I'm trying to find a story. it was a Harry Potter fanfic. Harry Potter Severus Snape slash. Snape was an Addam's. Harry and Snape were getting married. Harry was cursed with I believe it was the thousand knives curse. Snape had a tumor. they did this really weird ritual with piranhas when they got married ended up with a stone in their chest. I'm not sure if it was officially put in a crossover or not. but I want to reread it since it's been so long since I have. I tried looking for it for myself but I cannot find it.
