Cole Hartley rinsed the blender cup in the kitchen sink and watched the last of the protein shake swirl down the drain, pale and chalky against the stainless steel. The apartment had settled into that particular late-evening quiet he’d come to know over two years of sharing it: the refrigerator humming, the campus Wi-Fi router blinking steady green on the counter, the faint chlorine smell that never quite washed out of the air no matter how many times Tristan showered.

He liked the quiet. Wrestling practice had run long, Coach Mercer drilling takedowns until Cole’s thighs burned and his shoulders ached, and now the silence felt earned. He set the blender cup in the drying rack and let his gaze drift across the kitchen. Two protein tubs stood on the counter, chocolate and vanilla, one of them half empty and the other scraped clean. A swim team hoodie hung over the back of a dining chair, and his own wrestling gear bag lay by the door where he’d dropped it an hour ago. The apartment was small and it was messy and it smelled like two athletes who spent more time training than tidying, and Cole wouldn’t have traded it for anything.

He caught his own reflection in the dark window above the sink: six-two, shoulders still carrying the pump from practice, dark hair damp at the temples. He looked tired, but it was the satisfying kind of exhaustion that let him set the day aside once he got home.

Usually he stopped noticing the cedar in his own scent, but tonight he caught it beneath the chlorine. His spice and Tristan’s rain and citrus had worked into the furniture and the walls until Cole could no longer imagine the apartment smelling any other way.

Cole turned away from the window and walked into the living room.

The couch was the one piece of furniture they’d bought together, a dark gray sectional wide enough for two men their size to sprawl without touching. Cole dropped onto his end and stretched his legs out, letting his head fall back against the cushion. The ceiling had a water stain in the corner from the winter before last, when a pipe froze and burst and they’d spent an evening bailing water into a stockpot while Tristan cursed the landlord in increasingly creative terms. Cole smiled at the memory without meaning to.

The bathroom door opened down the hall, and a wedge of steamy light spilled across the floor.

Tristan Bennett walked out with a towel around his neck and his hair still dripping, sandy-blond and dark at the ends where the water weighed it down. He’d pulled on gray sweatpants that sat low on his hips and nothing else. His chest was still flushed pink from the heat of the shower, the defined lines of his shoulders and abs catching the lamplight as he moved. He was humming something Cole didn’t recognize, off-key and unbothered about it.

Cole watched him for maybe three seconds. Then he looked at the ceiling.

“You left your protein on the counter again,” Cole said.

“I left my protein on the counter because I’m still using it.” Tristan’s voice came from the kitchen, easy and unhurried. Cole heard the refrigerator open. “You could try minding your own business.”

“It’s my kitchen too.”

“It’s our kitchen, and I’ll leave my protein wherever I want.” The refrigerator closed. A cupboard opened. “You’re just mad because I used the last of your vanilla.”

Cole lifted his head. “You didn’t.”

Tristan appeared in the kitchen doorway, leaning against the frame with a glass of water in one hand and a grin that was too wide to be innocent. “You should label your stuff if you care so much.”

“There’s a tub with my name on it. In Sharpie.”

“Sharpie washes off.”

Cole let his head fall back against the cushion. “You’re the worst roommate I’ve ever had.”

“I’m the only roommate you’ve ever had.” Tristan crossed the room and dropped onto the opposite end of the couch, close enough that the cushion dipped and Cole’s weight shifted toward him. He smelled like soap and something underneath it that Cole’s brain registered before he could stop it: rain, citrus, a sweetness that lingered at the back of his throat. The sweetness was warmer than it used to be, difficult to ignore with Tristan sitting so close.

Cole kept his eyes on the ceiling. “Doesn’t make me wrong.”

Tristan settled into the corner of the couch, one leg tucked under him, the other stretched out along the cushions. His foot ended up maybe six inches from Cole’s thigh. “How was practice?”

“Long. Mercer’s in a mood.”

“He’s always in a mood.”

“He’s in a worse mood. We’ve got the conference tournament in ten weeks and he’s decided we’re not ready.” Cole rolled his head to the side, just enough to see Tristan’s face. His stepbrother was watching him with an expression that was half sympathy and half something sharper, the way he always looked when the topic turned to competition. “How was the pool?”

Tristan’s grin came back. “Freezing. The heater in the practice pool is acting up again, so the water was colder than usual. My shoulders are going to hate me tomorrow.” He rotated one arm, wincing theatrically. “At least I got to skip the last set. Coach pulled me out to talk about the meet this weekend.”

“The one you’re going to lose?”

“The one I’m going to win. Dramatically. While you watch from the stands and try not to look impressed.”

Cole snorted. “Swimming’s not a real sport.”

“Excuse me?”

“You heard me. You get in a pool and splash around for a while. I have to throw grown men onto a mat.”

Tristan sat up a little straighter, and Cole dragged his attention from Tristan’s stomach back to his face. “Splash around. You think I splash around.”

“I think you get wet and call it conditioning.”

“I’d like to see you do a single two-hundred fly. Just one. I’ll time you.”

“I’d rather not drown.”

“You wouldn’t drown. You’d make it about fifty meters and then your shoulders would give out and you’d have to be rescued by the lifeguard.” Tristan’s grin had turned sharp at the edges, the way it always did when they got going. “It’d be embarrassing. For you. For the wrestling team. For the whole university.”

Cole turned his head fully toward him. “You’re very confident for a guy whose sport doesn’t involve any contact.”

“Swimming’s harder.”

“Wrestling’s harder.”

“You only think that because you’ve never done a real workout.”

“I’ve never done a real workout,” Cole repeated. He let the words hang for a beat. “I spent three hours getting thrown into a mat tonight. What did you do? Count tiles?”

Tristan laughed, a bright sound that filled the living room and settled somewhere in Cole’s chest. “I did five thousand yards before breakfast. You were still asleep.”

“Because I was up late studying.”

“You were up late watching highlight reels of your own matches.”

Cole opened his mouth to argue, then thought better of it. “That was one time.”

“It was three times last week.”

“You’re keeping track?”

“Someone has to.” Tristan took a drink of his water, watching Cole over the rim of the glass. His eyes were blue-green in the lamplight, and Cole found it difficult to believe this was still only a joke when Tristan kept watching him that way. “You’re very predictable, Cole. It’s one of your flaws.”

“I don’t have flaws.”

“You have so many flaws. I keep a list.”

“Show me the list.”

“It’s in my head. Item one: steals my protein powder.”

“You steal mine.”

“Item two: thinks wrestling is harder than swimming.” Tristan held up a third finger. “Item three: leaves his gear bag by the door every single day like the floor is his personal storage unit.”

Cole glanced at the bag by the door. He didn’t move to pick it up. “That’s not a flaw. That’s efficient.”

“That’s lazy.”

“It’s right where I need it tomorrow morning.”

“You could put it in your room.”

“I could.” Cole let a beat pass. “I’m not going to.”

Tristan shook his head, but he was still smiling. He shifted on the couch, settling deeper into the corner, and his foot drifted closer to Cole’s thigh without quite touching it. “You’re impossible.”

“I’m consistent.”

“Same thing.”

Outside, someone laughed on the sidewalk below their window, the sound distant and swallowed by the glass. Cole let his eyes close for a moment and felt the tiredness settle into his bones, heavy and familiar. Between classes, practice, and the weekend meets, he rarely had to wonder what to do with himself. He’d arranged his life that way, and he liked knowing what came next.

When he opened his eyes again, Tristan was watching him with his head tilted against the couch cushion. Cole might have dismissed a quick glance as Tristan checking whether he’d fallen asleep, but the look lasted. Without the familiar grin, Tristan’s expression was difficult to read. The towel had slipped off his shoulders onto the cushion beside him, and his hair was drying in uneven waves across his forehead.

Cole looked at the ceiling again.

“You’re doing it,” Tristan said.

“Doing what?”

“The thing where you look away.”

Cole didn’t move. “I don’t know what you’re talking about.”

“Sure you don’t.” Tristan’s voice was light, almost amused, but there was an edge underneath it that Cole couldn’t quite name. “You do it all the time now. You look at me, and then you look somewhere else. Like you’re afraid I’m going to catch you.”

“I’m not afraid of anything.”

“Then stop looking away.”

Cole turned his head. Tristan held his gaze, the teasing gone from his face, and Cole had the uncomfortable sense that he was being asked a question he couldn’t answer with another joke.

“See?” Tristan said. “That wasn’t so hard.”

Cole held his gaze, counting off the seconds until he could no longer bear to let it continue. “You’ve got water dripping on the couch.”

Tristan blinked and looked down at the damp spot spreading on the cushion beneath his hair. “Shit.” He grabbed the towel and scrubbed at it, giving Cole a chance to breathe without being watched.

Tristan had been part of his life for six years now, ever since their parents met at some fundraising dinner and decided, apparently within weeks, that they wanted to get married. Cole had been sixteen, angry about everything, certain that a stepfather and a stepbrother were going to ruin whatever stability he’d managed to carve out for himself. Tristan had been fifteen, all sharp elbows and sharper comebacks, and they’d spent the first six months circling each other like opponents who hadn’t decided whether to fight.

They never did fight. Instead they’d fallen into something stranger: a competitive friendship that didn’t fit any of the labels people tried to give it. They weren’t brothers. They’d never been brothers. They were two guys who happened to share parents and an address, and then eventually an apartment, and somewhere along the way Cole had started noticing things he shouldn’t.

The change in Tristan’s scent was harder to dismiss than anything Cole could catch himself watching. It followed him through the apartment now, lingering in rooms after Tristan left them. He knew what that meant. Tristan’s Omega biology was responding to something, and Cole’s Alpha biology was responding right back, and neither of them had said a word about it.

“You’re thinking too hard,” Tristan said. He’d finished drying the couch and was sprawled again, one arm draped over the back of the cushion. “I can hear it from here.”

“I’m not thinking.”

“Your forehead does this thing when you’re thinking. It gets all scrunched up.” Tristan demonstrated, furrowing his brow in an exaggerated impression. “Like you’re trying to solve a math problem.”

“I don’t look like that.”

“You look exactly like that. It’s very serious. Very Alpha.”

Cole reached over and shoved Tristan’s shoulder. Tristan laughed and shoved back, and for a second Cole could enjoy the familiar roughhousing without wondering what it meant. He wanted to keep that ease between them, even if he was beginning to admit that friendship wasn’t all he wanted.

“Are you coming to the meet?” Tristan asked. He sounded as though he’d just thought of it, but Cole knew that deliberately casual tone. Tristan wanted something. He was just pretending he didn’t.

“This weekend?”

“Saturday. Two o’clock. You should come.”

“I’ve got practice.”

“Practice ends at noon. You told me last week.” Tristan stretched his arms over his head, a long, lazy movement that pulled his shoulders back and made the muscles in his chest shift. Cole watched the ceiling. “You can make it. You just don’t want to sit in the stands and watch me win.”

“I’ve seen you swim before.”

“Not this season.”

Cole let the silence stretch. He hadn’t been to a meet yet this semester, and Tristan had just disposed of the excuse he’d been using. Practice wasn’t keeping him away. Watching Tristan swim meant watching all that lean muscle and controlled power move through water, and Cole wasn’t sure he trusted himself to sit in the stands and pretend he wasn’t affected by it.

“I’ll come,” he said.

Tristan’s head turned. “Really?”

“You asked.”

“I ask every time. You usually say no.”

“I’m saying yes.” Cole met his eyes again, and this time he didn’t look away. “I’ll be there.”

Tristan’s grin returned, slower and softer this time. “Good.”

He sounded pleased enough to make Cole wonder how often he’d disappointed him by staying away. Cole had treated those invitations as part of their banter because it was easier than admitting Tristan might actually want him there.

Tristan pushed himself off the couch a few minutes later, yawning, and said something about an early morning session. Cole watched him walk down the hall toward his bedroom, the low-slung sweatpants riding his hips, the towel slung over one shoulder, the damp hair curling at the nape of his neck. He watched until the bedroom door closed, and then he kept watching the empty hallway for longer than he needed to.

He’d wanted Tristan for longer than he wanted to count. It had started small, a flicker of something he’d dismissed as proximity or hormones or curiosity, and grown until it was the first thing he noticed when he walked through the door and the last thing he thought about before he fell asleep. Yet he’d never given Tristan a word or a touch that couldn’t be explained away as friendly.

Their parents were married. If Cole crossed that line, he’d be risking the family dinners, the holidays, the easy affection he’d come to depend on. He’d spent years telling himself that leaving things alone was the responsible choice, the thing a good Alpha and a good stepbrother would do. Tonight, with Tristan’s bedroom door closed and no one left to look away from, it felt less convincing. He didn’t even know what Tristan wanted. He’d never asked, and protecting their family had given him a reason to keep avoiding the question. But Tristan had looked at him tonight as though he was waiting for Cole to ask it.

Cole rubbed his palms against his thighs and stood up. The apartment was dark now except for the lamp in the corner, which cast long shadows across the floor. He walked to the kitchen and poured himself a glass of water and stood at the sink, looking out at the campus lights scattered across the dark.

He could feel the change between them the way he felt a shift in weight before a takedown, the subtle redistribution of pressure that meant the situation was about to move. Tristan was pushing, gently and deliberately, and Cole was running out of reasons to push back. He’d promised to be in the stands on Saturday. For now, that was as far as he could see.

Cole set the glass in the sink and turned off the lamp. The apartment went dark. He stood in the living room for a moment, listening to the quiet, and then he walked down the hall to his own bedroom and closed the door behind him.

Through the wall, he heard Tristan settling in for the night, the creak of the bedframe followed by the soft thump of a pillow being adjusted. The familiar sounds kept him company as he crossed his own room.

Cole lay down on his own bed and stared at the ceiling. The water stain was there too, a smaller one, in the corner above his dresser. He’d been meaning to paint over it for two years.

He closed his eyes. Tristan’s scent lingered in the air, and Cole didn’t try to ignore it.
