Firstly, our female lead dies in her world. Surprisingly it was Ancient China and I guess she leaped in time after death? That's underwhelmingly dumb and lacks imagination.
The body she took control of belonged to a girl, that even though being hated by her whole family for being a bastard child she somehow managed to marry the guy she liked. That same guy was pursued by both of her older half sisters and he never really liked her, in fact he hated her because she was a brainless pig with no talents, education, manners or anything going for her. He was even disgusted by her looks although later we find out she's maybe best looking girl around? She was supposed to be an annoying woman that bothered him.
Meanwhile she cut her wrists once in front of him and he gave zero f*cks. Then she was in an accident and miscarriaged their child. He wouldn't even touch her and she had to drug him to get prego. He still didn't care about her or their child (later though retarded author is trying to make male lead more likable adding that she was a drinker and kid would be a ret*rd so he didn't want it but still was fond of it). Nonetheless it's apparent that male lead is a lacking prick with just money and looks.
But after the transmigration and our female's change in personality he falls in love with her because she ignores him. Author is still trying to fix male lead's image by saying he didn't just marry her because his grandfather liked her but he also got interested in her because she stood outside his door for 3 whole days when he was little and his parents died. A thing which most likely happened when he was 13-15 and she must of been 5 or 7. Like wtf?
Moving on, there's not actual plot it's just evil sisters scheming against her. Which also doesn't make sense, how did all 3 sisters fall in love with him? Also the repetition is ridiculous, female lead is described as if she was Xena The Warrior Princess or Gabrielle in past life but in this one she keeps getting hospitalized every 10-20 chapters. And what makes it worse is that author keeps adding that she should workout but it somehow gets forgotten each time and she keeps getting injured.. Now let's focus on 2nd sister and the reason I dropped this novel, it starts off with her being mildy annoying and bad and all of a sudden you have her setting death traps and gang r*pes for female lead-her sister. At the end she is caught by male and female lead and is put into a factory prison owned by male lead but next day somehow she has syphilis, is r*ped and dead in that prison cell that was guarded by 2 people.. I'm honestly speechless with that. Finally both jealous sisters (before one dies) keep being neglected and keep thinking that they are envious of their sister (even when male lead is scolding them) and that they hate female lead. Honestly it's not worth reading.
