No it's not unhealthy. toi can be obsessed with anything. I'm obsessed with Law & Order:CI. I have way plus than six pictures of the characters and I write fanfiction. If toi start écriture Alvin and The Chipmunks fanfiction, toi need to worry. LOL
no. It's normal. my friend is MAJORLY OBSESSED with them, but ur normal compared to her. most of the pics on my firle are of Sailor Moon, but im not obsessed. If toi become MAJORLY obsessed with them, than its unhealthy. try to do other things and like them. That's what my friend did. BTW, I also like simon!
