guys i'm trying to find a korean drama that is broadcasted at local tv, i can't remember the name nor the channel that shows, i think is ntv7, or 8tv, or others i dunno.

the plot is like this. the guy had a young niece, and it seemed somehow the drama shows that in another timeline the young niece is in fact his girlfriend and that they're supposed to get married. the young niece kept on getting flashbacks of their different life and really like her uncle, which is the main character.

anybody know such drama?
