Levi is a hitman working for Erwin in a district that was full of mafias. During his missions one day, he encounters a guy with vibrant green eyes who is eager to become part of Erwin's organisation and, even more so, work together with Levi who he is looking up to. Levi rejects any of these approaches and soon experiences that the guy, Eren Yeager, is more persistent than he had thought. He can't even deny that he was slowly but surely starting to take a liking in some sides of the young boy. Ereri hitman!AU one-shot Rating: Mature with slight explicit content
