This is a very watchable show, but its plots and tone change so often that you feel exhilarated and exhausted in equal parts. This makes it hard to give a concise rating. When it is good, it is heartfelt and stirring. But it can also get cheesy with a side order of jingoistic flag-waving. I suppose my rating is between 8 and 8.5.

At its core, this is about the aborted love story of a pair of teenagers who met towards the end of high school. Their budding relationship was torn apart by the FL’s domineering mother. They met by chance ten years later and things develop from there. If the plot sounds tropey then here's your gold star. This show walks on familiar paths but it does set a cracking pace.

During early episodes, our leads would "chance" upon each other repeatedly. When you realise one is a firefighter and the other is an ER doctor it means they only meet at emergencies. Consider even a small city in China can house millions, that’s a very small but dangerous corner they live in! It feels so contrived and is almost farcical.

All these entanglements finally brought them back together and this is essentially the glue that held the show together. Once we get past the push-pulls and denials, we have a very romantic pairing. Our leads have good chemistry, and they are certainly photogenic. It was gratifying to see the FL grows a spine and stands up to her controlling mum once she is all in. Amore trionfa sempre!

While both stars are beautiful people, Yang Yang is the face of this show, and he is everywhere. This can cut both ways. Fans of YY will rejoice but someone who is less enamoured might start to notice some flaws in his acting.

The other star of the show is the firefighters and their daily grind provides most of the subplots. A shoutout to the ensemble cast who filled the ranks. They must have trained hard for their roles. Some of the action/training scenes look very challenging. They are ably supported by the staff of the ER department where the FL works. However, these plots are a mixed bag. It can go from inspiring and exciting to banal. I appreciate the work of first responders, and I'll not begrudge their moments in the sun. However, some of the dramatisations are over the top. Plots and pacing is uneven. There are a lot of nationalistic messages aimed at the local audiences. Your mileage will differ.

The mother of the FL is straight out of central casting. She is the personification of a rich, immoral, domineering matriarch. She can probably trace her matrilineal line to a Tang Empress. She is a force of nature and rules with an iron fist. The only problem is that her role is very one dimensional. Her only goal is to obtain power, wealth and a total control over her serfdom. She never has a moment of self doubt or regret. It is tiring to watch her do the same thing over and over. Her “Death Bed” conversion feels particularly contrived.

In the end, fans of the leads will be happy, the production value is high, particularly some of the action set pieces. There are impactful and poignant moments that will stay with you. The romance is sweet and swoon worthy. Once the OTP get together, they skipped the handholding and went straight to home base which is rare in a c-drama. However, it is an inconsistent grab-bag of highs and lows, original ideas and contrivances. This annoys me because I really wanted to recommend this show unreservedly, but I can’t.

I can certainly rewatch some of the romantic scenes (repeatedly) but not the whole 40 eps. OST is very nice.
