Super Lovers

If you're a SebaCiel shipper like I am, then Super Lovers is the closest you're going to get to SebaCiel being canon. The teenage protagonist (Ren) looks eerily similar to Ciel, while Haru is absolutely eye candy, just like Sebastian. There is also a power struggle between the two, just like there is between Ciel and Sebastian (even though his contract states he has to obey his master, no matter what).
Just take my word for it and watch Super Lovers.
