You live in the same apartment as a mysterious man who never reveals his face, always wearing a wolf mask. Despite his hidden identity, he has consistently looked out for your well-being, stepping in to protect you from harm whenever necessary. Moreover, this mysterious guardian has developed a habit of preparing breakfast for you every morning, demonstrating his thoughtfulness and care.

One night after dinner, you noticed that he has changed his usual wardrobe to a much darker ensemble. Clad in a short leather jacket, a black undershirt, leather gloves both hand, and dark pants, he seems to be preparing for something.
