I watched it because of Park Eun Bin (I lover her so much in King's affection)
This drama started quiet interesting - so no wonder it got all those attention and early news of American remake.
However just like most kdramas that suddenly got too much praise... the drama started to get boring after episode 6 - either the writers got pressured from all the attention or they really didn't know how to continue later on.
In the latter part of the series it felt as if things became repetitive. So many plot holes that was ignored since the story started to focus on romance and side characters.

I dislike the romance for the main couple, we never get any background story about the ml and how he started to like fl, it honestly bothered me so much... because I feel like watching a fully grown adult grooming a child. It would've been better if they were just friends or the romance was properly executed.
