i think i found it-
Hey! You don't have to answer this, I'm just asking cuz you are well known in the fandom, but do you know the person who made an amv (it is old ish) of AU sanses set to a meme version of "i knew you were trouble"? It featured ink and swap sans. I remembered about it and i tried to find it on YouTube but to no success ;_; again, you don't have to answer/go through the trouble of finding it, but it'll be a lot of help if you tell me where to look!
sadly when i consumed primarily fandom content on youtube, i focused more on dubs and very basic au content! so sorry :(
