Written for perpetualxlight's birthday, her prompt being "rain".
Rainy season had begun, and the world was a sodden place.
From his seat on the steps of the porch, Riku quietly watched sheets of rain splatter onto the ground, trickling down rooftop gutters and dripping from leaves, and collecting into puddles in front of him, forever distorted by tiny ripples, brief reminders that raindrops ended their journey there.
There was the sound of a little rivulet bubbling, accompanying the wet pitter-patter on the roof above.
Beside him, close enough to feel his warmth, Sora was humming, tapping his bare foot against the wood vaguely in time to the tune.
"That's from the Symphony of Sorcery, wasn't it?" Riku murmured. There was a tingle in his chest, like his heart was humming along too.
The humming stopped. "Yeah. From when our Sound Ideas joined." Sora grinned and reached a hand out to feel the rain hitting against his palm. "It kinda stuck around in my head."
"Mickey… Mickey told me that it was our hearts singing, because they were always in tune."
"A song that our hearts made together, huh? No wonder I couldn't forget." Sora said, smiling. He retracted his hand and wiped the water off on his shorts before he reached for Riku's, tangling their fingers together. "What do you wanna call it?"
Riku let his other hand rest on top of Sora's, and said, a little bashfully, "Dearly Beloved."
Somewhere amongst the rain, the faint melody of a piano could be heard.
