A Royal Heir's Passionate Indulgence of His Beloved Wife

[Arrogant, powerful crown prince vs. heiress with a tragic past] [Both are romantically inexperienced + one-on-one romance + happy ending + nine-year age gap] [Neither lead is perfect. The heroine isn't a self-sacrificing saint or a naive, harmless flower. If someone has to take a loss, she makes sure it's not her!] Qin Shujue is the crown prince of the only royal family in the modern world that still holds real power, the Kuman royal family. Because his mother is Chinese, ambitious members of the royal clan scheme against him and attempt to assassinate him. Zhuang Nuannuan's father dies saving Qin Shujue, and her entire family is killed. Only Zhuang Nuannuan, still a baby in swaddling clothes, survives.
