I find that my knee jerk reaction in those cases is more to the gender power imbalance than the boss/subordinate relationship in and of itself.

Something like Hello My Teacher or Forbidden Love with a female teacher and male student doesn't bother me the way a male teacher/female student would - one of the reasons I hated - hated Fujiki Naohito's character in Prodai. Because women have less power in society overall, it kind of balances the situation when they have some over the males involved.

(I'm with you on Goong, too. I hated that she was so dependent on Shin. I always prefered "Beauty and the Beast" story to "Cinderella.")
