Once a upon a time, there was a girl named Subaru, well actually, he wasn't a girl, but he looked like one, and then there was this boy, Seishiro, who certainly didn't look like a girl because he was manly and had a big yaoi chin.
What a stud muffin.
Anyway they were very gay for each other and then..um...they were also really kinky and naughty.
Basically, blood and eyes got involved, but in the end, it was all good. Sssssssssorta
