i suggest you to watch all episodes without much gap, so that you will get that feel, Feles like a nice realstic story line , there no bad characters or bad people in the drama, kind of pure love story, from high school to adulthood.

Watching the drama feels like , spending time in nature,like i told like a cool summer breeze.

But the last episodes are good, but kind of felt like, little bit boring, i really felt sorry for the NJ character, i heard many fans supported a different story line, Korean dramas never stop doing these triangle love stories, it hurts when all the characters are good ones like in this drama
