I listened to This Will Destroy You´s Freedom Blade while writing this. Even though the name of the band don't sound that... fitting or happy, it gave me this sort of soft and calm feeling. Try listening to it while reading it?
Renji smiled as he entered the bedroom. Akaya had obviously exhausted himself while waiting for him to come back home. The bed was a mess, and he guessed that the younger had been rolling around in it for a while. Sitting down on the bed, he watched Akaya´s curled up form, hugging the blanket. They may be a whole lot older now, with Renji now in his second year of university and Akaya who had just graduated and was searching for a job, but Akaya was still the same, so young and childish. He supposed that he hadn't changed much, either. At least that was what Niou said whenever he met the other at university.
He ran his fingers through Akaya´s tangled locks carefully, trying not to wake him. Not that he had to worry, Akaya was a heavy sleeper, at least most of the time. The seaweed head curled up tighter, gripping Renji´s hand in his sleep, making Renji´s smile even softer, softer than he'd care to admit that he was capable of. Not even Akaya had seen those smiles, which was good, otherwise the entire team would have known the day after. He let his still free hand pinch the younger's nose, the younger frowning a little, eyes opening a crack.
"...How'd you know I was awake?" Akaya asked, sitting up, although not letting go of his former sempai´s hand.
"I know you too well, Akaya. Do you know your own sleeping habits?" Yanagi smiled. 'Had you been sleeping, you would have pulled me down and used me as a human pillow instead of just taking my hand.' He wouldn't tell Akaya that, though. It was too amusing to see whatever he would try next. He bent down to Akaya´s level, pressing a kiss to his lips. Akaya wrapped his free arm around Renji´s neck, the older slinging his arm around Akya´s waist and they fell back on the bed. Everything around them was silent, except the occasional sounds penetrating the window glass and Renji left soft kisses all over Akaya´s face. Their fingers intertwined softly, feeling the other there.
