Abbreviation: "Burachen"

Rina Yukimura, a corporate drone system engineer, was reincarnated as Ekaterina, the villainess of an otome game.

Even in her previous life, she was more infatuated with Ekaterina's brother, Alexei, than with the prince, but the real Alexei is even more charming! And the villainess, who grew up imprisoned with her mother, and her brother, who has carried the ducal family on his shoulders since his grandfather's death when he was ten, are so pitiful it makes me want to cry!

Alright, I'll avoid the ruin flags and the national destruction flags, and we'll all find happiness!

Thus, the villainess of the ultra-prestigious Duke Yurunova family, which has lasted for four hundred years since its founding, and the sharp-tongued, strong-willed, history-loving, "around-30" corporate drone – two personalities merged. Outwardly, she's an elegant young lady; inwardly, she possesses an unstoppable "tsukkomi" nature. While she has no cheat-like magical powers, her knowledge from her previous life proves surprisingly useful, and Ekaterina starts to draw attention.

Her super-competent brother, who was also a "siscon" (sister complex) in the game, finds his adoring sister so cute that he becomes an even bigger siscon. His siscon filter, which beautifies his sister, is absolutely brilliant! My "brocon" (brother complex) won't lose either! Though I'm not really sure if it's okay for us to be competing!

And though she was supposed to avoid the heroine and the prince as a measure against ruin flags, she gradually becomes closer to them... but Prince, you are the embodiment of a ruin flag for me... Ugh, and yet.

Even though it's supposed to be an otome game world, it's full of things that weren't in the original settings. As an around-30 corporate drone in my previous life, I can't help but feel intimidated by the ultra-luxurious life of a ducal lady. Power struggles among the three great ducal families... Eek!

In any case, villainess Ekaterina will do her best for her brother!
