I don't know whether I hate or love this one. The story was bit draggy at times, and I skipped some episodes in the middle, but I don't feel this drama is as bad as people claim it to be. Although the story was messy, yet it was great to watch the budding campus romance. The actors had a great chemistry, and played their parts well.
The music was the winning point. Literally it had some of the best tracks, and the osts stand out to be the best of the kdrama world.

Binge watch it on the weekend, when you don't have anything to do or watch, but don't keep great expectations.
