My Sister is a Superstar

After years of working as an office lady, his troublemaker sister suddenly quits her job and says, “I want to be a star.”
Qin Ze, a normal second-year college student, replies calmly, “My dear sister, do you have a death wish? Father will kill you, and I won’t object.”
The spiteful sister responds righteously, “Qin Ze, you have been living with me for so many years. You are destined to be my scapegoat!”
“Thank God, I have a System to back me up.”
This is a story of an older sister’s continuous exploitation of her younger brother, starting from her first step of being an idol to more personal gains. And it so happens that he has woken up to a System that could help him deal with that and all the troubles that are bound to come his way.
She wants to a star so he wants to be king!
