The System Insists I Go Fifty-Fifty with My Vicious Stepsister

Reborn in his senior year of high school, Su Xiaochuan finally understood. What good was being the young master of a gang? What good was having a long-legged older sister? It was all meaningless. Only an acceptance letter from a top university was real. The male lead is a reborn heartthrob with a calculating mind, beloved by everyone at school, who only wants to reclaim his former glory. The female lead is the true heiress of a billionaire family and the light of his life. Now that I only care about studying, surely you can stop treating me like a rival? The System awakens! What do you mean, a [Shared Study System]??? Want the rewards? Sure! But the rewards have to be split fifty-fifty with the vicious older sister who personally killed him in his previous life! ...? ...? ...? For the sake of his university goals, and because knowledge can change one's fate, he has no choice but to do everything he can to clear obstacles for his older sister and provide her with a good “study environment.” School bullies getting in the way? Get lost. School heartthrobs causing trouble? Get wrecked. Wait, the billionaire family's true heiress? Wasn't she all sweet and innocent in his previous life, only to get him locked up? Why is she looking at him so strangely this time, and even offering to help him study? It must be another trap! The skills he pays a price to exchange for, his sister masters effortlessly and unconditionally? Why? And to keep his sister from finding out, does he have to keep making up perfect stories to explain how she mastered all those abilities? Looking at his bank account, where Su Xiaochuan has already achieved financial freedom, he finally stops obeying the System and tries to keep his distance. But his max-level sister finds him with ease and corners him. “I already missed my chance once. I won't let you slip away again in this life.”
