Reincarnation

Male lead, why are you proposing to the villainess and not the heroine? Having the strongest man in the empire as her father, the most beautiful woman as her mother, and three arrogant brothers, she had immense beauty, power, and irreducible wealth. I came to possess the villainess who had all these things in a romance novel; “Cielle Valentine.” In the original novel, the heroine was the adopted sister of Cielle, who had an unrequited love for the prince who loved her sister. Blinded by jealousy, Cielle harassed the heroine and was consequently executed by the male lead. Being jealous and tormenting others caused my downfall, so I tried to matchmake my sister and the male lead... “Please marry me, Lady Cielle.” Male lead, why are you proposing to me?

"Wait, am I… a squirrel? How, when, why?!" I opened my eyes and found myself… as a squirrel. Not just any squirrel, but a divine beast known as the "Sacred Squirrel," treasured for its ability to soothe a wizard's magical power. But hold on—I was human! To return to my human form, I need to steadily accumulate magical energy.

Scarlett Arman is no ordinary lady, not just because she’s engaged to the emperor. Newly reincarnated as a character in a fantasy novel, Scarlett knows she is supposed to die a horrible death at the hands of her fiancé, Charleon Kalior. Determined to escape her fate, Scarlett decides to make Charleon break off the engagement... But why does he keep wanting to spend time with her?!

[Reincarnated into a novel I loved when I was alive.] Too cliché, you say? Think again! Because that novel… is a 19+ dark fantasy story! Reinatis is reborn as the younger sister of the beautiful and kind female lead, but when she can't bear to watch her sister suffer a tragic ending, she takes her place— and ends up captured by the insanely handsome and utterly mad male lead, Theodore. But wait... this guy... he's just an madman, isn't he?! "Okay, sure, I do have a thing for beastly men… but I wasn’t asking for an actual beast!" Thus begins the tale of female lead brighter than sunlight… taming her beast (of a man).
