I was reincarnated into an otome game world, becoming Lady Giselle.

The sickly older sister of the villainess—in short, a background character.

The biggest problem is that this background character dies in most routes.

If I don't discipline—or rather, re-educate—my younger sister, who is the cause of my death and downfall, I'll face a dead end at 19!

I'm fine with being a background character; I just don't want to die.
