it would've been really better if she was single, or has just broken up, or the oppa broke up first. but suddenly breaking up with your bf coz you are attracted to your friend's dick...doesn't sit right with me. if her feelings were swayed or she no longer liked the oppa then that would've been fine too. but then again, keeping up the relationship when you are constantly thinking about other man's dick is also cruel to oppa. ugh...this is really conflicting and i feel bad for the bf.
