Oh Sion is not the type of guy who talks to someone like Maeda Riku.
He doesn't seem like it, anyway, not when he's so handsome and confident and popular, and Riku's backpack is covered in video game pins and badges packed so densely together you can barely see the huge Genshin Impact logo printed on the front. And it's not like they really have any reason to talk, given that Sion is a third year, and Riku's just a second year. A second year with oversized glasses and a too-tight tie tucked into the sweater vest that is of course not mandatory at their university, but that he likes to wear anyway because he enjoys looking smart.
Oh Sion is far too cool to give someone like Maeda Riku the time of day, and yet…
Meet me on the roof.
The message comes in the form of Sion's usual scrawl, half-smudged on the folded piece of paper he presses into Riku's palm as they pass in the hall. Riku's heart leaps in his chest, despite the fact that this is far from the first time Sion has asked him to meet him alone. He scrunches the note up, stuffing it into his pocket as he makes his way to his next class.
When Riku had first started university, he had done so with a plan. He'd worked hard to get into a good school, and nothing was going to get in his way. He was going to keep his head down, avoid parties and drama and girls, and come out with a first-class degree in computer science. He wasn't going to get distracted by any baggy-jeans-wearing, muscled boys a year older than him, especially not one with a tongue piercing and freshly-dyed red hair.
But things don't always quite go to plan for Maeda Riku.
His late morning class is a complete write-off, as distracted as he is by the thought of Sion waiting for him up on the roof. He won't be there yet - he knows Riku's schedule as well as his own, even if he vehemently denies that whenever Riku asks.
He can't help but watch the clock as the minutes slowly tick past, his notes forgotten as his lecturer drones on and on about things he should probably be listening to. He can't help it. Sion just has this way of getting in his head and keeping him from focusing on anything other than the thought of kissing him.
The first time that happened, they'd been in too close proximity for Riku to get away with denying it. Unfortunately, Riku's plan to earn money without taking time away from studying - by tutoring other students in his subject - had proved even more distracting than a normal job, thanks to the beautiful boy sat opposite him.
"It's kind of hard to focus when you look like you want to kiss me," Sion had said, looking up from where he'd been studying the notes Riku had given him. Riku had just gaped at him, eyes wide as he tried to think of some way to deny it.
"I-I'm not-"
"Then why do you keep looking at my lips?" Sion had pressed, leaning forward on his elbow, his chin resting on his palm. The way he'd raised his eyebrow had made Riku's mouth run dry and mind go blank.
"I-I was just curious, about… about your tongue piercing," Riku had dumbly admitted. He'd known it was a mistake from the way a slow grin had spread over Sion's lips.
"Oh yeah?" Sion had asked, eyes flicking down pointedly to Riku's own lips, chewed pink with anxiety. "Wanna know how it feels?"
Riku, now, shakes his head at the memory. The following events are not ones he can afford to remember in class, but their very first tutoring session had ended with Riku having had his first kiss and lost half his virginity. He swallows thickly, adjusting his tie before taking a sip of water from his bottle. Another glance at the clock tells him it's 11:52. Just eight minutes and he can escape up to the roof with his- with Sion.
They've never spoken about their… arrangement. It's been three months since they first started sneaking around, and the topic of what they're doing has never been broached by either of them. Deep down, Riku knows this is all just a bit of fun for Sion - Riku isn't the first person he's messed around with, and he won't be the last. Whether Sion understands what all of this means to Riku is another story, because Riku doesn't do this. He's never even dated before, and until Sion, hadn't even considered it - mainly because he's never had an interest in girls. No shit, he realised, about two weeks into their ambiguous set up. Because I'm gay.
Riku hasn't told any of his friends, either - not even Yushi, who will kill him for keeping this a secret if he ever finds out. Luckily, Riku's sure that he won't, convinced that this thing with Sion will simply fizzle out before that happens. Even though the thought of that happening makes his stomach turn with dread and tears prick at the corners of his eyes.
12:00. The lecturer dismisses them, and Riku scrambles to shove his things in his bag, uncharacteristically uncaring of how they land. His seatmate looks at him curiously but ultimately deigns not to comment, and less than thirty seconds later, Riku is speed walking along the hall to the stairwell.
He gets a few bumps on the shoulder as he passes against the flow of students heading to the cafeteria, ones that are too hard to be an accident. He doesn't look around, loath to provide anyone with a reason to stop and give him an earful. He adjusts his backpack on his shoulders, buttons and badges clinking, and continues upstairs.
The door to the roof is heavy when he pushes it open, and it takes him leaning his entire weight against it before it moves with a loud scrape against the concrete. He slips out as soon as there's enough room, looking around to take in his surroundings.
Sion is already there, sitting with his back to Riku on a ledge a few metres back from the edge of the roof. He has a grey, zip-up hoodie on over a tight, black tank top and baggy jeans, the hoodie half slipping from his shoulders to reveal his toned arms. Riku gulps, looking down at his own clothes, and wondering - not for the first time - what Sion's doing messing around with someone like him.
He sighs, the breeze mussing his hair as he wraps his arms around himself, making his way across the roof.
"Hyung," he says quietly when he's close enough to be heard. Sion turns, his face breaking into a grin that Riku can't help but tentatively return.
"You made it," Sion says, looking up at him and patting the concrete at his side. "Sit with me?"
Riku crouches down, tucking his legs under him as he sits. Sion shuffles closer to him, closing the distance between them so their shoulders touch. And then: silence.
Riku side eyes him, confused. They usually get down to business pretty much straight away when they meet, especially if they're sneaking off for a quick tryst between classes and don't have much time. Sion doesn't seem to be one for patience when it comes to their meetings, but Riku doesn't mind. He wants Sion too much to care how little time they have.
But, now… nothing. Sion stares at the view, silent but for his breaths. Riku glances at him every so often, wondering if he should say anything. If he can say anything. Sion's shoulder is warm against his, and their hands rest side by side on the concrete. Riku's little finger twitches with the urge to reach out and touch.
"Hyung," Riku murmurs. "Are you okay?"
"Yeah, I'm okay," Sion says, but his voice sounds weird, tight. Riku's eyebrows pinch.
"Why did you ask me up here?" Riku asks, voice so quiet he thinks Sion may not have heard him, especially when he's met with silence. When he turns to look at Sion properly, he frowns. Sion's looking down at the ground, his lip caught between his teeth. His foot taps restlessly against the floor. He looks- he looks nervous.
"I wanted to talk about something," Sion whispers. "I've wanted to for a while."
Riku's stomach fills with dread, tensing where he sits. This is it, isn't it? This is where it ends. Sion's probably bored of him, or he's done something to put him off - either way, Riku's certain Sion is about to end it.
"I-It's okay," Riku says, trying to sound unbothered even as his voice cracks. "I get it, we can- we can stop this, if you want."
Sion freezes, his foot unmoving as he turns to look at Riku. Riku keeps his gaze locked straight ahead, on the big bell tower in the centre of the campus - though he can feel Sion's eyes on him, hot against his cheek.
"End it?" Sion asks. "Is that what you want?"
"I-I don't know," Riku lies. He does know, he knows exactly what he wants - and it is not to end it. He gulps, tongue-tied. He wants to tell Sion, admit how he feels before it's too late, but- it already is, isn't it?
Sion twists around on the ledge, angling his body towards Riku's. He gently touches his elbow, trying to get him to turn. "Riku-yah," he says softly, "look at me."
Riku obeys, turning his head and looking up at Sion through his big glasses as he nibbles on his lower lip. Sion's hand trails down from his elbow to lace their fingers together, and Riku's breath hitches.
"I was going to say I'd like to make it official," Sion says, smiling softly. His red hair blows messily in the wind, the noon sunlight making it glow. Riku's mouth drops open in surprise, eyebrows raising.
Sion's eyes dart to the side. He's still nervous. "What- what, um, do you think about that?" he asks, his normal, confident bravado nowhere to be seen.
Riku squeezes his hand, his heart pounding. He feels breathless, excitement building in his chest as he takes in Sion's words. "Hyung…"
"It's okay if you don't want to," Sion says hurriedly, "but- just- I don't want to end it. We can keep it casual, if you want- I can be casual-"
"Hyung," Riku interrupts. "I don't want casual."
"You…"
"I've never wanted casual," he continues. "Not with you."
Sion's lips pull into a lopsided smile before he bites it back, gaze still off to the side. His cheeks are pink, Riku notes. He doesn't think he's ever looked so beautiful.
"So- so, what does that mean?" Sion asks. Riku shrugs, lip still caught between his teeth. Sion looks back at him finally, his free hand coming up to clutch in the material of Riku's sweater vest. "Does that mean we can be- like- boyfriends?"
"Yes," Riku blurts. "I mean, um, yes, if you want."
Sion grins, releasing his hold on Riku's vest to run his hand through his hair. "Oh my god," he breathes, "you have no idea how nervous I've been about this."
"I didn't know you felt this way," Riku says, nibbling on his fingernail. "I thought you… I didn't know you wanted me like that."
"I do," Sion admits. "I want you in any way I can have you, boku no hime."
Riku flushes from the tips of his ears down to his toes at Sion's use of Japanese. It's not the first time he's called him his princess, but it's different hearing it now.
Riku averts his gaze, looking down at Sion's chest - though the view that greets him grants him absolutely zero respite. He huffs out a laugh. "Then have me," he whispers, embarrassed.
He feels Sion's hand on his jaw, cupping it gently, and Riku's eyes slip shut as he allows Sion to take control. He presses their lips together softly, so softly it makes Riku's heart clench. He likes Sion so much it hurts.
The kiss starts far more chaste than their kisses usually do, but it doesn't stay that way for long. Sion gently swipes his tongue along Riku's bottom lip, and Riku responds by flicking his own tongue against it and letting his mouth drop open. Sion's grip on his jaw tightens as he straightens his back, using his superior height to lean over Riku slightly, his other hand snaking around his waist. Riku moans softly, hands coming up to hold Sion's arms like a lifeline.
The kiss deepens further when Sion prods his tongue between Riku's teeth, and Riku gladly wraps his lips around it to suck, Sion's piercing cold against them. Sion groans, fingers flexing against Riku's waist before he grips his sweater vest in his fist, tugging it free from where it's tucked in Riku's slacks.
Riku makes a small noise of surprise but he lets Sion break the kiss to pull his vest over his head regardless, his eyes unfocused until they slip shut again with the rejoining of their swollen lips. They kiss languidly for a few more minutes, Sion's hand roaming over Riku's back, sneaking up under his shirt to scratch at his skin. Riku just clutches at him - at his boyfriend - kissed breathless and thoughtless and shameless as Sion works him up.
It's when Sion's lips find their way to his neck that Riku lets out a whine, running his fingers through Sion's hair. Sion chuckles against his neck, loosening his tie with one hand and undoing the top button of his shirt for better access. He holds Riku against him, hoodie slipping from both shoulders as he sucks and bites his way down to Riku's collar.
"Sion-hyung," Riku moans. "I'm so-"
"I know, baby," Sion breathes against his neck. "I think we have time to-"
There's a sudden, loud chime of one bell. Time's up.
"Noooo," Riku whines, "hyung, we can-"
"No way," Sion says. He sits back, running his hand through his hair and adjusting his hoodie. "I'm not going to be the reason you miss class for the first time. Absolutely not."
"God," Riku curses, "okay, shit, fine."
"I'll see you after your class," Sion promises, his own classes finished for the day.
"If you're lucky," Riku grumbles. He scrambles up from the ledge, attempting to straighten out his shirt and tie. His sweater vest lays forgotten on the ledge as Sion stands too, swiping Riku's hair from his eyes. He kisses him one last time, deep and passionate, until Riku is pushing at him with a laugh.
"I'm already late," he complains, grabbing his backpack and all but sprinting to the stairwell. He turns just as he reaches the door, turning back to watch the way Sion waves. He wants nothing more than to run back to him and spend the rest of the afternoon tucked into his side, but Sion's right. No missing class, not even for the hottest boy he's ever met.
He gets to his lecture just in time, his tutor still setting up at the front. However, he isn't early enough not to earn a strange look from his best friend, Yushi already seated at their usual table.
"Hey," Riku says, pulling out his laptop and doing his best to refocus on the task at hand. After a few moments, however, he realises that Yushi is still looking at him. "What?"
"Where were you at lunch?" Yushi asks. He looks very curious… suspicious, even, and Riku gulps, suddenly hyperaware of his dishevelled appearance.
"Library," he lies. "I lost track of time, so had to run over here."
"Right," Yushi says, seeming to accept the simple explanation until he speaks again a few moments later. "Except, I was in the library at lunch, and I didn't see you there."
"Oh." Riku shifts uncomfortably in his seat. "We must have just missed each other."
"Right," Yushi says again. A few more moments pass, maybe even thirty seconds. Riku thinks he might be in the clear, but… "Except," Yushi continues, "you have a huge hickey on your neck."
Riku gasps, slapping his hand over where he knows Sion had sucked. But he didn't think it had been hard enough to bruise! Sion has never given him a hickey before, but even through his mortification, Riku has to suppress a smile at the thought.
"What the fuck was that!" Yushi hisses. "You smiled! Riku! What is going on!"
"I- uh, I-"
Riku's saved by their tutor, who calls for everyone's attention at the front of the room, signalling the official start of class. It's a lecture, not a collaborative workshop or seminar, which means Yushi doesn't get another chance to question Riku until they're packing their things up an hour later.
"You need to tell me everything," Yushi demands. "I can't believe you were late to class because you snuck off to god knows where to make out with god knows who-"
"I'll- I'll tell you," Riku promises. "I will, I swear, just-"
He cuts himself off when he exits the room, Yushi in tow. Sion is there, leaning against the opposite wall with his arms crossed and looking so gorgeous Riku worries for a moment that he may have hallucinated their entire conversation on the roof. It isn't until Sion looks at him, a wide smile taking over his entire face, that he knows he didn't. Even as countless people pass him, greeting them as they go, Sion's eyes remain on Riku.
Suddenly, Riku remembers the bruise on his neck, and he points to it, levelling Sion with a look that at least has the older man looking a little bashful. He pushes himself off the wall, stepping forward, and Riku becomes painfully aware of Yushi's presence beside him.
"Come on, Riku, let's go," Yushi urges, seemingly still clueless about the fact that the topic of the conversation he's so eager to have is standing just a few metres away from them.
Riku nods absentmindedly, beginning to move in the direction Yushi is yanking his arm in. He looks at Sion apologetically, but Sion just grins. He crosses the hallway, pushing past a group of students, and…
"Excuse me, I think you dropped this," Sion calls out, wrapping his fingers around Riku's forearm. Riku looks at him like he's grown three heads until he feels Sion press a small piece of paper into his hand.
"Oh, t-thank you," Riku says, cheeks pink as he finally lets Yushi pull him away. Sion winks, smiling as he watches Riku stumble over his feet.
"What the fuck was that?" Yushi asks, looking back at Sion and then to Riku and back again, the realisation dawning on his face. "Don't tell me… with him…!"
"Hm?" Riku hums, not really listening as he unfolds the piece of paper. He bites back a smile when he reads it, that same messy scrawl smudged in the creases of the paper, a torn page from Sion's notebook.
Riku, come to my room.
