Trading Husbands: My Sister Wants Mine

My younger sister, Rosalie White, and I are twin mermaids, born with the divine gift of bearing sacred beasts.

On the day we come of age, Father presents us with all the unmarried princes of the beast clans.

Rosalie picks Charles Summer, the powerful prince of the zilant clan, in hopes of birthing a sacred beast and claiming the beast throne.

However, her five babies are all dark, frail half-zilants of the lowest rank.

I, with my weak and sickly body, join with Jasper Warren of the serpent clan, the most despised of them all. I end up succeeding in giving birth to a sacred beast hatchling.

On the day of the coronation, Rosalie refuses to accept it. She strangles my hatchling and rips out my beast core. Then, she throws our bodies into the beast furnace, destroying us completely.

After my reincarnation, I see Rosalie pointing at Jasper and says, "I only want him."

I chuckle coldly. I'd like to see if she can bear a sacred beast in this lifetime.

She looked at me with a challenging gaze, as if confident that once she chose Jasper, she would be able to give birth to a sacred beast and take the beast throne.

Ten thousand years ago, a great war broke out among the beast clans. The only sacred beast sacrificed itself for the lives of countless others.

Since then, its bloodline withered away, and no sacred beasts had been born.

And now, Rosalie and I were the only hope of bearing one.

It had been declared throughout the beast clans that whoever gave birth to a sacred beast would be crowned as beast king.

In my previous life, on our coming-of-age day, Rosalie was the first to pick Charles Summer, the prince of the zilant clan. She was hoping to give birth to a sacred beast and claim the throne.

Upon seeing that she had made her choice, the remaining princes of the beast clans walked away. None of them were even bothered with me, a weak and sickly mermaid.

I could only choose the infamous Jasper Warren from the serpent clan. For that, I was even mocked by Rosalie, saying we were truly a perfect match in disgrace.

That year, we became pregnant together. She carried five, while I had only one pitiful child.

A year later, Rosalie gave birth to five half-zilants of the lowest rank. Meanwhile, my only child turned out to be a rare sacred beast hatchling.

All beast clans rejoiced and proclaimed me the beast king.

On the day of the coronation, Rosalie, reluctant to accept it, strangled my
