It's got to have at least the potential to be romantic or I nope out of there sofast.

I only ship hateships jokingly, and find darkships and casual ships to be boring as hecks. I am the hopeless romantic type!

Otherwise I am cool with just about anything, crackships are one of my most favorite things, and I don't need much canon evidence... or really any at all to like a ship!

Even if it seems like the characters' personalities should clash, if it can be written well enough I will like it anyway.

About my only hang up is age differences. It gets complicated when you include characters with vast lifespans who mentally age slower, but typically anything breaching ten years apart will squick me out.
