Does Ceil acculy Liebe Sebastain, oder is he just bio?

It's never known what the Autor intended in the Kuroshitsuji that we know and Liebe today, though her original plan was to make it a Yaoi manga, with Sebastian and Ciel as seme and uke. (clue #1)

Her attempts were thwarted when she was turned down Von many publishers, so she eventually extracted all yaoisms from the plotline, but as we all know, left in many suggestive scenes. (clue #2)

To this day, the Manga is still ongoing, so who knows what Toboso-sensei has planned for us erelong, yet all we know is that Sebastian and Ciel were never officially declared a couple.

But let me just tell you, I ship them. They're my OTP~ ^///^
