You know you're obsessed when...
heart you get the music stuck in your head during school and start humming along
heart you get hyper just thinking about an anime/manga character
heart when you download all the music because you like it
heart when you read/watch it more than once
heart when you get an many pictures as possible and make a folder on your computer
heart when you reread you favorite manga's and can hardly look at it after shouting out the characters name and then hyperventilating
