Curiosity killed the cat (ziall au)

They say curiosity killed the cat, but what they don know is that saying is unfinished.
When Niall Horan a 17 year old boy, or as he says man, is walking the streets of Bradford he sees two men, one is beautiful with charcoal black hair in a quiff, with honey eyes, olive skin, and many tattoos that hold stories, the other man has a stubble, a bit heavy and very intimidating with tattoos covering nearly every part of his body, the older man grabs the beautiful and obvious younger lad and pulls him into a the alley, Niall being the curious little shit he is follows them for 'safety reasons' but really wanted to make sure the beautiful nameless man is unharmed.
Zayn Malik a 23 year old man trying to quit the drug dealing business but when he goes to meet with Tom his boss he asks to quit, but lets just say things don't go as planned, Zayn is pulled into an alley but not before looking at the blonde lad that was obviously watching them.
