Don't Pretend to Be Good

[Both leads are sexually inexperienced + the second male lead wins her over + stealing someone else's girlfriend + falling in love after all] * Sang Yu attends a party as Shen Si's girlfriend. Dressed in a sexy red gown, she stands out among the hedonistic revelers. Everyone knows Sang Yu is only a substitute for her twin sister. Shen Si even says, “It's just a bit of fun. Sang Yu could never compare to Wanwan.” Xie Shangli stands by the second-floor railing, looking down at the scene with an indifferent air. “She is beautiful.” “But utterly boring.” “I prefer mature women.” * Xie Shangli comes from an elite family. He's aloof and reserved, and always keeps to the rules. But a week ago, the famously well-behaved girl treated him like a gigolo and paid for a night with him. The next morning, she not only pretended not to know him, she became someone else's girlfriend. Watching the two of them together, Xie Shangli's eyes redden with jealousy. A chair comes crashing down from the second floor. Xie Shangli deigns to befriend Shen Si, a man he looks down on, and, pretending to be drunk, calls Sang Yu his “girlfriend.” * When his first love returns from abroad, Shen Si wavers before ultimately giving up Sang Yu. Everyone waits for Sang Yu to become a laughingstock, but she neither cries nor makes a scene. She calmly arranges to meet Shen Si. Xie Shangli goes mad with jealousy, gripping her waist and pulling her into his arms. “I have money, looks, I'll always take your side, and I've got morals. Haohao, why won't you choose me?” The Shen and Sang families celebrate their marriage alliance, and Sang Yu is completely cast aside. Even her own family throws her out. Everyone expects a spectacle, but instead they see Sang Yu, dressed to the nines, appearing among the ultra-wealthy elite. The proud, untamable heir leans against her shoulder, pretending to pout. “Haohao, when are you going to make things official with me?”
