Your Windows desktop image is a Duo picture. You carry a picture of Duo in your wallet and tell people he's your boyfriend from America. You wish Duo would come out with his own line of products, so you can use the same shampoo and toothpaste he uses. You cry when people say Duo isn't real. One of your hobbies is flaming Duo-haters.
Duo ever needs surgery.
You begin to think that you and Duo are somehow related. Your teacher asks you to write an essay on a famous person, and you choose Duo. You look everywhere for violet contact lenses. For your art class assignments, you always draw Duo. People who haven't even watched Gundam Wing know who Duo is, thanks to you.
