My Sister is a Big Star(2021)

Wo De Jiejie Shi Da Mingxing

What? My older sister, who's pretty but lazy and abused me for fun, was born from different parents than me? What? She wants to become a superstar? Fortunately, I have a System to help cheat her way to stardom. What? My parents asked me to help her find a boyfriend? I’m still single, too, why don’t you guys care about me? ! The System suggested that my sister and I are quite compatible, and the System can help pair us up. No way! Being her brother is already bad enough!
