Hi , recently I really Enjoy Family  K-Drama that has 50+ eps . 
I Watched Ojakgyo Family , Five Children , they become my Fav Drama &  very love them .
I would highly appreciate any good recommendations please. Thank you.
Ugly Alert --- one of best! 
Family's Honor  --- excellent!... Same writer as above
Smile, You  ---- ROFL .... very, very, funny!
East of Eden --- all about revenge, family ties and brotherhood! .... action melodrama, w/ background of changing Korean history from 1960's-1990's.... 

Reply 1988 --- I haven't seen it YET!.... but heard lots of praise from people w/ various tastes and MDLers I trust like it!
All About My Mom it was quite enjoyable to watch.
I also recommend  Smile, You the characters are likeable and the romance is adorable.
The Gentlemen of Wolgyesu Tailor Shop is currently airing, so far the story has been nice.
my favorite genre  XD  Ojakgyo Family is my all time favourite. Here is some familiar ones :
