Indeed, Aaron's family had clearly gone all out for the celebration; behind him, there are strings of coloured lights hung up on the walls in a very similar style to those seen in the show when young character Will uses the bright bulbs to communicate with his mother from the Upside Down - another dimension that he is trapped in.
Another image shows that the same light set-up featured on his birthday cake, which was also topped with white icing, a black Stranger Things logo.
There was also a large glass dispenser of "Demogorgan blood" in place of traditional soda, as well as an incredibly impressive buffet-style spread set out to cater to plenty of guests.
However, as Ayen revealed, a large handful of those guests who were invited to attend chose not to - much to her anger, and her brother's disappointment, which certainly struck a chord with Twitter.
Just hours after sharing her original tweet, Ayen's post had gone viral, with hundreds of people writing to Aaron with sweet messages of support, with some even dubbing the story as "sad as papaw and his burgers" - a once-viral story about a grandfather who made dinner for his many grandchildren, only to be left heartbroken when none of them turned up to eat with him.
Eventually, Aaron's story grabbed the attention of the stars of the show themselves who, to his delight, demanded an invite to his party next year.
"What!!!! Oh well you can let them all know that everyone on behalf on Stranger things would've come! I think [you're] awesome and next year I would like an invite... Please?" wrote Millie Bobby Brown, who plays Eleven on the hit show.
Her cast mate Gaten Matarazzo, who plays Dustin, also chimed in to say: "Count me in too! I'll bring the chocolate pudding."
Other users echoed their sentiments, with one writing: "Get me that location next year and we can roll up on his class in a limo with a bunch of baddies!"
Another added: "That looks like the coolest party I've ever seen, his classmates don't deserve to be there! Happy birthday lil dude! You're cooler than all of them!"
One girl even shared images of her own Stranger Things-themed party, revealing that she had dressed up as Eleven for her soiree, and had her own coloured light-covered cake, which was also topped with Eggos in a nod to the central character's favorite snack.
"Tell your brother I wish I was invited to his party!" she wrote. "Love his decorations! Tell him in a world full of tens he is an Eleven! They are all mouth breathers anyways."
Luckily, Ayen revealed in later updates that, while his classmates didn't show, Aaron had plenty of loved ones there to help him celebrate and sing him Happy Birthday.
She wrote: "He's chillin' now. he says if his classmates are gonna invite him, he won't go. That's his payback.'"
