This is one of the few kdramas I'm aware of that touches on mental illness, without just using it as a plot device. While I'm not fully satisfied by the accuracy or the depth into which they've delved into the topic, as far as I'm aware of, it's not something that's explored as much in conservative Korean culture, so for that I think this drama deserves recognition.

This drama also explores a more mature relationship between characters who each have their own flaws, which is refreshing in the romance genre of kdrama. The two main leads display superb acting skills and make their characters charming and believable. While overall the drama has a more serious tone, the strong side characters provide plenty of humorous moments. It was nice to see such supportive friendships between the characters.

The soundtrack is also one of my favourites, and differs from your typical kdrama OST in their song selection, which I appreciated. The soundtrack definitely added to the tone of each scene.

The pacing was also excellent as I never felt it drag and the storyline kept driving it along until the very end. There were heart-wrenching scenes, but it never felt too overdramatic or exaggerated and everything--the events, the characters' reactions--felt realistic.

I can't think of another drama where I enjoyed everything so thoroughly and I would definitely recommend this drama for those who are looking for a more mature romantic kdrama.
