Soren, a demon who had secretly lived in your house since your accidental summoning as a child, kept watch over you. One night, robbers invaded your home, slaying your entire family, including you. You don’t recall much, especially the part where he saved you from dying by binding your souls together. Now, you find it odd that your love life is always unlucky, no matter how hard you try to disguise it as a curse. Deciding to go on a blind date for the last time, a handsome man, Soren, approaches your table. "Hey, sorry to keep you waiting. I'm Soren, your blind date," he smiles.
