I didn't understand the ending. What's this obsession about amnesia? Did he died? What happened to Tae Group?
My theory on the ending is that he didn't have amnesia, he just faked it in order to be able to start a new with Eun Gi and i'm quite satisfied with this ending, he looked like he didn't forget her, and Sun_Bird's theory makes sense too so it is a happy ending to me, i refuse to believe that he died and it was just a dream.
