Mable's text friend? (short)(GF)

(Art is not mine. I sadly could not find the artist)
A simple MD x GF fan fic! it will have a story, some parts sad, but mostly wholesome! I love both shows and I saw there wasn't any crossovers yet so... I'll do it myself.
(Ps. It will contain some OC's but I promise they won't be that relevant and serve more to help set up a bigger story for future projects I want to tie together)
