The summer before fourth grade was hot and endless, stretching out like a golden eternity under a sky so blue it could have been painted by angels. In the small town of Lima, Ohio, where everyone knew everyone else's business and gossip spread faster than wildfire, two children formed a friendship that felt as though it had existed long before they were even born.

Rachel Berry and Sam Evans were inseparable that summer, running barefoot across sun-warmed pavement, chasing fireflies in the dusk, and building forts in the woods behind their houses. They were both dreamers—Rachel, with her Broadway aspirations and larger-than-life confidence, and Sam, with his comic books and boundless imagination.

It was fate, really. The kind of friendship that happens once in a lifetime, if you're lucky.

Rachel had always been a lonely child. The only daughter of two doting fathers, she had been raised on a steady diet of show tunes, organic snacks, and carefully planned playdates with children who were more like business contacts than real friends. Other kids thought she was strange, always talking about Barbra Streisand, using words far too big for her age, and singing show tunes during recess instead of playing tag. She never fit in at school, and she knew it.

But Sam didn't seem to care.

He moved in next door the summer before third grade, and from the moment Rachel saw him—barefoot, tugging a battered Captain America backpack over his shoulder—she decided they were going to be best friends. Sam was different. He didn't laugh when she talked about Broadway or look at her like she was an alien when she mentioned Sondheim. Instead, he nodded thoughtfully, like he was actually considering what she had to say.

"Who's your favorite superhero?" he had asked her that very first day, sitting cross-legged in her backyard, squinting at her in the summer sun.

"Barbra Streisand," Rachel answered confidently.

Sam blinked. "She's not a superhero."

"Yes, she is," Rachel insisted. "She can do anything."

Sam had thought about that for a moment, then shrugged. "Okay. My favorite is Aquaman, but he's kinda lame. Superman's cooler."

"Superman is unoriginal," Rachel argued.

Sam grinned. "Guess that means we can't be best friends, then."

Rachel narrowed her eyes. "Fine. But I get to be Wonder Woman when we play superheroes."

And that was that. A friendship was forged between two kids who didn't quite fit in anywhere else.

They spent entire afternoons pretending to be superheroes, running through the woods with makeshift capes made of old bedsheets. Sam was always the leader, shouting out imaginary missions, while Rachel took charge of the storyline, narrating their grand adventures as if she were directing a Broadway play.

One day, they found a hidden clearing deep in the woods behind their houses, a magical little spot where the sun streamed through the leaves just right, making the whole world look golden. They decided it would be their secret hideout.

"We need a name," Sam declared, brushing dirt off his shorts.

Rachel tapped her chin, deep in thought. "The Fortress of Stardom!"

Sam made a face. "That sounds lame."

"Excuse me,Captain America Knockoff, but I think it sounds perfectly theatrical."

He rolled his eyes. "What aboutThe Star Fortress?"

Rachel considered this. "I suppose that will do."

And so it was. Every day after school, they would sneak off to their hideout, carving their initials into the bark of a tree and pretending they were the rulers of a secret kingdom. They shared their dreams there—Rachel's plans to be a Broadway star, Sam's wish to be a famous comic book artist. They promised they'd always be best friends, no matter what.

But promises made in childhood rarely last forever.

Middle school changed everything. Sam joined the football team, and Rachel—while still as loud and dramatic as ever—became even more obsessed with her dreams of stardom. She spent more time at vocal lessons, entering talent shows, and practicing monologues. Meanwhile, Sam's world became all about sports, video games, and hanging out with the guys.

By eighth grade, they barely spoke.

Rachel saw him in the hallways, laughing with the other boys, blending in effortlessly. He wasn't the same Sam who had once played superheroes with her, who had promised they'd always be friends.

And then, in high school, things only got worse.

Sam became one of the popular kids, the star quarterback with an easy smile and a natural charm that made everyone want to be around him. Rachel, meanwhile, had solidified her role as the school's resident theater nerd, the girl who never shut up about Broadway and was an easy target for bullies.

They weren't enemies, exactly, but they weren't friends anymore, either.

Sometimes, Rachel would catch him looking at her across the cafeteria, a flicker of something unreadable in his expression. But he never said anything, and neither did she.

The past was the past.

Or at least, that's what she told herself.

It was a Friday afternoon when Rachel's phone buzzed with a text from Noah Puckerman.

Noah was the one person Rachel still considered a friend—sort of. Their families had known each other forever, and while Noah was the bad boy of the school, always skipping class and getting into trouble, he had a soft spot for her. He never let anyone mess with her and checked in on her more than she liked to admit.

-Hey, Berry. Party at my place tonight. You should come.

Rachel scoffed, rolling her eyes.

-You invite me to every party, and you know I never go.

-Yeah, but you should come to this one.

-Why?

-Because I said so. Stop being lame.

Rachel hesitated. She didn't do parties. She didn't drink, didn't dance, and definitely didn't fit in with the kind of crowd that would be there.

But a small, rebellious part of her—the part that was tired of feeling like she was missing out—considered it.

-Fine. I'll think about it.

-Good. Wear something hot.

Rachel rolled her eyes again but couldn't help the small smile that tugged at her lips.

She had no idea that one impulsive decision would change her life forever.
