K-POP - A Audição Final (2012)

both have a female main character who dresses as a man.
both are set in the world of idol music.

The girl who looks like a boy, and a guy who thinks he's in love with male :D

Both have a focus on music and are aimed at young adults.

Both dramas are about music industry. In both you'll be able to see a group of 'kids' trying their best to debut, true friendships and loyality, love between an idol and a non-idol, achieving dreams, dating issues and the most important: a music company lying fans in order to cover their idols and keep their company up.

both dramas are about celebrity life and both the male leads are conceited. ;)

both cross dress stories. similar characters. both are very light, and fluffy, more suitable for a younger audience

its both about girls going as boys even though in k pop she does it because she wants to be famous and its her dreams but in ikemen its for her brother's dream.. its somehow has the same feeling its both

Both talk about the life of a kpop group.

A robot or another guy: a relationship seems impossible, so it is easy to open up. But what is this feeling towards this guy or robot?
In both cases we see a slow growing of fondness and friendship, that is impossible to result in a boyfriend/girlfriend-relationship. At least it would be, wouldn't the guy or robot be posing as such while really being a girl.
Also again: soundtrack similarities. It really is clever, to produce a few good pieces to put them into multiple dramas!
Same goes for the Liar and his lover - just confusing, that in both dramas the same song is "composed" by the characters, otherwise it could be called "same universe".

They both are centred around a bunch of teens training to be idols with a bit of romance involve too

in both dramas there is a girl who dress up as a boy. to make their dreams come true!

Music, love, friendship, desire of achieving dreams, that's what this drama and movie have in common. You'll see a girl wanting to make her debut with some boys, a love story between a famous guy and a 'soon to be famous' girl, the ex-girfriend trying to get her guy back and also, the end in both drama and movies seems to be rushed.

The same kind of boy band meet girl idea. The main male lead has a love/hate relationship with the main female lead.

both have girl pretending to be a guy.

Both are about dreams of being an idol, and a person who sabotages their 'honest' efforts :)
