Why Does the Villain Cry Every Time I Bring Up Divorce?

[Transmigrate into a book + Marriage Before Love + Slow-burn sweetness and angst + Yandere + Mildly coercive + Winning her back + Both leads are each other's only one + Mutual salvation] [Devoted, scheming husband with a soft exterior + Gentle, slightly social-anxious good girl] After transmigrating into a book, Su Nuoyu ran away from her wedding. But on the way, she ended up saving the very mad-dog villain who was supposed to marry her! To avoid getting involved with a madman, Su Nuoyu decided to pose as his little sister and made a deal to divorce him a year later. But Qi Huaiyi's feelings for her grew increasingly strange. First he deliberately engineered chances to touch her, then he tentatively kissed her hand, and finally he kissed her while drunk... His possessiveness ran so deep that he planted a bug on her. The day she found the bug, she had just started dating Qi Huaiyi. Su Nuoyu panicked and ran! When they met again, the man everyone feared and avoided like the plague cornered her against a wall, eyes red from crying, and trembled with a wounded voice: “Baby, just love me.” “Please... I'll be good, I promise.” “I can do the laundry, cook, clean, and earn money.” “Baby, didn't you once say you wanted a dog? How about me?”
