The poor girl Tian Yulu has always lived a life of unbearable hardship, until one day, a very strange System set its sights on her.
System: "Oh, maiden, do you yearn for yuri?"
Lulu: "No, I just want to save my seriously ill little sister."
System: "Oh, maiden, you can save your little sister by acting cute. Will you sign a contract?"
Lulu: "For my little sister, I can even sell my dignity! (With a serious face)"
System: "Then the contract is complete. If you fail to complete the tasks issued by this System within fifteen days, the Host will become a good-for-nothing who sells herself..."
Lulu: "Huh??? This isn't what we agreed on, you bastard!"
