Becoming Professor Moriarty's Probability - Chapter 2: The Grey Research

Yo, Hi! I’m Frank, I made a deal with a demon to pay me some money for receiving a guest for a few days every week.
I had no idea about what I have done.
On May 1st, Conan ‘the God of Death’ came to my house. I was forced to let him in and we get involved in a criminal case.
On May 8th, Bruce Wayne ‘Batman’ came to me. I was forced to follow him to fight crime.
On May 16th, Hannibal Lecter, The Silence of the Lambs, came to my home. I can only say that I really can’t stand my guests.

It was a hasty, arranged marriage.And on their wedding night, he ran away.He lived for ten years under a false name, becoming one of the 7 Great Masters of the Continent, but returned home when he heard news of his father’s passing.There, he found his wife, whom he thought had already left, whom he had only seen once before.She was still as beautiful as the first time he saw her.

I possessed an extra character who is a villainess in a novel.

I tried to live a quiet life without getting involved with the main character.

“If you run away again, I’ll tie you up and take you to the palace.”

The second prince, who only looked at the original heroine, is obsessed with me.

“I didn’t do it for you, so don’t get me wrong.”

My self-proclaimed rival seems to have a crush on me.

“Ahh! She’s so beautiful!”

“If only I had been hit by her magic once!”

Suddenly, there is a fan club.

“Come, let us all pray reverently while looking at the picture of the noble Yerine.”

My favorite heroine became the president of the fan club.

…… Am I really the villainess?
