Promos that need to be serialized

I’m Selena, a daughter born to a family well-known for their fertile women. I was all but sold off in a marriage to a sickly duke whose life hung in the balance, all for the sake of producing an heir for his family. They provided me a medicine purported to aid in pregnancy, and the astrologist advised me good days for sleeping together, but... there was no child.

Betraying my tyrant elder brother by helping the abducted male protagonist to escape, I was just a short-lived insect in a supporting role.

In the original story, I was bewitched to help the male protagonist escape…
Original? Who cares about that? First of all, I would not live if I did it.

So I decided to talk with the unfamiliar scary elder brother whom I never know when he would kill me. I mean, I tried…

“You dare to touch my younger sister without fear, take responsibi

“This bitch is not my daughter.”

Ariel was born in the Marquis family but she was abused and abandoned by them. She ended up a miserable death filled with endless misfortune. When she woke up, she was nine years old again. In order to not repeat the miserable life, Ariel decides to have a contractual marriage with the son of the grand duke, Lakatyer, who is famous for blood and madness.

“But I just married yesterday…”

I lived suffering without a home, religion, or parents, but an angel appeared and reincarnated me.

I reincarnated because he said I would have a (handsome) dad and a (handsome) older brother who would spoon feed me, and even gift me a diamond mine, but...

I might be a child from my mother's affair?

“Did you hear? The House of Grand Duke Vailot came to sponsor an orphan.”

To find a way to live, I threw myself at the villain's family, the Grand Duke’s, and-

“You can do whatever you want. I, as the Grand Duke, will protect you.”

“You’re not an orphan. You’re my younger sister.”

Why do they love me?

Just as I made up my mind to live well since I'd already become a lady of the House of Grand Duke Vailot...

I possessed a supporting character in a reverse harem novel.

As a young concubine who gained the interest of the emperor. The concubines, the male lords, eventually killed her for treason.

Fortunately, I possessed her just as she was entering the Imperial Palace. Everyone in the Imperial Palace was wary of me, but didn't hate me yet. I don't need, nor do I want to be loved by the emperor.

"Come to my room tonight. I'll read you a fairy tale!"
'Woo, don't
