A Bellicose Lady Got Reincarnated!? ~It's an Impossibly Hard Game Where I Would Die If I Don't Fall in Love

Is this truly the world of a game? If I fail to romance one of the yanderes, I will die! Before my reincarnation, I was a top-class brawler and former delinquent known as the "Crimson Rose" or "Crimson Demon," feared and respected by peers. For me, resolving conflicts with fists came naturally, while matters of the heart were entirely foreign; consequently, my romantic skills are nonexistent. Despite this, I have been reborn as the heroine of an otome game, blessed with a noble lineage and a gentle appearance. To ensure my survival while assisting in the investigation of a mysterious incident, I must somehow navigate these dangerous romantic entanglements. Serina, an Earl’s daughter with the soul of a street fighter, remains blissfully unaware of her own charm. Cherished by those around her, she embarks on an unexpected journey to find happiness in a world where love is literally a matter of life and death.
