This entire show can be summarized as the power of one woman's obsessive love and sacrifice.

Pros:
1. Fantastic chemistry. Really top-notch acting from both leads. they suit each other. especially Zhang Jingyi. I can feel her yearning, her boundless love, every time she looks at him. Their romantic moments seemed so visceral and raw, it almost felt voyeuristic.
2. Beautiful music and the editing really emphasizes it. The songs were placed with much thought and really heightened every scene.
3. Well-written villain (Gao Jianhong) for most of the show I heavily empathized with his feelings of insecurity, shame, anger and despair. He was indeed mistreated by the male lead and sometimes female lead too. Some of his actions are not justifiable but you can really understand why he became the way he did which I think is important in these revenge stories

Cons:

1. We, as the audience are aware who the main lead is but in this show all the characters also act like Li Xun is the male lead. It's like he has the protagonist halo. The supporting characters all behave as if they know they're just extras. It doesn't matter that Li Xun is rude, cruel and arrogant. He can yell at his friends. He can yell at his colleagues. He can humiliate them in public and they just sigh and say 'oh well thats Li Xun for you' 'hes smart and handsome so he can do and say whatever he wants'. It was so unrealistic. Nobody in real life is that passive or accepting of terrible behavior no matter how smart the other person is.

2. The way their relationship and ml and fl character arcs are written is so particularly infuriating. Straight-A student Zhu Yun who is perhaps tiring of her parents' controlling nature meets arrogant, brilliant, mysterious and carefree Li Xun as freshmen in University. She is somewhat fascinated by him but mostly they get on each other's nerves. But she acknowledges his genius and they fall in love as they work together. Ever since their partnership in the programming base, Zhu Yun is particularly loyal to Li Xun. She stands resolutely with him no matter how rude or cruel he is to her friends coz ultimately he is right and they are wrong, he is smarter and better than them so she and all their friends need to be accommodating of his cruel brilliance. She's probably the only one in the show to even try to confront him but rather than confrontation it's more of a compromise. She ends up agreeing with him anyway or justifying his actions. They begin a romantic relationship coz she chases him and swears she will forever be unrelentingly supportive and kind and submissive. Then he goes to prison. You'd think their characters or relationships would change after this huge shift but no. she's still blindly sacrificial and supportive and giving while he teases, insults, sneers and is at best detached. When they finally get together it's not a happy moment coz I didn't feel for one second that he loves her as much as she loves him. All the sacrifices, all the adjustments, and all the pain in this relationship have been borne by her. He gives nothing but he takes endlessly. The development to their reunion is shoddy at best. Once again they get together coz she pursues him. They don't even have one real conversation despite having gone through so many traumatic changes.. Everything is swept under the rug to tie the endgame up in a nice, pretty bow. The audience is still left with the feeling that they know as much about Li Xun as they did in the first episode and he still is that arrogant college freshman. You're left feeling something akin to pity for Zhu Yun coz you know for the rest of her life she alone will be bearing all the responsibilities and the emotional weight of their relationship.

Perhaps I am in the minority but alas I could not enjoy an unequal relationship where all the burden of the sacrifice and the fate of the relationship is solely on the female lead.
