Min Seok and Soo ho are the best characters on the series. I knew Jun Han from One spring Night and he was the reason why I saw this drama. I started with one oppa, now I have two haha Both are GREAT characters and BIGEST ACTORS. But Seung-eon (Chae-A) is no slouch either. I really love her. I guess all the characters on here ar good in some point. All except for Ji Hyun (Ju Hyun) she is THE WORST I ever seen. And the actrees? She is bad too. (I knew her from Weightlifting Fairy Kim Bok Joo and she did it bad too) One of the worst after Kim Goeun. Her performance is horrible, her character IS PATHETIC. I HATE HER (Ji Hyun, not the actress). I only want Ji Hyun dies, she want to look like a justice-protector BUT SHE ISN'T. The acting of "I'm super bad, be scared of me" IS A FUCKING JOKE!? Even my puppy is more dangerous that her. She made a lot of bad over inocent people. [spoiler]Suddendly she loves Soo Ho? She made his life MISERABLE. And now she cry? now she is regret? BUT IS FUCKING LATE.[/spoiler]
