This is 50-episode long, and 38 episodes were shown so far.  I've been watching and can't believe I'm still following it.  I have never watched such a long drama series.  The story is not a flashy one.  It is a family drama, showing ups and downs, dark and bright sides of a multi-generational, multi-family household.
