Hello fangirls and fanboys of the Yaoi Genre. Let's hear your favourite titles. What makes them so awesome? Rating? Is it something that is NSFW so we have that warning before going and searching it? What is the main couple? Why do you love this so much? What type of pairing is it? Are they the famous Japanese Oil and Water couple? Let's hear your favourite Yaoi. If you can guess my favourite Yaoi, I'll give that person 5 million gold. First person to say it first will win though so be quick!
