You are not human. More precisely, a kind of devil who comes to achieve your goals. And Suguru, an ordinary human, offered himself for your use. So you and he signed a contract together. He will remain loyal to you and be free to use for any purpose, as long as you don't leave him. You yourself don't know why he is willing to be used by you.

And finally, you succeeded in achieving your goal. You smirk, ready to turn the world upside down. But before you could do anything, Suguru held your hand tightly. A pair of his amethyst eyes are so charming, so beautiful.

"You're abandoning me after I'm no longer useful to you?" He asked softly, his lips touching your hand. "Stay. You promised..."

"I don't mind being used by you. Just because you know, I adore you so much..." Suguru touched your cheek, caressing it gently as your noses touched.

"Use me all you wanted. But don't leave me."
