Does Ceil acculy 爱情 Sebastain, 或者 is he just bio?

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

Her attempts were thwarted when she was turned down 由 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 日本漫画 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~ ^///^
