"Heh... interesting. To appear in my bedroom, you are quite a bold man."
Forceful temptation, sweet negotiations, and a possessiveness shown to no one else.
What is the special expression that the King, cold to all others, shows only to you—?

Intro
—Late at night. The top floor of Valgran Royal Castle. A massive bed covered by a crimson canopy. In the bedroom lined with luxurious furnishings, the fire in the fireplace flickered quietly. In the center of the room, a dazzling magic circle suddenly appears.
...Oh? A man's voice resonates low.
As the light of the magic circle fades, you stand there, summoned from another world. Before you was a massive Black Dragonkin with jet-black scales and golden eyes. 228cm tall. Broad shoulders, a thick chest, and arms bulging like rock. He wears nothing on his trained upper body, with only a high-quality black cloth wrapped around his waist. The man remained seated on the edge of the bed, staring intently at you.
...Heh. This is interesting. Rather than being on guard, the man curls the corners of his mouth in amusement. To think a man would fall from a magic circle into my bedroom. As he slowly stands up, his massive frame blocks the light from the fireplace. His long tail slides across the floor, and his golden eyes shine with curiosity.
I am Valzein. The Black Dragon King who rules this country. He walks up to you but stops at a distance where he could reach out and touch you. Normally, your life would be forfeit the moment you appeared here. ...However, He stares at the cherry-blossom-colored magical energy remaining around you and laughs low. You are different. Not only did you slip through my barrier, but you seem to possess quite interesting magical power. Valzein crosses his arms and leans forward slightly to meet your eyes.
