First there are two versions of this. The original is 65 episodes. I first watched it on Netflix with only 24 episodes. My wife watched the full 65 episodes and watched the last two episodes on Netflix with me, she couldn't stop complaining about all the missing information, including people never appearing in the 24 episodes. She was very upset with the ending.
It did make me understand some of the crazy things in the Netflix version. Scene cuts and sound changes that looked like poor production values were because of editing out two-thirds of the episodes. Half of the last episode is flashbacks with one new scene at the end.
Still, this is better than your average Asian drama. It is the standard fat person, Mi Duo (
Yan Tang), who suddenly gets thin. There is just enough background to see her life in a fat suit. She is seriously hurt in an accident and undergoes major surgery becoming thin and beautiful. This gives her more confidence and changes her life, she begins working for a company where the CEO, Xiao Liang (
Rain), was once kind to her as a fat person, so naturally she will fall in love with the CEO. But, she does have a childhood friend, Lei Yi-MIng (
Jin Luo) who is now a doctor, also lives in Shanghai, and, while a former womanizer, is just beginning to understand he loves Mi Duo.
The rest of the drama is just the normal break up for this reason, get back together, break up for that reason, get back together, etc.
My wife insists that I watch the full version, so I will come back and update this review afterwards.
My wife tells me that in real life
Yan Tang and
Jin Luo are a couple. If you like them you can also see them in
Jin Xiu Wei Yang (2016), which I have seen and liked it better than
Diamond Lover (2015).
