As far as I understand, Harem is about a relationship where MC has more than one girl as girlfriend/wife at the same time and these girls kind of adore him. What about the situation where the MC is admired by one girl and is chasing another girl that don't like him that much? Or if the MC is fooling around with two girls who love him and end up choosing one? Or if the MC is hesitating among three girls who love him until two of the three die? Where is the line?
