Izuku was curled up into his boyfriend's chest, head nuzzled into the dip between his pecs and legs twisted to rest comfortably between his knees. He kept his eyes closed as Katsuki absently played with his hair, curling a finger around his curls, occasionally dipping down and placing his chin on top of the unruly mop. The movie played, some sci-fi thriller that was the first thing that popped up, but neither boy was watching. They were perfectly content in each other's company.

It was a Sunday, and since Katsuki's parents weren't home they had decided to crash there, have some quality time together, since it had been in short supply recently, what with their hero training and school work. Most of their weekend had consisted of lazy days snuggled on the sofa, except that morning where Katsuki had insisted they go for a run, despite it being November and very, very cold.

For maybe the fifth time in the past half-hour, Katsuki's face nestled into Izuku's hair. Izuku laughed under his breath.

"What?" Katsuki asked, sounding vaguely offended as he withdrew, fingers trailing up and down Izuku's arm.

The corner of Izuku's lip quirked upwards as he shook his head. "It's nothing."

Katsuki frowned, fingers grasping at Izuku's chin to turn his head to face him. "Well, now I just want to know more."

Izuku laughed again, more audibly, leaning upwards to try to kiss his boyfriend. Katsuki, still frowning, pulled away, not wanting to give him the satisfaction of a kiss despite craving it himself. "Nuh uh. Tell me."

For a moment Izuku just pouted, giving the blond puppy eyes that Katsuki avoided. Izuku rolled his eyes, slumping back into Katsuki's chest, still chuckling to himself. "I just had a silly thought, is all."

Bringing a hand up with the intent of threading it through his hair once more, Katsuki hesitated. "What kind of...silly thought?" His fingers intertwined with the green locks, soft beneath his calloused skin, a delightful sensation Katsuki had began to look forward to feeling. It was calming, in a way.

Izuku hummed, the sound low and vibrating against Katsuki's chest. "I just wondered what I smelt like."

A bemused expression appeared on Katsuki's face as he stopped threading his fingers through the strands. "You what?" he asked incredulously, frowning.

Izuku shrugged, tilting his head to peer up at the blond through thick, dark lashes, a light dusting of pink adorning his face. "It's just interesting, you know? You have such a nice smell, like...caramel, and dry wood, but I've never been able to pinpoint my scent."

"Tch." Katsuki looked away. "You smell nice, I guess."

At those words, Izuku perked up, squirming to spin and face Katsuki. "Really? What do I smell like?" He was smiling, hands resting on Katsuki's shoulders for balance due to the precarious way he was sitting.

"I just said it was nice, didn't I?"

"But that's not describing it!"

"It's nice!"

Izuku sighed, head lolling to the side in defeat, collapsing into Katsuki's body and flopping onto the armrest of the couch. "You're so difficult sometimes, Kacchan." And although the tone was warm and loving, just teasing him, Katsuki immediately took it as a challenge, as his rather large ego tended to in most situations. He hooked his arms underneath Izuku's, the greenette lazily glancing up at him with a questioning look which wasn't answered, and hauled him up. Burrowing his head into the crook of Izuku's neck, Katsuki inhaled, breathing in the smaller boy's scent.

Izuku chortled to himself, wondering how the blond managed to do so angrily, but didn't resist. He knew little tips and tricks to twist Katsuki into going along with things. It wasn't manipulation, just...observation.

After a moment, Katsuki grunted but said nothing more.

"Well?" Izuku pressed impatiently, his voice tinted with concealed amusement as he desperately tried to suppress a grin, failing miserably.

Katsuki chewed on his tongue for a moment. "You smell..." he paused, as if searching for the right word. His face cleared. "Healthy."

Izuku snorted, jerking upright and losing his balance, toppling off the sofa and onto the floor, his head missing the edge of the coffee table by less than an inch as he howled with laughed, rolling about on the carpet.

Katsuki just looked annoyed. "What?" he demanded, half-heartedly kicking Izuku in the side.

"H-Healthy!" Izuku managed to say through his hysteria, arms clutches around his middle as tears began to roll down his face. Not impressed, Katsuki simply kicked him again. Izuku didn't seem to notice, completely preoccupied with his laughter. Katsuki decided to ignore the hysterical boy on the floor and watch the movie, despite not understanding the plot in the slightest. After a minute or so, Izuku's guffaws turned to giggles, then to suppressed snuffles, then eventually silence, which was followed by Izuku tugging on Katsuki's trouser leg. Katsuki ignored it.

"Kacchan?" Izuku was pouting again, bottom lip jutting out in a way that made Katsuki want to kiss him. "Don't be mad."

"I'm not mad," he denied instinctively, still not meeting the greenette's gaze.

Izuku huffed, then clambered back onto the couch, curling into Katsuki's side, lifting his arm then dropping it so it draped over his body. He seemed to hesitate, then he grinned. "How do I smell healthy?"

Before he had even finished speaking Katsuki was growling. "Doesn't matter," he muttered, scowling.

Izuku made a soft noise that Katsuki couldn't tell was one of laughter or disappointment. He pushed himself up with his elbows, turning to press his face closer to Katsuki. "Please tell me. I promise I won't laugh," he tried, giving him the puppy eyes again.

Katsuki, not having to chance to hide, got a full blast of the effect and gave in immediately. "Well," he began slowly, keeping his words evenly spaced, thinking of the best way to phrase it. "You smell like fruits. Like...peaches, and blackberries. You smell clean too, like you've just washed in the purest stream in the world. And...you smell like home. Like you're good for me."

Katsuki hadn't realised that he had closed his eyes part way through, so he opened them, only for fiery crimson to meet teary green, salty water collecting in the corner of each eye as Izuku's face crumpled. His arms flew around Katsuki's neck as he hugged him, clutching him tight. "Kacchan!" he cried. "That's the nicest thing you've ever said to me!"

Katsuki blinked, wondering if that was true whilst simultaneously running through all of their interactions in his mind, when Izuku pulled back and pressed his lips firmly against Katsuki's. It took the blond a moment to understand what was going on, but when he did he kissed back, just for a second, before pulling away, smirking. Izuku was still crying a little, so Katsuki wiped away the tears. "You don't need to cry all the time, Deku," he said lovingly.

Izuku smiled through the tears. "But I'm a cute crier."

A pause. "You've got me there," Katsuki conceded, caressing the boy's jaw softly with a single finger, enjoying the tingling sensation it sent up his arm. Izuku closed his eyes, clearly feeling something similar, and he leaned in, closer until he had his head buried into the crook of Katsuki's neck, content in his bliss.

That is, until the front door practically flung off of its hinges and Mitsuki Bakugo stormed in, suitcase in hand, causing Katsuki to lose his calm and push Izuku off of him, proceeding to have a shouting match with his mother while Izuku and Masaru watched on the sideline, sharing a knowing look as they watched their individual lover's yelling intensify in volume.
