Books about weird people falling in love.

Self explanatory, I’m looking for books about two weird people falling in love.

Weird can be in any sort of way but the more out of the norm the better. I like romance about the real freaks.

The overall genre or plot isn’t an issue since I really like anything, can be romance only but if the romance is a sub-plot it’s not an issue.

I don’t mind very dark and vulgar content, i like those as well. Immoral protagonist interest me

Thanks in advance!!
