Hi I've been looking for  good Makjang dramas. On the other recommendations I saw some people answered with shorter melodramas but please only respond with Makjangs. Makjangs are normally very dramatic 50+ episode dramas that are  family  based with a 99% chance of a switched at birth scenerio. I will list the ones I have watched, thank you in advance for the recs!

Jang Bo RI is Here

My Daughter Geum Sa Wol

Hide and Seek

My Son in Law's Women

Happy Home

Blow Breeze

The Promise

You Are The Best! 

Rosy Lovers

I Have a Lover

Glamorous Temptation

Hotel Kings (sort of Makjang?) 

Flower in Prison (Historical) 

Six Flying Dragons (Historical) 

Splendid Politics (Historical) 

Definitely New Tales of a Gisaeng


Others:

  1. Scandal: a wrongful and shocking incident - this is atypical length for makjang (36ep) but it has revenge, birth secrets, switched loves, evil fathers and all makjang goodness. This is definitely one of the most brilliant and Must watch drama in this category!
