Story: The plot was more original than most C-dramas and was very decently developed.
The SWAT team and the hospital scenes were interesting with not too much technical language, so easy to watch.
Also, I like the dynamics in relationships between friends, couples, colleagues.
It is basically a nice slice of life, with no twists or complicated arcs.

Acting/Characters: It was my first time watching Bai Jingting and Sandra Ma, and I can say they are great actors, they portrayed their characters very well.
Mi Ka is very calm, courageous and caring. She is very different from the stereotypical female lead.
Xing Kelei is the typical perfect male lead: handsome, good in everything and charming.
Their romance is so pure and slow-paced, they act like a 10-years married couple, so don't expect anything passional.
As for the second couple, I didn't like it, the SFL was very intense and the SML was indecisive. It was draggy, annoying and a mess. But don't get me wrong, they were nice characters in their own.
The third couple was a lot better, more mature and healthy.

Music: The songs were very nice and catchy. I put some of them in my playlist.

Rewatch: Yes.♡

Overall: I enjoyed this drama a lot. I don't consider it a masterpiece, but is so captivating that I understand why reviewers say that.
