Summary
Two people come out of the box, with English accents. The girl was curious, her ginger hair flicking as she turned her head, with a look of confidence. The man, on the other hand, clad in a bow tie and suspenders, seemed very confused.
"Yes. I hit something. That shouldn’t be possible; there shouldn’t be anything in the time stream, and definitely not around these parts… and definitely not…”
You clamber to your feet – clamber? No. You… slide to your feet with cool indifference – and make yourself known, interrupting them.
“Whatcha lookin’ for?”

A Touhou x Cuphead fic
I've written this thanks to the cringy depths of my mind
But I'm gonna try to make it an alright fic anyway--
While starting off his new life and stuff with a commemorative trip to one of his small group's favorite restaurants, Cagney bumped into someone who he ends up becoming attached to.
Their start might've been a bit awkward but, hey, they're both equally inexperienced with love and those of the opposite sex, so they'll be able to learn together!
--
NON-CHEESY VERSION:
Cagney and Yuuka encounter each other at a restaurant in probably one of the more awkward ways to first "introduce" yourself to someone and end up dating later on cuz they like each other.- Language:

Summary
“Izuku Midoriya you are quirkless. You are quirkless, you are my son, and you are a Midoriya. That means you are strong. It means people may not like you, but you cannot let it affect you for too long.” She combs her fingers through his hair making Izuku melt in comfort. “This world may not treat you like it should, Izuku, but that doesn’t mean you are any less. Understand?”
Izuku nods shakily, his cheeks are damp with tears and his eyes are wide with awe as he looks up to his mom. He’s four years old, but he’s always been able to understand concepts a bit quicker than his peers.
His mom kisses his nose, and wipes his tears and some snot away with her pajama sleeve. “You are a Midoriya, Izuku. That means you are strong, even if for some reason you don’t see it.”
---
Two months after Izuku is announced quirkless, him and his mom move to a sea-side town named Hasetsu. Inko hopes the move will be enough to help her baby boy.
She didn't know how big of an impact the small town would have on her baby boy.

The entire situation Arya found herself in was odd. Though, come to think of it, every moment of her life for the last decade had been either odd or miserable, so she would take odd any day. But this one was truly odd. She was familiar with the concept of holding someone hostage and interrogating them, whether humanely or otherwise.
Not elven hostages, though. This was a first.

Alternately titled in my google docs: Jaskier Is Precious Boi.
"Merlin," Jaskier begged as Yennefer continued to hit him with painful spells after painfull spells. "Merlin please help me," Jaskier said as he was yet again throw across the forest clearing into the dark evil woods. Yennifer's cackle echoed like a symphony throughout the forest.
"Who's Merlin?" She sneered at Jaskier before slicing a knife across the bard's face, "your boyfriend?" Yennifer threw Jaskier to the ground, he could taste the mud on his tongue. Jaskier sobbed silently as Yennefer tortured him as she pleased,
"Emrys," Jaskier whispered one last time, hoping, praying, that the Dragon Lord could hear him.

“Put that down,” he says sharply, “and back away.”
“What, this old thing?” Skulduggery holds the gun up, waving it around. “Please. This couldn’t hurt a fly. Unless you had very good aim, I suppose…”
“Down,” the man repeats sharply, hair rising up to float around his head, eyes a bright-red hue.
Valkyrie freezes. They don’t know anything about this man or his abilities.
Skulduggery only sighs, flipping the revolver around his fingers so that he’s grasping the barrel and holding the grip out to the teacher. “If you insist.”
The man snatches it away and flicks the safety on. “Students, inside. You two, come with me—we need to ask you a few questions. No funny business.”
“Well, now," Skulduggery murmurs, starting after him, "I can hardly help being funny."
And Valkyrie, despite their current situation, has to smile.
Darquesse shunts Valkyrie and Skulduggery into an alternate dimension where superheroes run around and fight evil—kind of like them, only with quirks and morals and stuff. Now, if only they had a way to get back... -

Summary
The last thing Peter sees is Tony's horrified, heartbroken expression leaning over him. The guilt in his eyes is almost worse than the burning pain that's taking Peter apart piece by piece. The world starts to go dark.
There's a flash of gold and green. For one moment, he finds himself standing amongst the Guardians and others. And then darkness again. It feels like blinking; an extended period of nothingness that ends as abruptly as it begins. One moment there’s nothing, the next there’s light.
“Easy,” a woman says. Her words are gentle, and carry a slight accent that he can’t place. "I'm called Wonder Woman. What's your name?"

[BEING REWRITTEN AS 'OH FUCK TIME IS FLYING' BECAUSE WHAT WAS I ON THIS FIRST TIME AROUND????]
"Maybe," Peter thought, "I can make a life here."
Hence the tears and the guilt and the grief, because was Peter allowed to move on? Was he allowed to… to leave it all behind? Leave all the bad things in the past?
Peter was "The Friendly Neighborhood Spider-Man!" after all, and wasn’t he letting Queens - his people - down if he didn’t fight tooth and nail to get back to them?
orPeter's tired. He's so tired, and he doesn't know what to do, but maybe things will get better.
