Forbidden

He knew what they had would be forbidden should any one find out before Harry was seventeen. Even then society would frown on them. Two heirs from old pureblood families, one of them the only surviving member. A Slytherin and a Gryffindor would probably cause as much shock in the community, especially that Gryffindor.

No they would have to continue being a secret no matter how much he hated it. But then again that which is forbidden is always better.
