Hogwarts 2003 is a role playing game. It's characters are represented by celebrities but please note that they are not the actual persons. Merely physical representations. It is based in the world of the Harry Potter book series, but does not include any of the characters except in hearsay.
As such you should know that Hogwarts 2003 is open to all relationships (M/M, M/F, F/F), in fact, the diversity is overly welcome. If any of this bothers you then perhaps this is not for you.
