I admit, this is very cliche: but common let's face the facts, it's near impossible to write an original yuri, or an original MANGA IN GENERAL. Yuri writers tend to make the main character start off straight, have a beautiful maiden confess, then "Omigod meh hart wont stahp beetting....?!" However the beauty of these authors is that they all inculcate different implacations, which is why I love yuri so much.
