Story: This show has a good balance of romance, angst, and comedy. The romance is well developed and I love how devoted the ML is to the FL. The angst doesn't drag on like other dramas, but instead it serves its purpose and then its is resolved. The show contains fun comedy and endearing characters. There are plenty of side couples and it has a happy ending.

Also I don't know what was the budget of the show but they put in a lot of detail. For example, the wedding is the most extravagant and beautiful that I've seen in a Cdrama. In most dramas we just see the bowing but here we see the whole ceremony.
The drama isn't oversaturated with light nor is there excessive skin smoothing. It was just very nice to look at! One can see that the production team put a lot of work into it.

Acting/Cast: I wasn't familiar with the leads but I thought they did a wonderful job and had great chemistry.

Music: I enjoy the OST- especially the ending theme.

Overall: This is one of the best rom-coms of the year and I would highly recommend
