Koyzana, you are just a dictionnary of yaoi, we can ask you anything you will find it haha.. and then I considered myself reading a lot, but I cant compare to you hehe ╮(￣▽￣)╭

You praised me too much. (●'◡'●) I believe there're many people here read/know more than me. But we just read different manga, so mangago front page is a good place to exchange the interesting manga.
