>Heck, if anything, in my head they're meeting and hanging out, becoming new friends, and the like.
This, my waifu is not a vocaloid but I do enjoy listening to Hatsune Miku and Gumi, I do acknowledge such vocaloids are cute and thier music is good, but the feelings I have for my waifu don't even come close to what I have for them.
It used to bum me out that I'm spending time listening to vocaloid rather than my waifu, but I realized my waifu can enjoy such songs too, then I imagine us both sitting together listening to Vocaloid, talking about the songs, and even dancing with them toghether. Same logic applies with movies, video games, etc.
Now I don't think our relationship could get any better, but you never know, the more I spend time with her, the more I'm surprised.
