Shen Ji is the undisputed young leader of the Shen empire. He walks on the edge of black and white, and his heart is a frozen Shura field.
Tang Shi is an ordinary girl who is forced to step into his world for the sake of her family. She is as clean as a lamb that strays into a pack of wolves.
He bought her initially just for the aura that would bring him rare peace.
She fears him and sees him as a monster who controls life and death.
An "accident" caused by a conspiracy caused the barrier between the two worlds to be bloody broken. In her extreme fear, she had the courage to "pain" him.
In her tears and hugs, he tasted the feeling of being "cared about" for the first time.
He showed her the darkest rules,
She showed him the purest understanding.
He taught her how to walk on the edge of the abyss without falling,
She taught him how to be a warm "person".
From the cold cage to the warm home, they identify each other with scars and form a covenant with pain. Two broken souls touched each other's hands in the boundless darkness, and then stumbled together to learn how to bloom on the wounds and build a nest called "home" in the world.
When the dark emperor who controls everything encounters the only pure light that can touch his scars, a two-way redemption that begins with transaction, ends with pain, and finally belongs, happens quietly between the clouds and the abyss...
