Does the Villainess Need the Heroine's Permission to Save Herself?

Stella drove her older sister away and smugly reveled in her role as the villainess.

But after a fall awakened memories of her past life, Stella remembered everything.

Oh no! Her sister is the heroine!

It was already too late to win back her sister's affection. Stella's reputation was at rock bottom, and she was already halfway to a death ending.

No, I have to save myself!

Donning a mask and pretending to be someone else, Stella reconnects with her sister, loves her, and saves the other heroines around her who have suffered the same misfortune, all in the hope of building up enough affection to avoid death before the truth comes out.

Day one: She stays by her down-and-out sister's side and becomes her emotional support, even if she has to call it "love at first sight."

Day seven: Her sister says she's grateful and is going to prepare a gift for her. Great!

Day N: Why is her sister sneaking off with her clothes? And why is she taking them to some kind of testing organization? What if they find out!

"Della, I think you remind me of someone. Guess who?"

"Miriam, this isn't funny. Please put down the rope and the secret potion."

"Heh... Did you ask my permission before trying to save yourself, my dear little sister?~"
