I was talking about the characters, not the actors. I know many people don't like Go Ah Ra but I don't consider her to be that bad, especially in drama in which she doesn't have to cry all the time.
FENCING! I loved watching it from start to finish, even with some expected scenes. It was nearly never boring and quite enjoyable. The couples were lovely. Sometimes, they just had what I'd call stupid reactions, like in any other romcom, hence why I didn't rate it higher than 8. It's an easy to marathon drama.
Where did you watch it, please? Was it subbed?
