The Villainous Saintess Dug Out My Bones, Then Became My Biggest Simp

[System + yandere + twists + wish fulfillment + one female lead + pure love] Lu Xun transmigrates into the body of a good-for-nothing young clan heir. The very day he binds himself to the [Face-Slapping System], he's already plotting his comeback. But then the Demon Clan's Saintess kisses him by force in the middle of the street and takes him home against his will. “From today on, you're mine, little darling.” Dressed in red like a blazing flame, she speaks boldly and is always saying things that make his face burn. She helps with his face-slapping plans and risks her life to protect him when he's in danger. Lu Xun can't figure her out. Sometimes he thinks she's a threat; other times, he finds himself longing for her inexplicable protection. Until one day, the “Innate Dao Bones” sealed inside him suddenly stir. And Su Li, who has always smiled sweetly, shows a complicated expression he has never seen before. Even the System's alerts begin to sound strange: [Warning: Extremely high-value target “Su Li” harbors intensely conflicting intentions toward the Host.] [Analysis: Target behavior pattern: “possession” and “destruction” coexist.] Lu Xun: ??? So what exactly does this Saintess, who says she loves me every day, want from me?
