romance short story heroine sees hero in a mirror

[[deleted user]]

This is a short story. Maybe 10-20 pages, maybe longer but i dont think so. I don't even know where or how I read it.

What I remember is the heroine wants to know who her future mate or husband is, so she looks in a magic mirror, the hero also has a mirror in his room, and sees him...then she somehow goes through the mirror and has relations with him. :) The hero thinks it was a dream until he or his brother finds a long red hair on his person. The hero wants to know who it was. The heroine has a sacred pool, kind of a hot spring and i think the hero sees her there in the mirror. I think she was some kind of priestess. somehow the heroine has to go visit the palace, because the hero is a prince, and sees the hero and tells him they were fated or something to that effect. I believe the hero's mom knows about the mirrors because she knew the priestess'.

I guess this needs to go into the "now we'll never know" folder...
