She Wants to Be the Heroine and Her Sister-In-Law

I am very happy to dress up as the vicious female partner Wen Ning. She couldn't afford to offend the male and female protagonists because they had the aura of protagonists, but the female protagonist's brother was Wen Ning's deskmate. The heroine's brother is a girl-controlled autistic person. Wen Ning said lightly: "Xu Yan, your sister asked you to pick her up at the city library." Xu Yan, who never deviated from the established route, got lost. Wen Ning: "Xu Yan, your sister ran away with someone else because she was short of money." Xu Yan won 30,000 yuan in a game without saying a word. OK! An autistic person has such an IQ, so Wen Ning can only use his trump card. Be the heroine's sister-in-law!
