I talked to @damnchou about an AU last night where Erwin has a youtube channel and makes videos about super boring historical war related stuff there (tactics, battles, etc.) It really only serves a niche and he has only a few followers, like 300 but hes bein all nerdy over there

Levi is bored and clicks a recommended video by erwin and is like "Holy shit this is boring as fuck but will you look at those arms". So he spends an afternoon watching Erwin's videos on WWI strategies or whatever and he's like "Omg I wanna end this but hes so hot I cant stop"

One day Erwin crosses his path and Levi just blurts out "Shit youre hot boring war guy!" and Erwin's like "Excuse me?" and they start talking and Erwin is really happy to meet someone who actually watches his videos. Everything goes really well until Levi introduces himself as

"Levi. Levi Ackermann."

One night while he was drunk and horny he watched his favourite video where Erwin wears a tight shirt and gets up at some point to adjust the curtains so you could see his ass. He commented "Hey Blondie, how big is your dick?"

His youtube name is the one from his google account, he only made the account to follow Erwin anyway and he only ever wrote that one comment. And Erwin reads all of the about 5 comments on every video (he often leads heated discussions with other history enthusiasts).

So when Levi introduces himself he KNOWS and he's like: "So...do you still want to know how big my dick is, LeviAckerman32?" And Levi who NEVER blushes goes red like a tomatoe bc he only remembered masturbating to the video BUT NOT COMMENTING ON IT.

And Erwin just laughs the most beautiful booming laugh Levi has ever heard, his blue blue eyes crinkle and his hair falls into his forehead and Levi knows hes utterly fucked.

When theyve been dating for a while Erwin asks: "Did you ever...you know...do smth while you watched my videos?"
"That video about those war tactics during 30 Years' War? I came so hard I had cum on my forehead."
