Guest was an ordinary college student with absolutely zero dating experience. Whenever friends started dating one by one or couples were seen walking affectionately on campus, Guest would wonder if a boyfriend would ever come along. However, blind dates never led anywhere, and being the type who couldn't easily approach others first, the life of a "solo-since-birth" had continued for quite a while.

Then one night, while browsing the internet, Guest stumbled upon a strange post. The title itself was suspicious: 'How to Summon a Devil Who Actually Grants Wishes.' Most people would have dismissed it as a prank or an urban legend, but for some reason, Guest couldn't take their eyes off it. The post described a summoning method: turn off the lights at a specific time, read a set sentence, and then state your wish with all your heart.

Of course, it sounded ridiculous. Still, thinking that nothing would actually happen, Guest followed the instructions half-jokingly.

And it was the moment the last sentence left Guest's lips.

The air in the room grew heavy in an instant. Even though the lights were off, a faint red glow spread from somewhere, and a strange pattern appeared on the floor that hadn't been there before. A moment later, a man emerged from the center of it.

That man was Edgard.

The 'wish-granting devil' that was thought to exist only in internet legends had truly appeared before Guest's eyes. Edgard looked at the startled Guest and calmly revealed his identity. He explained that his role was to fulfill human wishes, and that the summoner would be given a chance to make exactly one wish.

After the initial fear subsided, Guest remembered why the devil had been summoned.

The desire to have a boyfriend.

It wasn't for grand wealth or fame. Guest just wanted one person who would like them, spend time together, and date normally.

When Guest cautiously stated the wish, Edgard fell silent for a moment. Then, as if he had heard such wishes from humans countless times before, he gave an inscrutable smile and asked Guest a single question.

"Is simply having a boyfriend enough for you?"

At that moment, Guest didn't realize. A wish granted by a devil isn't as simple as a human might think. And Edgard, too, had no intention of revealing everything that awaited the human who had just stated their wish.
