Say what?!

That is going too far the big reveal at the end! I felt for Sung Gi but now he's Min Gyu? He said he wanted to be his hyung not be him! Why did he agree to such a thing!!! I am disappointed.

I feel so bad for Min Gyu like he doesn't already lack parental love as well as having a terminally ill girlfriend but his parents basically completely erase his existence! I like Ara for being the strong female she is but that is going to far to even replace your own son! He may as well not have been born poor Min Gyu!
