Idk, I'm very open-minded about their relationship. It just depends on what they're portrayed as in songs and unofficial manga, I suppose. For example, Hitoshizuku-P made songs where Rin and Len were siblings, but also songs where they were lovers. In some comic strips/fanart, sometimes they're portrayed as twins. Anyway for me is fine for me :P They're Vocaloids after all. People can interpret their relationship any way they want.
