My Mortal Enemy and I Love Each Other to the Death.

Falling in love and killing each other + mortal enemies + redemption + lasting love Ji Yan is the illegitimate daughter of the Ji family. She has not been loved since she was born. Other people's names bring happiness and blessings, but hers is the only name that brings disgust. Ji Yan was given to the Li family by the Ji family and became Li Jiusheng's secretary + bodyguard. On the surface, she was Li Jiusheng's secretary, but she had no choice but to work for the Ji family, stealing documents and assassinating people. Li Jiusheng knew it from beginning to end, but he wanted to hear Ji Yan tell him personally why he did this. Ji Yan never said it because she couldn't say that she hated this kind of life. Only when she was with Li Jiusheng did she truly feel that she was alive. But Li Jiusheng didn't know that Ji Yan was not only his secretary, but also his mortal enemy and the person in charge of M. L. The two had always been at odds with each other. From the initial fight for business to the incompatibility later, Li Jiusheng had never defeated Ji Yan. Li Jiusheng and Ji Yan are lovers and mortal enemies. The two met for the first time Li Jiusheng was interested; "What's your name?" Ji Yan's living person is slightly dead; "Ji Yan" Li Jiusheng doesn't understand; "That Yan" Ji Yan is calm; "I hate it, I hate it" Li Jiusheng didn't understand; "Why would someone call this disgusting?"
