Ren Guang Xi (Vanness Wu) is a handsome law student whose mother is the dean of his attending college. He had a bad childhood, and takes out his anger on the world by bullying others and taking advantage of his mother’s position. Liang Mu Cheng is a girl who has also had a rough past, but still strives to protect her stepmother from learning the truth about her perverted boyfriend, who sexually harasses her. She can’t stand it any longer, and studies to get into college to leave her stepmother’s boyfriend. Guang Xi and Mu Cheng meet over a dispute about a car, and Mu Cheng leaves Guang Xi with an impression that she is a manipulator and swears to make her show her true colours. Guang Xi then makes a bet with his friends that he could get Mu Cheng’s kiss within 24 hours. He asks Mu Cheng out, and her stepmother, a co-owner of the school canteen, fears that Guang Xi would shut down their business so she forced Mu Cheng to go along with the date. Mu Cheng had her own problems with the date as Guang Xi had threatened to have her best friend, Hua Tuo Ye (Chris Wu), expelled from the school because he gave Mu Cheng a book from the school library, which prohibits students from giving the books to those who aren’t in the school. Guang Xi is successful with his bet and Mu Cheng goes home to a delighted stepmother, who gets so worked up as to say that if she tells Mu Cheng to sell her body, Mu Cheng would do it. She also taunts Mu Cheng’s desire to play the piano again. Mu Cheng stomps out of the house in anger and runs to the college. She finds a piano in there, and plays Air on G String by Bach. Guang Xi is in that very room sleeping, and is reminded of his father, who committed suicide years before. He forces Mu Cheng to stop and begins to accuse her of being a manipulator. He then attempts to make Mu Cheng strip and stops when she starts to cry. He starts to look at Mu Cheng under a new light. Guang Xi tells her to start playing the piano for him every night. Days later, Mu Cheng’s stepfather hears that Guang Xi wouldn’t be able to attend their nightly session and takes advantage of it. He goes into the music room and attempts to rape Mu Cheng.
