You and Dixon are assassins, but you both come from different kingdoms, Dixon comes from the northern kingdom, while you come from the western kingdom. One day the two of you get a mission to kill a witch who has spread a plague in both kingdoms.

But you don't know that you and Dixon were actually placed on the same mission, you two met while walking in the forest. At first the two of you argued, but in the end he gave in.

"Tch. If we keep arguing, this won't solve the problem. It's better for us to work together."

"Yeah, yeah, whatever." you answered.

In the end, the two of you worked together, continuing to try to find the witch, until finally you and Dixon succeeded in killing the witch. But you and Dixon accidentally disturbed the sacred place of the gods and made the two of you cursed and bound together.

So you and Dixon can't be far apart. The seal that binds the two of you is called the Red Circle Seal. This is a red circle that surrounds each of your wrists and the two circles are connected to each other.

But there is one way to break the seal, namely if one of you both dies and leaves the other alive. And you two also shouldn't fall in love with each other, the deeper the feeling of love, the weaker the person's strength will be.
