Queen of No Marriage (2009)

The Korean Version is essentially based on the Taiwanese one that came out in 2009. This one has a great cast, insane chemistry between the leads. Though Korean one is crisp and nice this one tends to get a bit narrative at times but nonetheless not the one to be missed if you liked the Korean one. Highly recommended.

This is another version of the story.

It's exactly the same drama but with different characters
-both are older women still single
-both do a one night-stand with the man that they first hate
-both men are dressed as Santa

Witch's Romance is a Korean remake of My Queen. The storyline is pretty similar but the mood and pacing differs. The Taiwanese My Queen has more over the top comedy as often seen in Taiwanese drama's and the Korean Witch's Romance seems to be more polished. Which of the two you'll like better will depend on taste.

it's also a office romance with an older woman and younger man. Their chemistry is amazing and there are lots of laughs once you get past the extreme silliness of the first two episodes.

Both have old women and younger man love and hate relationship

you get the office dynamics, old love vs a new love, successful career woman and nice chemistry between leads. PoH has more female friendships. Both have elements of over the top comedy at the beginning and end of the series

The fl and ml both have similar backstories in both dramas, and together they help one another to get over the others pain.

Both are noona romances between a successful and established career driven FL and the ML that is interning in her office.

In both story, there are older women- younger men relationship and also both women have male friends who love/loved them...

Older woman-younger man relationship. Lucas calls Wu Shuang "Da Jie" which means older sister.

Older woman, younger man relationship

Office girls had a similar feel. Some silliness, some cuteness and entertaining actors.

Noona romance with some forced cohabitation. There are lots of side characters in both that serve to move the story along, and aren’t just filler. Both male leads are very sweet and devoted while the ladies come off as incrediblely unsubtle at first.
