This is the only drama that i felt disgusted in the ending... really??? The writer messed it up real good.. omg! how could then end them together like wtf is happening???!! their mother and son!! even they insist that they are different person after all since they are in different dimension still i couldnt fathom why they did that way especially they make to remember the memories of the other self... gosh so messed up... they started good in the sci fi story line, they should stick in that way but they twisted it so much just to the main character end together..hell
