YUS, BEHOLD, It's the fabulous Nakamura twins, Emi and Emito~! XD
It's the cantarella versions of them
I swear, I'm ADDICTED TO THIS SONG~
All three versions I love!
Especially Gackupo's(which is saying a lot for me, since I don't listen to gackupo a lot)
What can I say?
I'm a sucker for GackupoxRin XD
And GackupoxLuka
Why I like GackupoxRin I have no idea, probably started liking it after hearing Gackupo's version of cantarella because Rin sort of sang in it too(if you listen closely enough, you can probably hear Rin's voice in some parts of the song)
And I love Gackupo's and Rin's version of Yume Miru Kotori(I LOVE THAT SONG TOO~)
Oh, and I just listened to the parody of Cantarella today, "Shotarella" XD
I swear, I couldn't stop giggling while listening XD
There's something about the lyrics that make Shotarella so funny XD
And here's a link to the song if anyone wants to hear it: http://www.youtube.com/watch?v=0hZhZQBscy4

Soo, yeah, I know, couple of mistakes, yeah. And I think I have an interesting Cantarella story for Emito ohoho~ and yes, it involves Rin XD(For those who don't know, Emito has a big crush on Rin, but Rin doesn't love him back)
So, the Nakamura&Kagamine twins have known eachother almost their whole lives. Emito starts to have strong feelings for Rin, and Emito finds out his sister and Len have fell in love with eachother. Now, while Emito is happy Emi now has a meaningful relationship with Len, he wishes that he and Rin could love eachother as much is Emi and Len do.

SOOO, one day Emito takes out a bottle of some drink(the same whatever Kaito gave Miku in his version), invites Rin over to his(and Emi's)garden for some drinks. After Rin falls unconcious and Emito holds her in his arms, Emito has a feeling that he accidently killed Rin and starts crying. But THEN, Rin wakes up and wipes away his tears. Then the two get up and Rin lets Emito kiss her hand. Emito takes her hand and kisses it, THEN they kiss eachother.

THE END

Wasn't that exciting? :D
