Hi, i'm searching for a (i think its korean) drama where the father doesn't really know his family and, when he die, his soul enters in his sons body, so he uses that opportunity to know and help his family.

Anyone knows the name of the drama?

Thanks.

Kind of sounds like the Korean movie The Dude In Me :  ML doesn't know his family but he gets into an accident and enters a younger mans body and uses that opportunity to know and help his family (he doesn't die though and the body he swaps into isn't his son)

Also kind of sounds like the Japanese drama 49? I have yet to watch this but the plot sounds similar.
