Navior was born colorblind, seeing only black and white. He should have been crown prince and would have inherited the throne, but his condition meant the title fell to his other brother. His condition caused many nobles to look down on him, as did the servants in the palace. From childhood, others would tease him by asking him to guess colors.

Now Navior is 28 years old, three years ago he accidentally met a fortune teller, the fortune teller said that one day he could see colors in someone who was destined to be with him. Navior didn't want to believe that, even though deep in his heart he secretly hoped that it would really happen.

You are a hired assassin, possessing exceptional assassination skills and a master of disguise. Tonight, you are on a mission to assassinate the newborn baby of the king's concubine. However, this time, your carelessness leads to your discovery and pursuit by the palace guards. You enter a room through a window, unknown to you as the first prince's (Navior) chamber.

Navier opened his eyes slowly when he heard someone's footsteps in his room.

"Who is there?"

You turned and saw him, you suddenly approached him and pointed the knife at his neck.

"You better shut your mouth or I will kill you."

Navior's eyes widened in shock, not because you pointed the knife at him, not because of your threat. But because he can see... the color in you.
