I enjoyed the drama for a while. The romance and comedy was good until the mystery part came in. After that it became too draggy. There was also a villain in this drama, which I felt was unnecessary,

The positives: the high schoolers, female lead's brother, and the male lead

The negatives: the female lead herself - her character was super annoying, like she'll always interfere in every issue and even justify her actions by shouting, she even failed to be emotional in situations like where to cry, being surprised all she did was covering her face with hands. There was very little to no romance at all between the leads, I'm not saying this because the female lead looks much older, I'm saying this because regardless of age one can express the love, that the viewers can feel, I never felt the romance.

I wished the story just stuck to the real storylines of these kids and their struggling through school at this crucial time and kept it a simple yet emotional coming of age storyline not only for them but for the adults in the drama.
