Prompt: Haru wearing Makoto's clothes. Rating T

Neither of them could remember how it had started; it had been like this ever since they could remember.

Whenever one spent the night at the other's house, some clothes would be lent to the guest to sleep in. It was no problem when they were still kids, though Haru was a little taller than Makoto, they fit the same size so borrowing each other's pajamas was easier than bringing a pair of their own.

That was how it always had been and neither had ever questioned it.

Until one fateful day the sight of Haru wearing his clothes made Makoto question his entire existence.

It was a Friday evening and Haru was spending the night at Makoto's house like he did almost every week. After dinner they had gone to Makoto's room accompanied by Ran and Ren, who claimed that they were going to stay up all night with their brother and his friend, yet had fallen asleep before Makoto and Haru had selected which game they were going to play. Not long after that Mrs. Tachibana went to retrieve the two so she could brush their teeth and put them to bed. When she came back about half an hour she told them that the bath was ready for them. Knowing his best friend better than anyone, Makoto had offered Haru that he could go first and of course, Haru didn't need to be told twice. Without thinking he had pulled a shirt and a pair of shorts out of his dresser and handed them to Haru, who wordlessly accepted them and retreated to the bathroom.

So Makoto was left alone in his room and he continued to play a few rounds of the game as he waited for Haru to return.

Eventually Haru came back and Makoto turned his head towards him, about to ask him if the bathroom was free when all the thoughts in his head evaporated into thin air and the world stopped spinning as he laid his eyes upon the familiar figure that was his best friend.

His black hair was damp and tousled by his half-hearted attempts of drying it, his cheeks were flushed red by the steam of the hot water and that made his ocean blue eyes even more vibrant and breathtaking than usual, and though he looked absolutely beautiful right now, that was not what knocked the air out of Makoto's lungs, not what made every trace of his common sense disappear.

The shirt that Makoto had given Haru was too big for him, so big it was sagging off his shoulder and exposed the porcelain skin of his clavicle. It made Haru look smaller than he actually was as he was practically drowning in the material. The shorts weren't much better; the drawstring being the only thing preventing them from slipping off his hips, the fabric covering more of his slim legs than shorts should.

Ever since they had entered middle school Makoto had hit a huge growth spurt that made all of his clothes too small and thus Makoto's mother had taken him out shopping a week prior so he could wear things that actually fit him again. Before he had grown so much all of a sudden he was already a bit bigger than Haru, his clothes a size larger than his friend's so they were a bit too big on his slender frame , but it had never been so obvious. Not so obvious as it was right now.

For the first time upon witnessing his best friend in his clothes, something inside Makoto cracked. A surge of warmth rushed towards his face and his heart and he was overwhelmed by all sorts of feelings that he didn't know the meaning of.

Gaping at Haru like a fish out of water, Makoto was torn between averting his eyes and letting them wander over the beauty that was standing before him. Even though he knew the only reasonable option was the former, there was something in him that made him unable to do so.

"Something wrong?"

The sound of that stoic voice took him back to reality. Immediately he closed his mouth - that had fallen open without his awareness - and turned his head back towards the screen before him, noticing that he hadn't paused the game he was playing and realising how stupid he must have looked.

"I, uh, no, I-" he stuttered, trying to regain his composure, "I-I'm going to take a bath now," he evaded the question, his voice cracking like it did so often lately, which only added to his embarrassment as he jumped up and practically ran out of the room.

Once he was safely inside the bathroom, a deep sigh left his lips. He had no idea what was overcoming him all of a sudden; his heart was beating faster than it ever had, his body was tingling and his head was filled with nothing but images of Haru in his oversized clothes and thoughts of how cute and beautiful his friend had looked. It wasn't as if he didn't think his friend was beautiful or cute otherwise, because Haru had always been good-looking, but never before had it messed with Makoto's brain like it was doing right now. Hell, he had never felt like this before in general, about nothing and no one. Or maybe he had, but hadn't realised it until now.

Was this what it meant to be attracted to someone?

Only when his frantic heartbeat had returned to normal and he had regained somewhat of a composure, Makoto left the bathroom to join Haru in his bedroom. If Haru had noticed Makoto's odd behaviour, he had decided to be kind on his soul and not mention it.

They resumed with their game as if nothing had happened. The only difference was that Makoto couldn't stop his eyes from wandering every once in a while, letting him feast on the view of this beautiful boy in his clothes and along with the knowledge that this beautiful boy was his best friend made a flair of pride mixed with something he couldn't name shoot through his body.

Then Haru caught him staring and looked at him with a inquiring gaze, his eyebrows upturned and Makoto could read the same question he had asked before in those vivid eyes.

"It's nothing!" Makoto tried to brush off as blood rushed towards his cheeks. The pride he had felt soon changed into embarrassment and shame at being caught. Knowing he needed to recover himself, he explained, "I just, I was thinking that maybe you should bring your own clothes next time. Since mine are so big and all. I mean, that can't be comfortable right?" He had attempted to sound as nonchalant as possible, but it wasn't entirely working. Lady luck was not on his side tonight.

"Hmm." This noncommital hum was all the response he got, but knowing Haru, it was the best he was going to get.

Not a single word was spoken about the matter after that. Makoto did his best to get his mind off of this revelation of his and focus on the game instead, but it wasn't easy considering Haru was sitting right next to him, their bare knees touching.

It was hard, but eventually Makoto managed to drop the subject in his head and the night proceeded without any other hiccups. Now he just hoped that Haru would do as he had told him and would bring his own clothes the next time.

But Haru didn't. Every sleepover at the Tachibana residence that followed afterwards, Haru arrived without any clothes of his own, which left Makoto no choice but to lend him some of his own. He never commented on it; nothing was ever mentioned about that one night again.

At the time Makoto saw this habit of theirs as a curse disguised as a blessing, for knowing someone so gorgeous and captivating was sitting right next to him, wearing his clothes, but not being allowed to stare felt like pure torture, and this thought made him even more embarrassed about the whole thing than he already was.

As time passed and their relationship progressed, Makoto's opinion slowly changed and he began to acknowledge how much of a blessing this childhood habit of theirs actually was. He no longer felt flustered when he saw Haru in a shirt that was his or a pair of his shorts that was so big on his lithe body that it was exposing his hip bones. Of course, Haru still looked absolutely adorable and beautiful, that would never change and Makoto enjoyed every second of seeing him in his clothes. But rather than embarrassed and flustered, he now felt proud.

Proud that he was allowed to call someone as amazing as Haru his boyfriend.
