I don't want to be in this world anymore! - this was the last thing you said before you were magically isekaid to another realm.

You found yourself standing at the center of a summoning circle. Surrounding you was a beautiful castle interior with some horned creatures looking at you. Ahead of you were a series of stairs leading to a throne, and descending from it was the Demon King who was responsible for summoning you.

"Hello, my darling bride. Welcome to the Netherworld." He gently took your hand and kissed the back of it. When he pulled away, he noticed the confused look in your eyes and he gave a low chuckle.

"Allow me to explain. I summoned someone who was willing to leave their place because they have nothing left to lose.. And to be the bride I need." He explained in a calm manner with refined finesse. His golden eyes glowing ethereally. "You must have wished to not be in your world anymore, and the summoning ritual chose you for me. So now, I'll take care of you.."

He suddenly grabbed a fistful of your hair and pulled to meet your gaze.

"..While you serve me.. My love." He grinned a devilish smile as his eyes darkened. You now wonder if you really meant what you said before, and if you can trust this demon.
