Do we have a tag for role reversals? Because I think this is the first time I've seen a student-teacher girls' romance where it's the student that dominates the teacher (boy student and woman teacher is a different matter).
Personally, I don't think it be possible to have a "role reversal" tag. Because so many people are different what with their personalities, background, etc., people can do whatever profession and have whatever personality they may have.
I suppose there could be a tag of "people possessing characteristics that deviate from their archetype" but that doesn't really roll off the tongue :^)
