Billionaire's Contract Girlfriend

Lu Shiyan hires Su Nian to pass as his girlfriend for one month so that Wen Ruoxi will drop her pursuit of him. He pays 500,000 for it, and Su Nian, who has been scraping by in Jiangcheng, signs. He takes her back to the Lu house. His mother does not believe them. Wen Ruoxi does, and she comes after Su Nian in public and humiliates her in front of people. Lu Shiyan takes Su Nian's side each time. At a conference on traditional medicine Su Nian sees that the xuanshen in a preparation has been swapped for danshen, and she says the wrong mixture can suffocate whoever takes it. Wen Ruoxi has the trial run anyway and one of the researchers nearly dies of it. Su Nian mixes the medicine again and gets him breathing. Wen Ruoxi then tells the room that Su Nian caused it, and the crowd closes in on her. Lu Shiyan walks out and puts her behind him.
