First of all, very beautiful OSTs. The OSTs definitely carried the drama to a higher place. It is one of the most beautiful songs I've heard in K-dramas.
The story of this drama revolves around the good parts and hard parts of being in a relationship. I think there were some relatable moments to it which makes you think back and ponder over them. The story was overall good. There were a lot of thing happening and they did a good job wrapping everything up in the end. I would say the story falls off a bit in the middle and the main characters literally switch their personality which was a bummer as I would've loved to see the female lead as she was in the first half of the drama, tough and strong. But it was still good and the change made sense. The side characters were good but they didn't have any character buildup to them, they were just there because they had to and for some comedy relief. Except for NJ. I loved NJ.
The cast and acting was good.
The Cinematography was good and made the drama that much more enjoyable.

This drama is not perfect but it did everything right and it paid off. This drama was overall a great experience and I would definitely recommend people to give it a watch.
