Ok, I say PCs... but I actually mean PC.
I am running a 1-player D&D 5e game for a friend (let's call her Jane), as a way of introducing them to the game. It was only meant to be a "non-canon", one-time-adventure that was supposed to peter out when the actual game started, (we are both PCs in the actual game, that is run by a different DM, with additional players). However, Jane spoke with the DM, and they decided that my game would be part of the characters' backstories.
I was fine with this at first, and I have a storyline to follow, that will eventually end in a way that doesn't affect the actual story of the main game.
For reference, the PC's name is "Cass".
So the story arc I made was:
- Cass' father (an "evil" king, from her backstory) wants to bring her back home after she ran away.
- Enter Big Bad Guy - objective: Bring Cass home. The party has a run-in, and only barely escape with their lives.
- Now the party need to turn the tables, find the Big Bad Guy before they find the party.
- Kill the Big Bad Guy.
Pretty simple, just to keep things short. However, Jane has decided to develop a love interest between the PC's (which I decided to entertain at first), after my PC saved hers, but it has now gotten out of hand, so much so that she has completely abandoned the storyline, to focus purely on the relationship.
It has arrived at the point where I no longer want to run the game, because it has turned into some kind of weird third-person sexting adventure more than anything.
Yes, I do have an interest in Jane, but I don't want to bring that into the game as well. The game is becoming a hassle, because I don't want this to be what it has become, and I'm not sure how I can bring the focus back to the storyline. I want to finish the game, and get back to the actual game that is being run for the larger group.
I have spoken to her about this issue more than once, and she does agree that it is taking away from the story development. I have then tried to continue the plot, but every time I do, she always brings it back to the love interest. Every time I have spoken to her about it, she has said that she agrees that the story is not developing, and she sounds like she's sincere about trying to restrain herself, but I have not seen any change in that direction. So I really don't feel she has any real issue with it.
(We do have something going on the outside the game romantically, so there's no need for it during the game that I can see.)
So my only real option seems to be to alter the story in some way to change her focus. How can I get this game back on track? What kind of simple plot hook, twist or in-game device can I introduce to bring Jane's focus back to the story?
