I'm having trouble finding this novel I read, I think I remember it being a chinese novel . but so like the mc is a girl that got reincarnated but like she doesn't get the memories of the original owner, so she has to figure everything out by herself. And since super good at science in her last life she got number 1 in science in the province. She also started dating her best friend's brother, and turns out she might be from a super rich family.Oh also even though she doesn't have a good relationship with her mom and sister she does with her brother, but they aren't actually related cause she was birthed from her father's first love, but couldn't marry her cause he was too poor or something like that. oh and she got a bunch of teachers to teach her stuff like self defence and quzhong I think I don't remember the exact instrument but it was a traditional chinese instrument I think. Although I don't remember much do you guys happen to know this novel?
