To be honest I do think they're going to be in a relationship.
Pretty Boy worked hard you know? He won his meal and I surely doubt he's gonna leave after just once.
Playboy liked it. He won't leave him alone unless he's sure there's no way for it to be something else. He found him once you bet he'll find him again.
TL;DR they're still not done with each other. If the thing is gonna get serious or not I can't tell but this won't be their last time.
