Summary
Fuck, Sangwon looks so small. He always looks small, but Leo's oversized shirt is so loose on him he's practically drowning in it. His eyes are still widened just so, his mouth slightly parted in that airy, curious way it did when he really was eighteen.
Leo wants to fuck him.
Sangwon looks just like he did when he was on the edge of adolescence, and Leo wants to fuck him.
△▼△
Sangwon dyes his hair, and Leo is reminded a little too much of the boy he first fell for.

Summary
Sangwon never imagined that South Korea would be eliminated from the World Cup after losing 3–2 to Australia.
Much less that he'd end up fucking the Australian striker who scored the winning goal against them.
Or
For years, Leo had watched Sangwon wear South Korea's uniform, never expecting that his longtime rival would end up looking better without it.

Summary
It started as stress relief—a way to ground themselves during the chaos of Boys Planet. No feelings, no expectations, nothing to talk about. That was the agreement.
But Sangwon has been in love with Leo for years, and pretending it means nothing is starting to feel impossible. Especially when Leo looks at him like that. Especially when Leo stays the night and doesn't touch him at all.
Or: Sangwon and Leo have been sleeping together since the program. Sangwon is fine with it. Really. He's fine. (He's not fine.)

Summary
"Are you of age, Sanghyeonie?" Sangwon teases and the words clearly catch Sanghyeon off guard, the other hybrid's ears drooping slightly.
"Of course I am, I'm not that young! I'm eighteen," The puppy huffs, whining slightly at Sangwon. God is he cute, Sangwon wants to lean over and pinch his cheeks, he has that boyish charm to him that he really likes. Eighteen wasn't too bad, but now he's a little curious to know how old Leo is, maybe he could ask Sanghyeon to hook him up with his brother.

Summary
"Unnie," Sangwon whines. "Fuck, unnie."
"Sangwon," Leo warns, finally breaking eye contact to lean her head against the cool wood of the door.
"What, unnie?" Sangwon asks innocently. "Do you like watching me?"
"Do you like me watching you?" Leo asks gruffly. She's so close to snapping and touching herself, but something akin to shyness stops her.
OR
Five times Leo catches Sangwon having fun, and one time they both finally snap.

Summary
For a moment, Leo wonders if he somehow walked into the wrong dorm room. He whips his head around for some sort of sign, something unfamiliar, and instead finds a room he hasn’t seen in almost four years.
The posters on the wall, the bunk beds, and the piles of clothes from seven teenage boys scattered around the space—Leo’s mind struggles to catch up and make sense of the situation. It doesn’t click until he looks back down at Sangwon hiding in his duvet, the flush on his cheeks perfectly framed by his dark brown hair.
The Sangwon that Leo saw a few hours ago was blonde.
Or, a 2026 Leo walks into the bedroom of 2022 Sangwon.

Summary
"Nice to meet you, Leo-ssi. I'm a hugger, is that okay?" Sangwon asks, already stepping into his vicinity before Leo can react.
"Just call him 'hyung', Sangwonie. He doesn't mind. Right, Leo-hyung?" Xinlong says as Leo wraps his arms around Sangwon's waist, and Sangwon's around his neck. Leo wants to lick him all over until he's screaming.
Leo keeps a lingering palm on Sangwon's back when they pull away. He licks his lips, "Of course I don't. A friend of Geonwoo's is a friend of mine."

Summary
He stuffs the dildo in as deep as it can go, the tip of it crowding against his cervix almost painfully, before he sits up slightly, bringing the end of the rose toy to his clit, and opens his eyes to look at the mirror again, eager to see just what face he’ll make when he squirts all over the floor.
Just as Sangwon nearly reaches the sweet edge of release, his body spasming as he shoves the rose toy against his clit, he catches movement out of the corner of his eyes. He freezes when he locks eyes with a wide-eyed and gaping Leo, his work bag slipping from his shoulder and banging loudly against the floor as he stares at Sangwon in shock, his eyes darting from Sangwon’s clouded eyes to his soaking cunt, before looking back up again, swallowing audibly.
“Leo…?” Sangwon squeaks out, his voice sounding disconnected from his own body, his heartbeat too loud in his ears, panic rising when he realizes his legs are still splayed wide open, a clear view of the dildo stuffed in his pussy on display.
Or:
Sangwon really needs to learn how to lock his door.

Summary
Leo's hand found her knee, thumb tracing lazy circles there; innocent enough, but the touch sent a warm thrill up her thigh. "You're full of energy today," he noted, his tone casual, but she caught the glint in his eyes. He knew her too well, sensed the mischief simmering beneath her sweet demeanor, yet he didn't pull back. If anything, he encouraged it with a gentle squeeze.
She giggled softly, batting her long lashes as she traced a fingertip along his arm, up to the sleeve of his hoodie. "Just happy to be here with you." Her hand wandered to his thigh next, palm pressing lightly under the pretense of brushing off a crumb. The muscle tensed under her touch, and she felt the subtle shift in his breathing.
Tension coiled between them, slow and delicious, like a secret unfolding in the sunlight.
