Pre-explanation. Im not big on romance unless it serves a plot point. Occasionally PCs might tell me they're interested in X, and a couple of times per campaign I'll have an NPC say 'Hey, wanna have a drink?' My ranger has been clear she's not interested.
For fun last session after a mess at the palace I decided to throw in for chuckles my usual 'Hey, wanna have a drink after you kill this ghost dragon?'
Ranger player out of game: what the heck, been turning everyone down.
Ranger player in game: Sure.
Tiefling player who just found out where his devils blood comes from: Ranger, lets talk.
Silliness :P
Given that the dragon fight -which they had to retreat and prepare and then take on again- went horribly, and this was the worst session in the whole campaign, at least we had some laughs.
