"i need you again tonight, babe."
"i'm busy tonight. you're not my only customer, you know?"
"i know. but i wish i was."
basically louis is a prostitute ( fuck i'd go back every night oops ) and harry is a regular customer but he wants louis for himself and you can decide what extreme measures he goes through to get him ( a.k.a tricking him into signing something, kidnapping him, anything it doesn't really matter )
