SebaCiel. PG13 is my guess. Modern AU.
Having been forced to grow up quickly after his parents' abrupt death on his tenth birthday (and his subsequent kidnapping), Ciel Phantomhive is a mature, intelligent young man at just fourteen - but almost fifteen. He lives with his slightly distant Aunt Angelina, and he attends a very prestigious school for the arts - Victoria's Institute.
Ciel hoped to, one day, be principal of Victoria's Institute, just as his father had been before his death, and his grandfather and great-grandfather before him. However, at the moment, he was very far away from his goal, as he couldn't even get the lead in the school play, much less lead the entire school.
All he wanted to do was bring back honor to the Phantomhive name, but for now, he would have to settle for showing the petty children at Victoria's Institute for the Arts who was really in charge - including a certain smug, red-eyed boy named Sebastian.
A Maybank and A Cameron? It's almost like a modern Romeo and Juliet. It's forbidden for them to be together. Could be the end of the world.
The stolen glances, the hidden feelings, the unspoken words, the secret meetings and the obvious hatred towards each other followed by constant conflicts and some hidden past that threatened them but there are always invisible strings tied and pulling them together no matter how hard the tides trying to pull and part them away from each other.
