I didn't expected this series to be good. I saw the run time and my expectations were low. But I gave it a try anyways since it was short and I had nothing to lose, and I am glad that I did and now I am regretting that it is so short. This series has the plot to stretch it to a 16 episodes with 1 hour runtime. We need a depth of how they met in highschool, their story in highschool, the reason for Dong Wook insomnia, how they first fell in love, Dong wook's reason for the misunderstanding should also be expanded more, just because he saw Do Hyun laugh with someone who is not him is not a good excuse. We need dept. BUT STILL they managed to make it good. Even with the lack of dept and run time. I am actually surprised. Another thing I love about this is the skin ship. Actually a good kiss which is rare in KBL. I wasn't even expecting one or i was expecting a bad one, but they actually did pretty well. So applause to that. The actors did well. Kinda here a there more emotions is needed but otherwise okay. They had really chemistry with each other. And also I am looking forward to the romance of the 'second lead' since he didn't really do much to be even consider a second lead. So in conclusion this was good, But could have been better with more episodes. Still overall very good.
