Love triangles can either be relatively balanced, in which the two candidates each have a fair chance of ending up with the protagonist, or they can be lopsided, in which the hero or heroine has an obvious romantic interest in one of the candidates, and considers the other candidate as "just a friend", but withholds a confession to avoid hurting feelings. An example of this is in the Broadway hit musical "Wicked", in which dim-witted Fiyero first displays affection for Glinda the Good Witch, but then falls for Elphaba, the supposedly Wicked Witch. But in this latter case, to provide necessary tension and drama, the second platonic candidate is also very often the hero or heroine's long-term boyfriend or girlfriend.
