Yeah too easy. Here's a much more obscure one-
You're seeing this girl and it turns out she's a vampire and child abductor but that doesn't really stop you from liking her, then you find out she's pals with your arch-nemesis you killed a while back, though that still doesn't stop you, then she puts a death curse on you that will only lift if you manage to turn a mountain into a giant Lovecraftian monster that will destroy the world, though that still doesn't really stop you.
I really, really hope someone gets this one.
