I feel like I'm tweaking because I just remembered this one tengen uzui x reader thing I read like a year or two ago that I can't find anymore and it's driving me crazy. It was Tengen and his wives x reader who was also a demon slayer and had unlocked the demon slayer mark, and the wives and Tengen were going to celebrate reader's 25th birthday because it would be reader's last day alive and it has two endings, one where the polycule had a happy, peaceful day and one where reader died in their sleep the night before and the rest of the polycule was grieving especially hard because they were supposed to have one last day with reader...does anyone know what I'm talking about?? Has anyone else read this?? It was on Tumblr, definitely, but I forgot who wrote it and I can't find it, any and all help is appreciated please 😭
