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!
