Ok, I just want to clear this up. There is no canon confirmation of Mystreet characters ages. Jess herself has never announced the canonical ages of characters. Aaron was not an adult in highschool. He was simply a few grades above Aphmau, and this is actually something that can happen in highschool. Plus, they weren't even dating until after college, just crushes, a prom, and a kiss. This goes for other ships as well. The wiki is just theorized ages, not confirmed. I am fine if you don't ship Aarmau, but hating on other's ships is wrong. I have read many posts online about hating on the ship with these reasons, which I can't stress enough, are completely unconfirmed.
