Set in 2022, the story follows Yoo Jaeyi, a successful marketing executive whose life changes when she hears a hauntingly beautiful song during lunch at her company cafeteria. The melody feels strangely familiar, leading her to discover Woo Seulgi, a little-known singer from 1974. Drawn by curiosity and emotion, Jaeyi travels to Seulgi's hometown in search of answers. As the past and present intertwine, Jaeyi faces the unthinkable: Can love cross the boundaries of time-and what will it cost her? A tale of longing, fate, and a love that endures beyond eras. *** Inspired by "사랑 그 쓸쓸함에 대하여 (About Love and Its Loneliness)" by Yang Hee Eun.

If someone had told Seulgi three months ago that she'd end up sharing a house with her mother's new fiancé and his daughter, she would've laughed. Or screamed. Or both. Now? Well-she's still screaming. But more internally. Mostly. "I swear to God, if you touch my skincare again, Jaeyi-" "Relax! I was just borrowing your toner. And serum. And... maybe the snail essence. Your pores look rich, I'm trying to invest." Seulgi clenched her jaw, gripping the bathroom doorframe like it personally betrayed her. "Your investment plan is going to end in hospital bills." Living under the same roof as Jaeyi was like signing up for emotional whiplash. One moment she was laughing at Jaeyi doing a ridiculous dance in the kitchen with a burnt pancake on her head; the next, she was staring too long when Jaeyi came home in a sundress that shouldn't be legal. It wasn't fair. It wasn't fair. Because Jaeyi wasn't just annoying. Or pretty. Or funny in a way that made Seulgi want to punch a pillow. Jaeyi was her. The kind of chaos Seulgi never asked for but somehow couldn't stop orbiting around. "You're staring again," Jaeyi teased one evening, perched on the kitchen counter, eating grapes like a Greek goddess with no regard for personal space. "No, I'm regretting my life choices," Seulgi deadpanned, turning away, ears turning traitorously red. Jaeyi tilted her head. "Sure you are. Just like how you 'regretted' sitting next to me during movie night. Or how you 'regretted' holding my hand during that thunderstorm." "That was for safety," Seulgi snapped, grabbing a water bottle just to have something to hold that wasn't Jaeyi's smug face. "Oh? So if another thunderstorm happens, you'll hold someone else's hand?" Silence.

Prologue In a world still spinning from the aftermath of a celestial anomaly-the Arcane Comet-some teenagers began to change. Not all, just a few. Chosen by fate or cursed by chance, they awoke to find themselves holding pieces of the impossible. Powers. Secrets. A ticking clock inside their skin. Yoo Jaeyi was one of them. A sharp-tongued university student with a penchant for trouble and a gift no one was supposed to have-she could bend others to her will, if only for a short while. A flicker of control. A taste of power. And like anyone armed with something dangerous, she tried to use it to her advantage. Cheat sheets. Party invites. A shortcut through life. But freedom has a price. And someone was watching. Woo Seulgi saw through her. A ghost in plain sight, Seulgi walked the world invisible to everyone-everyone except Jaeyi. Their encounter wasn't a coincidence. It was the beginning. Together, they were dragged into the underbelly of the extraordinary: Chaehwa University-a hidden institution posing as an elite school, masking its true purpose. It trained the gifted. Protected them. Controlled them. And sometimes, used them. This story is not about heroes. It is about the ones who didn't ask for this. It is about Yoo Jaeyi and Woo Seulgi-two girls trying to outrun fate, trying to protect others like them, and trying, just maybe, to save each other. Welcome to Arcane.

Seulgi is used to staying quiet, keeping her head down, and avoiding trouble. She doesn't want attention-not from her classmates, not from her past, and definitely not from the world she's been trying to forget. But on the first day of school, things start to shift. Whispers follow her. Eyes linger. And just when she thought she could stay invisible, a familiar face shows up-someone who shouldn't be connected to her life at all. Yoo Jaeyi is calm, confident, and hiding her own secrets. Their worlds were never meant to meet... but something is pulling them together. Now, Seulgi is stuck between who she was, and who she might become-and the more she tries to move forward, the more the past refuses to let her go. As strange things begin to happen around her, Seulgi starts to wonder: Can you really undo the past? Or does it always find a way back? Staring Woo Seulgi and Yoo Jaeyi from Friendly Rivalry.

Jaeyi doesn't do emotions. She leads with silence, works without rest, and keeps everyone at a distance. She's the CEO, disciplined, unshakable, and entirely alone. Then Seulgi walks in, young, curious, and unexpectedly bold, assigned as an intern under her wing. What begins as cold professionalism slowly shifts. A glance held too long. A silence that lingers. And beneath it all, something sharp. Something neither of them dares to name. This isn't love. Not yet. But it's a slow-burning pull, dangerously quiet and impossible to ignore. And once the line is crossed... there's no going back.

What happens when the love you thought was pretend turns out to be the most real thing you've ever known? After the sapphic K-drama Friendly Rivalry skyrockets Lee Hyeri and Chung Subin to fame, the two leads become overnight icons-of chemistry, controversy, and everything unsaid. But behind the scenes, their closeness dissolves into silence, leaving fans wondering what really happened when the cameras stopped rolling. A year later, rumors erupt. Dispatch thinks Hyeri's back with her cheating ex. Subin is spotted in Florida with a mysterious companion. A fan-fueled conspiracy brews... and they're both caught in the storm. But when Hyeri makes a desperate call that leads to a drunken reunion, a glittery Orlando chapel, and a very real marriage certificate, the two women are forced to confront what they've been running from: the truth of who they are-and who they are to each other. As public pressure mounts, secrets resurface, and careers hang in the balance, Raincheck follows two women navigating love, identity, and the cost of staying silent in a world that only pretends to be watching fiction. This isn't just a story about falling in love. It's about choosing it-loudly. Messily. Irrevocably. And maybe, just maybe... asking for no more rainchecks. DISCLAIMER: This story is sprinkled with a dash of reality, a whole lot of "what if," and zero claims to actual truth. It's fan fiction, folks, aka imagination in overdrive. Any resemblance to real events or people is purely because our brains can't help but blur the lines sometimes. Read with your heart, not a fact-checker.

In the midst of unwritten rules and unspoken emotions How do you fight for a love that's forbidden? Subin knows she shouldn't fall, but how do you unlove someone who keeps pulling you closer-only to push you away? Bound by rules, secrets, and a tangled web of emotions, she finds herself caught between what's right and what feels real. But when betrayal cuts deep and lines are crossed, can they still find a way back to each other-or are they destined to keep breaking each other apart? _ "Class dismissed," she said curtly, already organizing her things. I was just about to pack my stuff when I heard her voice again. "Chung Subin." I froze mid-motion, my hand hovering over my bag. Why is she calling me now? The entire class went quiet, their eyes bouncing between me and Ms. Lee. "Yes, ma'am?" I answered, standing up hesitantly. "Follow me," she said, her tone leaving no room for argument. She didn't even look at me as she slung her bag over her shoulder. "And carry this," she added, motioning to a stack of papers and a book she had left on her desk. I glanced at Woo-ri, who was giving me the most bewildered look. "Go," she mouthed silently, clearly curious but also worried. I walked over to Ms. Lee's desk, quickly grabbing her things. Turning to Woo-ri, I gave her a small wave. "I'll catch up with you later, Woo-ri," I said softly. "Go ahead without me." "You sure? Don't let her eat you alive!" she whispered dramatically, but I waved her off with a nervous smile. _ A professor and her student, drawn to each other in ways neither of them can explain. The boundaries are clear, but their emotions refuse to be ignored.
