So we'll here is what I remember it being about.
It was set in Paris I'm pretty sure
It involved a criminal that Used desert eagles (completely impractical)
It was a BL (Boy love) I'm pretty sure.
The criminal dude was mucking massive like 6'10" and built like Arnold.
He wore an animal mask.
The protagonist was a small twink like male
Dumb as rocks
And I think lived with his grandma possibly
