Before the College Entrance Examination, My Sister and I Exchanged Systems

On the eve of the college entrance examination, my sister was bound to the God of Love system, and I was bound to the God of Study system. So she didn't have to hug the whole class to hug the top student, and directly won his heart. And I was admitted to Tsinghua University together with the top student. In order to keep this love, she gave up going to a different university and chose a local junior college, where she studied with him day and night. Soon, the top student got fed up and broke up. But I met him at the top of his game at an international competition. My sister was so jealous that she pretended to lay flowers on the podium and stabbed me to death. Opening her eyes again, this time my sister bound to the God of Learning system without hesitation. "Sister, you will be the brainless vase this time, and the top student is mine!" I smiled. She doesn't know that I am a top student myself.
