Kim Shin or Se Joo? Who will Mi Rae marry?

I was a little bit disappointed about the ending. The story left me a room to think about what would be Na Mi Rae's choice in the end. Will he choose to be with Kim Shin or will he choose to be with Park Se Joo? Probably he might bump to Kim Shin or Se Joo then fall in love again. I just wish that they could have given a preview of Mi Rae marrying Se Joo and Mi Rae marrying Kim Shin.
