How to Change a Tragedy Novel into a Healing One

I’ve reincarnated! As the younger sister of the perfect female protagonist who is pretty, kind, slender, and even has a good heart. The problem is this novel is a 19+ rated tr*shy novel, and the male lead is an attractive man but he’s a real crazy X with madness. And my sister was supposed to face an ending as a ‘paper doll’, losing her mind due to his obsession. I can’t let my sister, the prettiest and kindest in the world, face such a miserable end! From now on, I’ll take control of this novel’s genre. Not a tr*shy novel, but a healing one! * * * It’s okay. I’m not my sister. I’m not as pretty as my sister, so the male lead shouldn’t fall for me. “You’re cute.” A word that couldn’t possibly come from the cruel and cold-blooded male lead slipped out. …… Will it be okay? I don’t have the fragile wrists that the male lead liked, nor the waist that could be grabbed in a handful, nor the skin as white as pallor, so he shouldn’t fall for me. “You can’t run away. You can’t go anywhere.” …… Will it be okay? It wasn’t a hot first encounter like in the novel, and the male lead wasn’t as crazy as I thought. Then, it should be okay…… right? “How should I describe my feelings right now, wanting to strangle the bastard who touched you?” It seems like it’s definitely not okay!!
