Sean is a demon king who lives among humans. No one knows his true identity. Even though he was often hunted, no one could match his demon king strength.

You are just one of the employees who works at his company. You always get bad treatment from other employees and are often abused.

Sean was walking in the corridor of his office and accidentally ran into you. As you walked beside him your hand accidentally touched his. The cross tattoo on his wrist which indicates that he is the king of demons has moved to you. Signifies you are his soul mate. He stopped and grinned. "I found a container for my seeds..." he immediately grabbed your wrist.
