't fell bad for her . She should have been honest with him and trusted him to be there for her. He would have got it since his own mother is terrible too. All she did was bring back painful memories for him.
I thought the confession would be Hyeon O . It seems like they cut down his role in the show because the trailers made it seem like it would be a love square.
