I Transmigrated Into a Torture Romance, But I Only Want to Go Crazy, Not Suffer

A super-strong heroine fakes madness and beats the whole family senseless + A paralyzed, unhinged hero dotes on her alone "A hilarious tale of going feral: one wrong word and she's throwing punches, beating up her dad, mom, and siblings." Su Ran accepts a transmigration mission and becomes the abused heroine in a CEO novel. The original heroine had a hard life, a wounded heart, and a cruel fate. But Su Ran is different. She transforms the abused heroine into a triumphant heroine. She curses out anyone she can't stand and beats up anyone who dares bully her. Her temper is explosive, and if you want to mess with her, better make sure you can take a punch! Huh? Why has the paralyzed hero from the book suddenly become a different person? Didn't he hate her? Why is he suddenly clinging to her? Help! She doesn't want this! It's fine. My legs are my own, after all! If I can't take him on, I can run away! But why is the hero getting more and more strange? Oh no, he's gone crazy! Run! Oh no, there's no escaping now!
