Fanon
Like other poly ships, EMA is popular but this currently rivals JeanSashCon, another popular poly ship, which would often cause fan wars among fans on which is the better friendship trio. Around 1/6th of all works under the ship's tag on AO3 are Modern Day AU. On AO3 it is the third most written polyamorous ship in the fandom tag, and the most written group friendship.

Those fans who don't ship the trio romantically, enjoy them as friends.
