@Twi: Farmer boy certainly acts like a Mr Know it All when it comes to Ji-ae. I certainly wouldn't have been as passive as Ki-bum in response to the way farmer boy seemed to think he knew more about the wife in the few days he's known her than her husband. Especially when farmer boy blamed him for the emotional condition the wife was in when she first met farmer boy as if he was part and parcel to the whole affair from the beginning. No, Ki-bum, it was not your fault.
But, yeah, Ki-bum, in his own way, was certainly very much in love with and devoted to his wife from the get-go, but it certainly didn't take Ji-ae long to forget that she was married once she met farmer boy. She's a huge hypocrite in my book. Not 24 hours after she gets angry at her husband because she thinks he's kissing another woman, she accepts an invitation to stay with a man who she thinks is handsome. She takes off her wedding ring so she will appear to be a single woman. She has a fling with the man, going on dates, wining and dining, and not once thinking about her husband. Some devotion to her marriage she has.
