Bro, If You Keep Simping, I'm Running Off with That Cranky Old Man

One day, I wake up and discover I’m the cannon fodder in a tragic romance who won’t survive three chapters. And my beloved older brother is the devoted second male lead who takes a knife for the scheming heroine, loses a finger, gives away all his wealth, and ultimately dies in the ICU. The disaster starts tonight. Seeing him head out to pick up that green-tea bitch, even though my heart condition is acting up, I tear up the image of the obedient little sister I’ve maintained for eighteen years. If being a good little sister can’t make you stay, then I’ll be a bad girl you can’t bear to leave! “Brother, my heart doesn’t feel right…” I clutch my chest and crumple to the ground. The next second, I call a stranger, my voice turning syrupy sweet. “Hey, handsome, anything you want is fine. It’s my first time~” My brother kicks the door in on the spot, furious beyond reason. Who’s that woman? Never mind! To keep him too busy to bother with the green tea’s nonsense, I spend half a million hiring the poorest, coldest genius at school to play my “toxic boyfriend.” From then on, I act obedient and fawn over him in front of my brother by day, then slap the half-million-yuan contract against his face at night. “Nice acting. Tomorrow, keep gaslighting me.” Watching me act like I’m about to die over my “jerk boyfriend,” my brother, who’s always spoiled me rotten, finally snaps. Eyes bloodshot, he corners me against the wall. “Niannian, forget him. I’ll give you my life!” I lean against my fake boyfriend and smile sweetly. “Sorry, Brother. I’ll protect your life myself. Nobody else gets to take it!”
