[Please read everything]
I saw what you said in your description in
[link] And I agree with you completely
Well, I do like Len and Rin together. And the subject I'm about to tell you is about them. No I am not convincing you to like them, I'm just telling you a little information about them.
Here goes: Len and Rin are NOT twins. They are mirror images. Their last name says it all, Kagamine.
Kagami = mirror
Ne = Sound
Rin represents right and Len represents left. I hope that clears this up for you
I love Miku x Len as too and also Rin x Len ^^
