She was dressed in white, with a mysterious orchid imprint on her forehead, her skin like jade is always covered with a veil. Since childhood, she had left her parents due to her special status and lived her life with her master in the clouds. She was not yet ten when her medicinal skills were renowned in the world. In order to save the people, she descended the mountains, however, she encountered a storm on the way to the epidemic area. The man who saved her would tease her for enjoyment, little did they know…

Feng slowly backed up to the door, “W—what’s up with you both?” Two tall blond men stalked closer and caged her in the corner, “Aiden, Ethan, you both are too—too close,”

‘I want to travel to a place unknown to the many…’

It was a passing wish to the weary and tired Eugene and she’d not think it’d ever come to pass… but it did.

She opened her eyes and found she was sent to a novel-like world she wrote in passing and became Jin Anika, the scorned queen notorious for her ruthlessness and undeserving of her status.

Queen Jin only sought and desired to see the destruction of this world — the villainess who met her untimely and miserable end at the hands of her husband, Kasser, the reigning king of the Fourth Kingdom.

While struggling to survive in the unknown world, King Kasser visited Eugene and demanded that a contract be fulfilled and come to fruition.

“Three years ago, we made a deal.”

It turns out the Queen was under a contractual marriage with King Kasser. The ultimate price? To bear him a child.

“A… a child?”

“Yes, my successor.”
