I need help. I read a really really really good Merthur reincarnation fanfic a few years back, in which merlin was immortal, and was waiting for arthur. and like. arthur came back. and merlin showed him everything he missed. im pretty sure it was rated M or E, i don't really remember. but in it, Merlin had a lakeshore cottage? and thats where Arthur stayed. and merlin showed him dr who and hoodies and all of these modern things. i also think it was over 10k. it was on Ao3 i forgot to mention that. Also no knights were reincarnated.
this is literally the vaguest description i am so sorry but please if someone recognizes this fic please please please help me find it
