So This Is the Supporting Female Lead-Saving System

Please support my ongoing story, How Double Standards Are Made. You can read these as separate little stories. They're all one-on-one pairings, so if one isn't to your taste, you can try another. Please adopt my story! As a newly created System, it was supposed to travel far and wide, ride the rails, and lie down on train tracks... Er, no. It was supposed to rescue villainess side characters from danger and continuously improve their quality of life. But... In the first mission, the side character is secretly loved by a female bodyguard, who even risks her life to save her. In the second mission, it's not just that the side character isn't upset or troubled, she's practically spoiled by the heroine into becoming helpless. In the third mission, the side character is... a lovestruck prince's concubine. The side character... Well, it may have mistaken who the side character was.
