Sunny Suzuki and the Stupid Traitorous Rat by BubbleHubble13

Summary
When Sunny trips down the stairs and spirals to the floor, he thinks he's dead. But instead of hitting the ground and crumbling from gravity, he passes right through the wood, right through his own world, and wakes up in a new one, in his 13-year-old body.
After seeing enough witches in hats, wizards with wands, and all-too-familiar faces, he falls to one horrible conclusion: he isn't dead after all. Instead, it seemed that whatever happened to him sent him straight into the magical world of Harry Potter, Mari’s favorite fictional story.
Sunny only has four goals. Everything else was secondary and unnecessary.
He had to stop Pettigrew, protect Harry, stay secret, and above all: go home.
…with how things were going so far, he might only be able to do one of them.

Harry was used to having odd school years. He truly was. But this time things were getting odder much faster than usual. For one, Sirius Black was out to kill him. Two, he spelled Marge into a balloon in the summer. And three, Hogwarts gained a very quaint new student who seemed to be terrified of him.
One normal year. That’s all he could ever ask for. But Harry never got the things he wanted now, did he?

Harry Potter and the Crushing Responsibility of being a Fate-Appointed Therapist by BubbleHubble13

Summary
Harry foolishly expected his retirement at the ripe age of 17 to be calm. Perhaps a few vacations to the beach, travel the world, see new things now that death wasn’t knocking on his door every other year.
A mistake with a Portkey travel proved this illusion wrong very, very quickly.
Suddenly he was trapped inside a house whose magical wards didn't allow him to leave on his own, with a strange mute(?) boy who was convinced he wasn’t real, and, oh, to make matters worse, he somehow lost his wand in the trip. He was also getting the oddest dreams of a colourful world with a monochrome child, and as strange as that was, it hardly made it to the top ten of his list of concerns.
All in all, this was too bizarre to be a fluke. Experience told him he must’ve been sent here for a reason. Now all he had to do was figure out what that was.
Meanwhile, Sunny's half-there conscience had no idea why, out all possible hallucinations to have while awake to such a painfully detailed degree, his brain landed on Harry freaking Potter. And no, Harry, he didn't know how to "turn off the wards" of his house, whatever that was supposed to mean. Just let him go back to sleep!

Summary
|Squid Game AU|
Summer of 2020, the infamous Games occurred in South Korea. Full of death, blood, betrayal, the epitome of human beastiality captured in childish pastimes- the VIPs however, rich in everything but sensation, aren’t satisfied with just one game a year.
Winter of 2020. Nestled within some off-shore island in the west coast of the United States of America, more games take place.
Nine years ago, Mari fell down the stairs. She didn't die this time. Basil still panicked, Sunny still lied. As the words “comatose” and “uncertain prognosis” sunk into reality, the friend group broke apart just like before, only in different ways and for different reasons. A crack in the course of their picture-perfect lives, one that splintered and grew over the years, never fixed.
Medical bills, student loans, gambling mistakes, bad addictions and family debt.
So many ways a life could crumble.
One minute, they were given a card by the sinister Salesman. Three symbols on its back. Circle. Triangle. Square. The next, Sunny, Hero, Kel, Aubrey, and Basil woke up in a metal-framed bed wearing numbered clothing. Each had a reason to leave. Each had more reasons to play.
Let the games begin.
