This drama really super is on the cutting edge for examining the social, emotional and physical relationships that exists between two adults. That relationship is expanded by the interaction with friends, co-workers and even parents. It also is realistic because in most long term relationships there are interventing circumstances that will change the "love story" of the adults involved. This drama has a good depiction of murphy's law. Everything possible started to go wrong because of one intervening party's opinion. I call in "enlightenment" combined with lust (initially).
