This is a list of oneshots that I made a while ago, so I hope you enjoy this.

Disclaimer: I do not own Vocaloid and I do not want to get sued by Yamaha, but I don't know if they would hate that.

Warning: Contains Twincest, they were little kids, and they didn't knew that it was wrong.

Soulmates

Rin's POV

I like this life.

But I know that the timer is about to run out as soon as Mr. black cloak comes for a visit. My little brother Len usually goes outside to see his friends, but he does his best to spend time with me the most.

"Rin! You're still okay!"

This is what I'm greeted with every time. We were both the age of 6 during that time. He didn't know that I would fall into a deep sleep or what mommy would say, "You will die."

"Why do you always get to stay in bed? You always get the most attention by mom all the time!" He whined at me. He always thought that I get sick on purpose just for mommy and daddy. So they would buy gifts for me.

I shrugged at him as he crawled next to me on my bed. "I don't know, Len. I don't even need them anyways," I frowned at him. He was already holding a picture book, so he could read me a bedtime story.

It was about sleeping beauty. Len and I both liked that book. He reads it to me every night, which made me happy. "Don't you think it's cool?" he asked me. "What is it that's cool?"

"Once you fall asleep, I'll be the one to wake you up!" He beamed at me. To be honest, it sounds kinda gross before, but I agreed to it, hoping I won't sleep forever. "Pinkie promise?"

"Yep! I promise."

We pretty much promised that we'll be the ones protecting each other until the day we die. That's what I believe it means. The next day was the same. Mom and Dad kept giving me gifts so they can entertain me, my little brother going outside to see his friends only to come back to play with me.

The only difference was the fact that time was running out. I was going to die.

Then there was the time when the cloaked man was about to come to take me while I was having my last moments with Len.

"The end. What did you think, Rin?" Len closed the storybook and looked at me with the same excited eyes, waiting for my answer. But I couldn't respond to him. I felt so weak that if I speak, he'd be worried about me.

Then I remembered the promise we made.

"Yeah... I... like it.." I smiled at him weakly. He thinks now would be the time to wake me up when I go in a night of eternal sleep. I felt scared at the time, and I didn't want Len to leave me.

"Len... I'm scared... You're gonna bring me back... right?"

Len stared at me and smiled, "Of course I am! That's what a prince would do!"

"Okay... goodnight."

I feel so weak and scared. But I felt hopeful that Len would save me before the black cloak man takes me away.

I fell asleep. It took a very long time until I woke up. Feeling better, and I can float? I looked around and noticed a girl sleeping with Len. It was already morning, and Len woke up to see that girl on the bed.

"Rin! Are you awake?" So... the girl he's talking to is... me?

But if that's me, then where am I? I don't understand at all. I don't get it...

It's time for you to go, Rin.

I turned around to see the black-cloaked man.

"Oh. You're still asleep?" Len looked at me. Or the body and gave it a kiss. I should be awake, right? So why am I not there?

"Wha... Hey, Rin, wake up! I thought you would wake up once I kiss you!" Len's now panicking.

It hurts to see him like this.

I want to wake up from this.

"Mom! Dad!" Now he's calling mommy and daddy.

You don't need to see this. It's time to go. You'll get to see your friend someday. I turned back to the Black cloak. Was he telling the truth? "You...You promise?" Well, if you wish that, then it's a promise.

"Why, Rin? We promised!" Len sobbed. "Y-You didn't have to die!"

I don't want to see him this way. I want to comfort him just once before I go.

"Bye-bye, Len. I'll see you someday," I said as I wrapped my arms around him while he was crying. For a few seconds, we stayed like that until I let go. I gave one glance at him and walked away with the black-cloaked man.

Another life... Is the time they would meet again...

Len's POV

It was the same as always. A sixteen-year-old boy, fooling around with his friends like it was nothing.

One of them is Miku, who I always get rejected by her like it's not that big of a deal. We're waiting for the new kid to come out so we can hang out.

"About time, Rin! What took you so long!?" Miku yelled at the top of her lungs

Why does that name sound familiar?

"My hair got tangled by my cat, sorry about that." The girl, who I assume is Rin, responded to Miku. The moment she looked at me, it felt like time has stopped.

Why does she look familiar when I haven't met her?

"Len! What are you doing staring at Rin like that?" Miku snapped me out of my thoughts as she waved a hand on my face, "Don't tell me... Is it love at first sight?!" She asked me.

"No! You know I only lay eyes on you, Miku-" I denied

"Nope, I'll pass. I'm not dating you anyway."

"You two get along well."

"No, we don't." Actually, we do.

"What are you waiting for? Let's go already," Rin called us to get going.

So, I really was thinking about some things...

This was a one-shot I made on wattpad, and I decided to add this to Fanfiction, and then I realized how much I hat my writing lmao

(This may be apart of this mystery thing I liked to talk about. So I find it cool to finish that one at the year of 2020, when I was just a baby to the fandom.)

The next one is obviously gonna be how I headcanon the vocaloids.

So for now, see ya
