I saw the ending too. Didn't get much. So he killed himself. But that isn't important since he was the bad guy and I can understand why he had to die. If I watched this all I would probably be happy too. Anyways the problem is if she ends up happily. The lead girl. But it doesn't seem so and she has no love interest she's with either so I'am gonna skip this drama.
I am sure if I wait long enough (like a yr) I will either be able to watch it subbed or be able to understand enough Korean to watch it w/o the subs. Either way I will end up watching all 120 (omg extremely long) episodes.
