I loved loved loved this drama, mainly because of its level of authenticity. And realism. There are ten episodes that focus on the story of two characters, who fall in love little by little, but it also focuses on their individual stories, especially Seo Jaewon.
What I found most special about it was the way their romance was portrayed.

Watching it, you could feel the tension and the characters really falling in love, which I really appreciate in romances. I've always followed Thai bls and they lack that, most of them at least. The lack of authenticity, the exaggerated, funny and cute way of expressing the characters' love. There's nothing wrong with that, of course, but I personally like this kind of romance better. It was something simple that we could tell even by the way they looked at each other. That's why the actors did an excellent job too. Their chemistry was amazing.

The editing choices were often not the best, although I realize that most of them were for cinematographic and artistic purposes. However, some of them didn't make sense, which I wouldn't exactly point it out as a serious issue.

Otherwise, I think this drama should have had either full hour episodes like regular dramas, or more episodes. Otherwise, it would have been good to have a second season that further developed Seo Jaewon's story, his depression, his relationship with his parents, etc. It was more of a secondary plot, although fundamental to the story, but it would have been interesting.

Regardless, I RECOMMEND IT. Please watch.
