Poor Sister, She Can Only Cry on Her Brother's Lap

[Forced love, foster care, double cleanliness, the male protagonist is a pure bad guy, 1v1, 7-year age difference, chasing his wife in the crematorium in the later stage] (Tear-incontinent sister VS pure bad guy) Qiao Xing grew up in the Gu family. Her parents raised her as their own daughter, and even her taciturn brother Gu Xizhou doted on her. But all this changed when she started dating in college. The cold and abstinent Gu Xizhou became irritable and forced her to break up with her boyfriend. When Qiao Xing refused, the man directly deceived her into the villa and "punished" her severely. From then on, Qiao Xing had a deep fear of Gu Xizhou. Qiao Xing couldn't stand Gu Xizhou's suffocating control. She tried her best to escape, but was caught by Gu Xizhou again and again. The first time she escaped and was caught, Gu Xizhou built a perfect cage for her. During the second escape, Gu Xizhou tried to trap her with children. The third time... —— Gu Xizhou's love is very selfish. Qiao Xing is his treasure. He was born to live only for her. She longs for freedom, so he breaks her wings so that she can only snuggle in his arms. Everything is so perfect. But why her wings seem to have grown again recently.
