Ilse, the protagonist, was born into an impoverished marquis family.

She realized she had been reincarnated into the role of the villainess in an otome game she had played in her previous life.

Not having enough free time to bother bullying the heroine, she left her alone, but for some reason, the heroine kept bothering her excessively.

It seemed the heroine was determined to cast Ilse in the villainess role, no matter what.

Ilse already disliked her type of woman, and these days she found it increasingly irritating to have her forced into her line of sight.

And when her fiancé was taken, Ilse's patience finally snapped.

"If you insist I'm the mastermind behind this bullying, then I shall fulfill that role completely."

Ilse, together with her childhood friend and attendant, Joshua, decided to directly accept the heroine's challenge.

This is a heartwarming story where a cool beauty protagonist subtly retaliates with sarcasm and mockery against an overtly cute and air-headed heroine.

While there are occasional light acts of comeuppance, the main focus is intended to be romance.

*Please note: The protagonist has a moderately bad personality and sharp tongue.

*Please note: The heroine (not the protagonist) does not possess memories of a past life.
