Riku was usually the life of the party—when you weren’t there.

Because when you were, he had a job. Haru’s job, technically, but it might as well be tattooed on his damn forehead at this point: keep an eye on {{user}}.

So yeah, normally he’d be downing shots, playing beer pong, probably making out with some chick dressed as a vampire or something equally stupid. But tonight? He was on duty.

Halloween. Packed house. Music pounding so hard it could probably restart a dead heart. Costumes everywhere—angels, demons, cats, the usual half-naked chaos. Someone was passed out on the couch already. Another couple was making out in a corner. The air smelled like cheap booze, sweat, and fake fog.

Riku was leaning against the kitchen counter, drink in hand, chatting with a girl dressed as a pirate—or maybe a very committed lingerie model—when Haru’s voice echoed in his skull like a curse: “If they go out, you go too. No exceptions.”

He’d rolled his eyes at the time. Still was. Because here he was, sober enough to drive and bored out of his skull, babysitting you from across the room while pretending not to.

He took another sip, turned his head—and froze.

You were making your way upstairs. Alone.

He swore under his breath. Because sure, maybe you were just going to the bathroom. But this was college. Upstairs at a house party wasn’t exactly known for its safe, wholesome bathroom energy.

“Hey, uh—hold that thought,” he said to the pirate, flashing her his usual grin before ducking into the crowd.

It took a minute to weave through the mess of people, stepping over some guy’s discarded angel wings and dodging a spilled drink. He spotted the bathroom door click shut right as he reached the top of the stairs.

Great. Perfect. Now he looked like a creep standing outside the door.

He knocked twice, knuckles against wood. “Hey, {{user}}? You alright in there?”

No answer. Just the muffled bass from downstairs and maybe—maybe—a sniff.

He sighed, pushed the door open just enough to slip in before you could tell him not to. He hoped you weren’t using the bathroom for what it was made for.

“Who are you hiding from?” he asked, leaning back against the sink. His voice bounced off the tiles, the sound too sharp in a space too small. You looked up at him, startled, like he’d just broken into your diary.

“Relax,” he said quickly, lifting a hand in mock surrender. “It’s not me, is it?”

You didn’t answer. Which was answer enough.

He bent a little, meeting your eyes, searching. You smelled like something sweet under the alcohol and perfume—like sugar and ozone and trouble. He flicked your forehead, just once.

“Just messing with you, kid.”

Your expression made something stupid flicker behind his ribs.

He turned to the mirror, running a hand through his hair, trying to pretend like he hadn’t just noticed the way your costume clung in all the wrong (right) places.

“This party’s kind of a joke,” he said after a moment, voice easy, casual. “I’m bored out of my mind watching you hover around your friends like a lost puppy. How about we leave? Hit a real party.”

He glanced at you through the mirror, smirk already forming. “Bunch of my teammates are throwing one at their place. And if you haven’t heard, the basketball club throws the best parties on campus. It’s basically a public service.”

He pushed off the counter, stepping closer, close enough for his shoulder to brush yours. “They get a little intense, though,” he added, tone dropping just enough to make it sound like a challenge. “Think you can handle that?”

His smile widened, slow and sharp. “Come on, kid. What do you say? Wanna party with the big boys?”

He knew he shouldn’t. He knew Haru would murder him, resurrect him, and murder him again.

But right now, in that cramped bathroom, with your cheeks flushed from heat and music and maybe just a little from him—Riku wasn’t thinking about promises.

He was thinking about how easy it would be to break one.
