So, this is a little thing me and Admirer decided to do with Sunshine and Aqua on a moment during their separation from each other. It keeps shifting between 3rd person POV focus, so please keep this in mind as you read.
Aqua
Aqua was looking towards the paintings in front of him while a surge of emotions and memories passed through his very soul. Each and every one of them was by him on his own, and each and every one showed the portraits and illustrations of one certain being, the same being he lost his heart to, the same creature he was missing so much right now.
If it wasn't for her memories, he'd never had gotten free from his beastly side and would never have considered that he could be a better pony like he wanted to be.
Sunshine
Sunshine sighed aloud as the last of the suitors had been sent away, sitting upon the throne once used by Princess Celestia perhaps no less than three or four years ago; now she was the one who wore her crown and it was her duty to pick up where her mother had left off. Naturally, still being quite young, she had been visited by many suitors who hoped to gain her hoof in marriage if only to be by her side and share her status of royalty. She had sent them all away, for even though some did have good intentions for asking, they didn't hold her interest.
She never told them, but the real reason she sent them all away was because she had already found her true love once, and he was now in a world far from her own. She had promised him that she would wait, and she was determined to wait it through, knowing that one day he would return.
Aqua
Aqua, when he couldn't hold back, floated a painting in front of him, in which he had drawn an illustration of her beautiful face, as if she was looking towards him while there was a pleasant, yet sad smile on her face. This reminded him of the moment he had seen her last. Tears were threatening to leave his eyes as he felt an urge to nuzzle her portrait in front of him.
Sunshine
Sunshine looked out at the land of Equestria below her as she slowly lowered the sun using the magic Celestia had given her before her death, watching it sink below the horizon and then shortly replaced by Luna's night. As she turned and entered the throne room again, it brought back a memory to her that always seemed fresh on her mind at the end of the day. Their last night together, within this very room. The Changeling gave a sad and heavy sigh, as silent tears started to fall from all eight of her eyes.
*Incoming Song*
Aqua sighed deeply as he felt his tears falling and his horn ceased to glow as he slowly hung her portrait on a wall in front of him. Aqua started to sing a song through the melody he felt in his heart, as he felt some warmth in his heart at the hope of seeing her again.
Aqua: I promise that one day I'll be around
I'll keep you safe, I'll keep you sound
Right now it's pretty crazy
And I don't know how to stop or slow it down
Hey!
I know there are some things we need to talk about
And I can't stay
So let me hold you for a little longer now
Take a piece of my heart
And make it all your own
So when we are apart
You'll never be alone (x2)
Meanwhile in her own world, Sunshine looked out at the star-filled sky as she felt a melody inside her own heart while she stared out at a particular star out of the rest of them. A slight insect hum was heard from her and she began to sing as well.
(Just before her part): You'll never be alone
Sunshine: When you miss me close your eyes
I may be far but never gone
When you fall asleep tonight
Just remember that we lay under the same stars
And hey!
I know there are some things we need to talk about
And I can't stay
So let me hold you for a little longer now
And take a piece of my heart
And make it all your own
So when we are apart
You'll never be alone (x2)
(Alternating between them): You'll never be alone (x4)
For whatever reason that night, it was as if they could feel each other's presence as they continued to sing, giving them a comforting sensation as a result as they finished.
Both: And take a piece of my heart
And make it all your own
So when we are apart
You'll never be alone
You'll never be alone...
Aqua wiped his tears and went out of his room as he trotted towards the balcony of the Palace, and soon he was under the starry night of his grandma Luna. He looked towards the sparkling blue sky as he once again thought of being in her warm embrace. Meanwhile, Sunshine had done the same and was staring out into the night, remembering his touch and the kisses they had shared while they were still together.
As they stared out at the stars, both seemed to notice a single star in their world that shone in a particular manner. Somehow, they each knew that star was truly something more, and it made them feel a bit closer to each other for one brief moment.
Aqua was now found once again lost in thoughts and he closed his eyes, as he began to feel as if he was holding her in his hooves while her lips were touching his own, and that feeling gave him enough warmth to keep standing there during the beautiful yet cold night.
Sunshine almost felt as if he was there in the flesh, holding her close and providing her with the safety and closeness she enjoyed so much. Her could almost feel his lips on her own, and it made her feel for a moment that she could feel his love flow through her again like it always did. She sighed and a small hum came from her.
"I miss you so much, my prince," she whispered aloud. "But no matter how long it takes... I will wait for you. Just as I promised."
Aqua opened his eyes as a few sobs escaped him.
"I'll return to you, my lovely Princess," Aqua said, looking towards the sky. "I'll be there right by your side, once again... no matter how long it takes."
They stayed there in silence for a moment longer, then both slowly left the balcony and trotted back into the palace. While trotting back, they sang the last verse one final time, slower.
Both: Take a piece of my heart
And make it all your own
So when we are apart
You'll never be alone.
They each reached their bedchambers and crawled into bed, breathing out their last parting words as sleep quickly overcame them.
You'll never be. Alone...
Gosh, this was sad to make! Those two honestly are the best collab shipping couple I've ever worked on so far!
Song used: "Never Be Alone" by Shawn Mendes.
