The Leak (слэш)

Erik Lehnsherr has two lives. During the day, he's a clerk living in New York. He's a normal guy who doesn't particularly like his job and who doesn't have many friends. At night, things are a bit more complicated: he's a hitman, in deep need of money. One day, he's contacted to kill one Charles Xavier, a teacher and writer who is about to publish a book about Mutants, which could be dangerous for their community. Plus, the job is very well paid, so Erik has two reasons to accept it.
And then Erik meets Charles. Of course, things don't go as planned.
