The story is fantastic, especially the evolution and discovery of Knock true feelings. I loved the chemistry between the main couple, it was just wonderful. The most romantic scenes want it you to see them again and again... I enjoyed it a lot.  The friendship of Korn and Yiywa surprised me very much. Her character, in my opinion, was what they needed to take that little step to be together. Her personality was fun to watch, beautiful and strong. Perfect to unite couples.
There were times when I hated Knock's attitude because although he might be confused with certain situations, he can notice the bad intentions of others, his girlfriends was a total bi"#$.
