I watched this for the chemistry of the main leads. I'm not going to lie. I am a romance junkie. As others have said before, the story is super cliche and drags in places. The two main leads, however, basically smoldered whenever they were on the screen together. It was tough to get into the story. It took me a good 3-4 episodes before I was hooked. That being said, after a while I felt that the two main leads were written to be 'too perfect' if that makes sense. They always did the correct thing or said the correct thing in any situation which made them not very realistic imo. The secondary characters were also charming and helped keep me watching as well. I adored both sets of parents and all of their friends. However, I didn't really care for Nana's and Quinyang's story, just how I felt personally.
I wouldn't rewatch the whole thing, but I admit to already rewatching the kissing scenes. *fans myself*
