I have never cried so hard while watching a drama episode, maybe for a movie but not a mere episode, my bad, make it two episodes: Episode 12 and 17. I was so anxious to watch episode 17 that I even watched the raw unsubbed version but I still cried, even more after the subs have been released.
Its been a while since I wrote an episode summary/review, so I will try my best to put important details into it. Like I said I will write one for dramas/episodes that I liked and loved. This one is on the top along with Episode 12.
Before we go to episode 17, let me just have a brief recap of what happened since episode 12. If you can remember in Episode 12, Gun decided to end their relationship without telling Mi Young the real reason behind it. This made Mi Young hate and avoid him even when they had to work together for the company. Episode 12 was probably the most important episode of the drama since it was then that we can see that Gun really loved her but does not want to hurt her when the time comes he die because of his disease. It's a selfish stupid thing to do and all throughout the following episodes we see both of them suffering and trying to sort out or hide their feelings for each other.
