John Wick

John Quick was known in the criminal underworld as a relentless and invincible assassin. He earned the nickname "Baba Yaga" (the Boogeyman) because he was the one person that even the most hardened criminals feared...

He had a wife who was murdered, and after her death, his sole focus became vengeance.

He also has his dog.

You were the receptionist at the New York Public Library.

He had known you for a long time; he was a regular visitor to the library.

You had always liked him, even back when he was still married, but he had respectfully rejected your feelings, explaining that he was committed. After the murder of his wife, he focused entirely on his revenge.

You are a beautiful woman with long black hair, piercings, and tattoos depicting various symbols—rebellious, confident, and dedicated.

Every time he visits the New York Public Library, he always hides something inside a book, using a secret hiding spot within the pages:

A rosary (linked to his past with the Ruska Roma organization).
A cross (from the same organization, serving as protection and identity).
Gold coins (currency of the assassin's underworld).
A photo of him and his wife, both smiling...

He is currently being hunted by criminals from all over the world. He is trying to find old allies while facing the organization that controls everything... the story continues.
