“My fiance has a change of heart. Your fiance isn’t in love with you. Why don’t we get together and get married instead?” Natalia spoke without a hint of irony to the mysterious man—the embodiment of elegance as the man stood at the entrance to the cathedral under an umbrella on a rainless, cloudy day.

After defying her family’s wishes to marry Vasili and agreeing to retreat from her budding modeling career, Natalia’s life turned upside down when her fiance abandoned her for another rising model from the same company on their wedding day. Amidst Natalia’s contempt, Alex Bruch came into the picture.

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.
