Most of my grievances will be with the story, so deal with me...

Story:
The storyline manages to deal with multiple themes in maturing adult life, such as changing jobs, family, and the pressures of getting married in Chinese society in particular. With all of these come moral compromise. Each character had flaws, sure, but I would have preferred that the director deal with them and show the watchers that their attitudes in regards to certain situations was not OK.
He Canyang was correct that his parents favored his sister over him, and when he tried to stop Fanxing from telling her family that she dated Yuan Song out of consideration for their feelings regarding what they had just discovered about him and Cai Minmin he was the one that got hit. Having his parents deal with Fanxing in the same manner would have been way better, in my opinion. But I get that they only had a certain number of episodes left, and that would have posed yet another barrier in her finding her true love, yada yada.
As for He Fanxing, she's way too wishy washy. I get that she's "innocent in love," but why couldn't she take into consideration how she was stringing two men along? She explicitly broke the promise she had with Yuan Song that they would go public after three months, and dated Ye Luming (although he knew she was not totally in love with him and was okay with it, being hung up over your ex boyfriend and hiding it is ridiculous). She wanted to walk Ye Luming down the aisle for her parents, but never considered that she would be locking Ye Luming down in a one sided relationship. Had the sideplots with her friend group's pregnancies and her father's terminal illness not happened, the show would have consisted of over 40 episodes of her going on meaningless dates grappling with herself and picking the petals off of a daisy to choose between going public with Yuan Song or not. She legitimately cannot take a hint, if you broke up with your boyfriend & got a ride back from the guy who likes you you are out of your mind.
Ye Luming's role in the first half of the show consists of him being manipulative and using societal pressures to get Fanxing to be with him. He already knew that the reason Fanxing wasn't coming out as dating Yuan Song was because she was scared of what people would say, and he used that while they were dating to get her to be with him. He moves way too fast in the first week of their dating, without considering how she had never been dating openly before. Hell, he sleeps in her bed without her permission.

Honestly, I hate age gaps in relationships. I only finished this to see where it would go after a while, and because SQ is hot. Each of the relationships is not realistic. Cai Minmin and Yuan Song both make the first move on the He siblings, who are in positions of power even without the age difference. A boss and her employee? A professor and his student? How many times does an older man change his profession for the younger woman that he is seeing? The entire plot sounds like it was conceived in some jilted older woman's memory of her young workplace junior. Just because someone is a legal adult does not mean that they are on the same level of maturity as 30 year olds. There's realistically nothing to speak about, they're basically in different points of their lives. This is more prevalent in Cai Minmin and He Canyang's relationship, at least Yuan Song and He Fanxing are working in the same place. All Cai Minmin likes is eating and buying expensive clothes. Then when her uncle calls her out on it, she gets upset and thinks that having sex with He Canyang will change the immature nature of their relationship. I mean, really? She's harmless, but does not have the range.

The only likable character to me was Chang Huan. He's an example of seeing someone that he isn't fully in love with, but at least he had the decency to stay away from Cong Xiao during it. Can He Fanxing say the same?

Acting:
Done remarkably well, considering the age gap between SWL and SQ is the same as their characters. The chemistry was great. Each character had a variety of emotions and tribulations that they had to go through, and they did it convincingly.

Music/Aesthetics:
The OST is on my Spotify repeats! I really liked the aesthetics of the show, the lighting and camerawork was all great and conveyed whether the atmosphere was close or not. Fanxing's business chic outfits had me wondering what she would wear next. They all looked amazing on SQ's frame.

Rewatch value:
I would not rewatch this... This entire review served to just remind me why a story can tackle many versatile topics while not acknowledging many other problems.
