Recommend me some Makjang drama

Marriage Contract and My Love Eun Dong, maybe? A lot of people like them because they manage to make makjang tropes feel fresh and organic.

Beyond the Clouds, then. I think it's more up your alley.

Passionate Love (secrets & lies kind of makjang - and the romance will not go as you probably would think)

Wang Family (big family, big headaches, stupid decisions kind of makjang)

I Summon You, Gold (also secrets & lies, twins drama, complicated romances)

Baker King, Kim Tak Goo (shoter drama but by no means shorter levels of makjang)

My Heart Twinkle Twinkle (crazy villain type of makjang)

Triangle (it's more melo than makjang, but it gets convoluted enough to be fairly similar)

Glamorous Temptation and I have a lover.

Can You Hear My Heart
One Well-Raised Daughter
Bride of the Century
Wild Romance
Yong Pal

When I hear Makjang the first thing that comes in my mind is Innocent Man/Nice Guy

I know I'm late to the party, but if you're still looking for makjang dramas I have a few suggestions if you're willing to take them :3.

 Jang Bori Is Here is an ABSOLUTE must (it's my favorite drama ever). Some makjang elements: amnesia, reversed roles, a sisterly rivalry, a WICKED crazy villain (personally, Lee Yoo Ri pulls off this role the best out of all the makjang dramas I've seen), and a lost child.

Golden Rainbow is also another one I liked, although it's not as makjang as Jang about Is Here, they both have similar/about the same makjang elements.

Finally, I love Five Fingers (mostly because it's piano-based and I'm a pianist myself lol). Some makjang elements: birth secrets, a conniving mother, a brotherly rivalry (not unlike Jang Bori), family favoritism, and revenge (the whole drama is based on Ji Ho'a revenge anyways, lol).

Happy watching and feel free to let me know if you like any of those three or not!
