This handbook is specially written for those who are scared of ever becoming an ONLPF (Obsessed No Life Psycho Fan) and would like to stay sane. Or for those who just entered the Backstreet World (yes, there still are fans like those!) and have no idea how to become sane (and with that, stay sane).
Here a few rules. Yes, rules. If you want to become and stay a sane fan, you have to obey these rules.
