Best Friend's Brother (Kagamine Len x Reader)

You have been best friends with not only Kagamine Rin, but her twin brother, Len. The three of you have known each other since you guys were kids and now in high school, you all have changed in not only appearances, but in personalities too.

But something doesn't feel right. You can easily tell that whenever you are with Len alone, you suddenly feel the awkwardness and odd tension grow more and more constantly. And that's not all; you can't help but find yourself admiring Len sometimes. It is possible that you have feelings for him but is it possible that he likes you back? Would Rin accepts this as your best friend?
