So. This is a Lynncisco idea. Yeah. If you don't know what that ship is is, I don't blame you.
It's a very underrated ship.
Anyway. The story goes like this. Lucy takes Lynn to the cemetery to see if they can see some spirits. And what do you know, they meet a lot of spirits. This could have potential to reference tv, movie, anime characters or famous people that have passed on. Anyway, while they are there, Lynn meets with a spirit who calls himself Francisco. Lynn talks with him until she leaves, promising she'll be back. Every time she goes back, she slowly falls for him. Once they become a thing, a few chapters could be them going on dates and things.
How it ends is easy. It ends with a very old Lynn on her deathbed passing away and becoming a ghost. After she realizes she's dead, she runs to the cemetery and goes to meet Fran. They meet, kiss, and that's where it ends.
So, what do you think?
