A/N: My first fanfic. Don't know how horrible it is. But... YOLO! Disclaimer: *cries in corner* I don't own Vocaloid... Screw you Crypton...

The first thing I see when I wake up: Len's face, smiling at me. The last thing I see when I go to sleep: Len's majestically drooling face. The things in between range from the best things ever to I want to shoot myself. And right now, I, Rin Kagamine, want to shoot myself. Actually, call the shooting squad. Tell them I'm ready. Because today, my non-sibling and crush, Len Kagamine, got a girlfriend. And even worse, she has long hair. She has a deeper voice. She isn't short. And she had only known Len for a couple of weeks, apparently, before they started going out. I have known Len since we were 1! I took baths with him! We sleep in the same freakin room! And now, Len has a girlfriend. His voice gets me out of my thoughts.

"Rin! Come down! Tei is here!" he calls, and I get up, taking a deep breath.

"Okay! I'm coming!" I respond, checking myself in the mirror. Same short hair. Same high voice. Same shortness. Same old Rin, stuck in the friendzone. I open the door, sighing, and head downstairs, where Tei Sukone, stands with Len. And Len is smiling. I think my heart is cracking.

"Rin, meet Tei Sukone, my girlfriend." At his words, my heart cracks in two.

"H-hi!" I say as cheerfully as I can, because I'm totally not ready to break down or smash my head into the wall. All Tei gives is a nod. Len continues.

"We're going to the movies. We'll be back at 7, ok?" They turn and leave.

My heart just crumbles. He didn't even say goodbye! Len Kagamine, the kid who I grew up with, had always given me a hug and a nice, "Goodbye Rin. See you later." I bit my lip, and keep in the tears. Then, I have a flashback. We were 5. We were outside, and I had just fallen, and scraped my knee badly. I had started crying, when Len raced over me with a pink band-aid. "Rin! Oh no!" he said, bending down and wiping my tears. "Len!" I had cried, crying. "It hurts!" "Here, I'll fix this." He said, bending down next to me. He kissed my knee, and put the band-aid over it. Wiping the rest of my tears, he smiled and hugged me. "See? There. I saved you, princess." I had smiled back. "I'm your princess?" I had asked. Len, a little red now, nodded. "You'll always be my princess, Rin." he said, grinning. I held out my pinky. "Pinkie promise?" I had asked. Len nodded, wrapping his pinky around mine. "Pinkie promise," he had said, hugging me again and taking my hand. When I remember this, the promise we had made, I can no longer keep in the tears. I run out the door, and over to Miku's house, which is three seconds away, and burst into her bedroom, finally breaking down. Miku jumps off her bed and races over to me.

"Rin! What's wrong?" she asks, hugging me and patting my back soothingly.

"Len got a girlfriend!" I cry, sobbing. Miku keeps patting me.

"When you're ready," she says.

Len POV: "Rin, meet Tei Sukone, my girlfriend." I say, motioning towards Tei. Funny. Saying that Tei is my girlfriend feels foreign to my tongue. I shrug it off. Maybe I just need to get used to it.

"H-hi!" Rin responds, and for a second there, I think I see her smile falter for a bit. I shrug that off too.

"We're going to the movies. We'll be back at 7, ok?" I say, and Tei and I leave. We are about halfway down the block when I remember that I never said goodbye to Rin. I turn around, but then I see Rin run out of the house and into Miku's. ... Was she... crying? Tei's voice brings me back to her.

"C'mon!" Tei says, stomping her foot. I nod, catching up with her.

"O-ok.." I say, shrugging off Rin again. After all... Rin couldn't possibly be crying...

A/N: Not going to make Tei a yandere this time... I don't think... Anyway.. Was it good? Horrible? Some crap you never want to see again? I hope not... T^T Anyways, till next time! Stay Awesome~ PieGuavaXD
