Sungkyunkwan Scandal (2010)

Both are stories about a girl pretending to be a boy in an all boy's school. There is a lot of eye candy in the show too.

Both of these dramas involve the main concept of a girl dressing as a boy in order to enter a school however, both for very different reasons. 'Sungkyunkwan Scandal' is set in the late Joseon era whereas To The Beautiful You is a modern drama (based on the Japanese Manga, 'Hana Kimi'). Both are very enthralling.

if you like this drama To The Beautiful You is the modern version .

Crossdressing girl with three other hot guys! Who could ask for more!

both have the female lead take her brother's place and name, by dressing up as a boy

in both dramas, the main girl-lead passes the test to work in the palace. The male-leads both hate the girl-leads but fall in love with them slowly.
both have really good stories and lovely music.^^

=> a woman uses her brother's identity and pretends to be him to enter an all male group/institution.
=> the main group consists of 3 guys and 1 girl pretending to be a man
=> the main guy and the second guy are both in love with the main girl
=> the third guy is very cute and has a cute crush on the main girl
=> the second guy is the first to know of the main girl's identity

Both have a girl dressed as a guy to go to a boys school. In both the guys around the girl start to protect and fall in love.

Both deal with cross-dressing themes. My Bratty Princess, w/Jang Na ra and Alec Su, is set at the imperial court and deal with a girl of noble house who dresses up as a sort of a street robin hood and thus meets the emperor and a prince..
An unlikely friendship develops between them.

They have the same concept of "girl-pretends-to-be-a-boy".

In both dramas, the girl acts or "becomes" a man.
In both dramas are historical
In both dramas, the girl acts like a man because of their brother

both deal with women cross dressing to see justice realized, sungkyunkwan scandal takes the cross dressing much farther though.

There are a lot of similarities like, the main female lead is poor and helps people in malpractice. The main male lead is the one who arranged there entering into the school. The school is an all boys school so she has to dress up as a boy. The friends are now made up of 4 with the exact same personalities. It should be the chinese remake

Both saeguk, both with Micky/Park Yoochun in the leads, in both he is a known, rich person

Even though both dramas are made in completely different setting and style they have a very similar romantic plot. Not only the story is the same - poor girl dresses as a boy for the work/study opportunity that will allow her to support her family where she gets very close with the rich ML and they fall in love, both love stories give a similar feeling, of angst and back and forth between the leads while they go through an emotional roller coaster while exploring somewhat breifly homosexuality.
They even have lots of similar scenes and plot devices.
The bromance between the rest of the gang os also cute in both dramas.
