Yes, take it very literally.

I am not a die hard fan of Korean love flicks because almost all of them are so childish. But of boredom, I decided to borrow a compilation of K-romantic comedies from my boyfriend's sister. Honestly, I quite enjoyed most of them, hahaha, talk about guilty pleasures.

As much as its title implies, this flick is about a girl who needs to serve an arrogant, rich, and good-looking young man, for a hundred days. And yes, you guessed it: they fall in love in the end. It wasn't that sucky, I guess. Koreans are the epitome of romantic comedies, indeed. :)

PS:
It's funny how the translations of Korean titles turn out in English. It's too literal, it sucks sometimes. :P
