I liked this drama at the beggining. I loved the girl, her smile, her overall cheerfullness despite being afraid of ghosts and I loved the developing romance plus the chemistry between the leads which was pretty good. That was all untill episode 11-12 when everything started to fall apart. There was just too much unnecessary drama! I mean the CEO did everything for her, he died for her, he rememberd the unrememberable, he visited her as a ghost...What else is a guy supposed to do? I thought the two were just a perfect fit and do not get what was wrong with him being her safe shelter? Aren't in real life our partners people that we are most voulnerable to, aren't we each other's shelters and places of comfort? I just didn't like how episodes 12-16 developed, I seriously started not liking the female character, and her going off with a total stranger who just popped out of nowhere was too much. I felt irritated and sorry for the CEO and almost dropped the show. Luckly, episode 17 returns the girl to her true character and we get the happy ending after all. Because of the mess the writers made from episodes 12-16 this show has no rewatch value. They annoyed us and almost made us hate the main character. I wouldn't go through that again.
