Reincarnated as the Demon King's Daughter

Basically those romance/betrayal Chinese novels, Isekai Japanese novels, and reborn as __ 's daughter Korean novels all bunched up together. Gone ̶y̶a̶n̶d̶e̶r̶e̶ Wrong

Title kinda misleading sorry.

Betrayed by her best friend and younger sister, ignored by her parents. This was Marianne's fate. No matter how hard she tried, no one appreciated it. Slowly, her dreams were shattered. Eventually, the worst happened. Never did she expect this.

Slowly opening her eyes, was an unfamiliar place. Or should I say world? She remember her last words clearly, "I SWEAR I'LL KILL YOU!". But how? She knew nothing of this world and even if she did, she was the only one who transmigrated.

"Sol" It was then, someone finally appreciated her existence. If only this moment would last. Reborn as Princess Solaris El Noctis, the daughter of the Demon King. Will her life be another misfortune again?

All credit of the cover goes to whoever made it. I do not claim it as my own.
