My only regret is they didn't let us know what happened to Hee Moon Jung's character. I enjoyed her in this as much as Yuhee in My Sweet Seoul. Other than that, very good drama with an ending that was consistent with the story.
I love the drama the ending made me mad but I got it she is waiting for him trying to be happy like he told her in the episode 15 he siad "I didn't know someone could be happy just by waiting for someone." she's happy waitng for him.
