The Most Powerful Sister-In-Law

I am the strongest top player in the world who failed to express my love. I thought my life would be so routine and peaceful. But some things changed unexpectedly. Why do the transfer students who came from the sky seem to be my crazy fans? Why did my childhood sweetheart start acting like a monster? Why... My sister who is a top student is being tortured! What color will the campus of youth and dreams look like together? I don't know either, but it must be full of laughter and flying petals, right? This novel and its characters are purely fictitious.
