I am pretty much new into C drama as compared to k drama. I haven't watched any work the Leads before so I am not biased anyway.

The story is good, could have been better!!
Song Yan (ml) and Xu Qin (fl) were a couple and loved each other like crazy but fl's mom is a snob and tore them apart. After years they met and the story starts...

The good parts -
Omg the rescue scenes, these are really worth watching the show. So realistic and well executed screenplay.
The emergency ward is also pretty good and also worth watching.
The charecter development of the FL is good thing to watch, she eventually moved on from her toxic family and realised that the toxicity of her mom is something she must deal with in order to keep her own peace.
The loyalty of the ML is just unrealistic yet it's something a girl can cherish for. His charecter development is also good.
The tension between the two is something to be enjoyed in this show. Whenever they are facing each other the emotions just come out and quite visible from their expressions yet they try to hide and it's really add perks in their chemistry.

However the parts I really didn't like-
Many episodes feel like repeating the previous one. I mean it was predictable that in next episode there will be a rescue scene and Qin will approach Song Yan when she is absolutely clueless what to do if Song Yan comes back, because she has no guts to leave her toxic family.. later on she matured and moved on but that could have been done without repeating episodes.

It's a good watch, I enjoyed a lot and I would say it's a must watch for once!
But ngl I won't rewatch it as it's too slow.

P. S - Yang Yang is too hot to handle ;-)
