Felt like watching something new in C-Drama. Begins as a college romance drama but totally changed into cat and mouse revenge drama in the middle and ends on a lighter note. have some dull moments but those will be matched by romance portions.
Mostly will work for all who follow C drama. in beginning Some will hate ML's character for his ruggedness and wont care attitude but they will get to used to it in upcoming episodes. I really enjoyed 2nd half more than first half. College romance portions are bit boring compared to office romance between FL and ML

Go for it !
