Midnight; a GOT7 Gang!AU

Warning; mentions and use of drugs, violence, drinking, and cursing

Midnight, the underground city beneath Shanghai, China. Many gangs, criminals, and illegals reside here. There's only one way in and out but only the citizens of Midnight know where it is. Although, there's one catch.
No one can leave once they've been brought to Midnight; that is, except for the Red Dragons.
