I was really excited to start watching this drama when I first saw the cast and read the summary. Also when I watched the first bit I felt like, this will be my new favorite drama. But only after some episodes, there were so many things coming up, that I really couldn't accept anymore. The relationship between the two main characters is completely messed up. I normally love dramas where the main characters hate each other at the beginning, but the way he acts in front of her is sometimes super bad and sometimes way too close. He's supposed to hate her but inbetween there were so many times he was unnecessary overly sweet to her. He also tries to conceal the fact that they were childhood friends. He accidentally called her "nu" (which I think you only use when he sees her as a sister (?)) and tries to deny that he actually called her that, as she wants to know who he is and why he seems to know so much about her. Now I would understand if this happens like twice but that happend like 5 or 6 times. Every time he uses "nu" he seemed to switch from hate to love which isn't convincing at all. I really love the mail lead but his acting definitely got kinda pulled down by the bad script. I also think he and the female have great chemistry so I hope to see them in another drama together. This one was a huge disappointment to me.
