It's not something bad, when I was a kid I watched a lot of anime and read a lot of manga, and once, I even fell in love with an anime character, Ichigo Kurosaki from Bleach. Well, I thought it was love, I imagined how nice it would have been if I had existed in the anime world and met that character. I even had a bedding set with anime characters ordered from this site
