"the long-lost twin" | alchemy os souls !

Sayan is Jang Gang's daughter and uk's twin sister, even though her father closed her gate of energy when she was born, her gate was now open because when she was 5yo, she accidentally fell of a cliff and the only way to save her was by opening her gate, so Heo Yeom was forced to open it.
After he opened her gate, she found out that she had the ability to see energy and was also able to heal wounds and minor diseases, at first it was only healing minor injuries like scratches or skin cuts but it was only the beginning.

But she was taken away from her family one year later by Jin Mu, her family searched everywhere but was never able to find her. After bringing her to Danhyanggok and introducing her to naksu, he took sayan apart and told her that all of her family were dead due to a fire, that he rescued her and also that she had to never tell naksu her true family name and origins, he said now her name would be lee sayan.

The more years passed the more she forgot her real identity and naksu and her both became powerful, but above all they became linked, they both considered each other as sisters.

But when her and naksu, who shifted her soul into mudeok's body, were brought to uk's house, sayan suddenly remembered everything...

What will happen? Will she tell uk about it? Will she stay by naksu's side? Will naksu be mad at her? Will jin mu find them again??
