My Sister Is A SuperStar

What? My elder sister, who is lazy, charming, and abusive, is not born of the same parents as me? What? She wants to be a Superstar, but fortunately, I have a system and a cheat. Help remove all obstacles in her way! What? My parents asked me to help solve her single status problem, but I'm still single! Why don't you guys care for me!!! The system said: I think the two of you are quite suitable, and I will match you guys up. I won't do it, As a brother, I will protest against it!
