The time of Joseon was around 1797.

So Hyun lost her desire to live. Yet, life needs more from her. She lost her memory and experienced passionate feelings for her stepbrother, Yong-chal, without knowing the significance of love.

She doesn't know about the way that the attractive prince, Shi Hwang, became hopelessly enamoured with her from the beginning. She isn't typical intellectually, yet both men are frantically enamoured with her.

In the wake of meeting So Hyun, the attractive Shi Hwang felt love. He'd never been close to another lady before, so he'd gone out of his way to get close to her.He even turned into a king when he never wished to become one. He paid a lot to keep her close by. Struggling to get her attention keeps him awake at night.

She was fortunate to be cherished by a mysterious man who entered her life unaware of her real identity.

So Hyun finds the bits of her memory in which she has an obscure lover, a puzzling man who generally safeguarded her in difficult situations. She doesn't see him around, yet he is near her like a shadow.
