It's a typical Chinese novel story. The female character is a successful business woman who seems to have a perfect life, then later her man cheats on her with a family member either a cousin or literally her little sister (weird, but I promise this is the common trope)
The MC goes back in time, now correcting her mistakes and meets a new guy. In this story the new male lead seems pretty normal but since this is a Chinese story, the guy for sure would be later revealed to be secretly very successful and rich and is a CEO but hides it from the public for some reason. hahaha
Same, they try to hype the Female lead up by making her soooo smart but she's actually just alright. For someone struggling to survive, she's okay. Not amazingly smart but just average. She says she doesn't want to be "his majesty's woman" but that's exactly what she's become, she's in conflict with her own character. Author can't decide what trope the female lead false to, either strong independent woman or damsel in distress
If it were me I'd just kill hime with my ability
