I agree wholeheartedly. I have no qualms with the ending and the fact that they didn't end up together, I'm just ?? at Hee-do for choosing a man for her husband with the same qualities that made her break up with Yi-Jin. She deserves someone present for her. I think the scriptwriters perhaps just didn't care too much about her future husband; they wanted to obscure his identity and "abroad" was a valid excuse, I suppose. (The soundtrack was excellent.)
