Bruises And Bitemarks

Leon has always lived his life in routine; wake up, go to work, get done what needs to be done, go home, then sleep. Wash, rinse and repeat. But one day, his friend Gloria convinced him to go to a local bar with his other coworkers.
Of course, he thought that it'll just be another annoying night out with a bunch of drunk people. And it was, well, until a murder spree brakes out in said bar and he finds himself in someone 's bed.
