Asian dramas with underdog heroines?

I'm getting into Asian dramas lately. I like the romance genre, in particular with heroines who're sort of the underdog/have tough cirstances. For instance, Hana Yori Dango, where the heroine was really poor whereas the hero was filthy rich, or A Wolf's Tale, where the heroine was a country girl who just moved to the city whereas the hero was really popular/well-established in her high school. I tried Full House but had to quit somewhere in episode 2 (just didn't like the characters, especially the heroine). I really liked Autumn Tale (hero/heroine grew up together, were separated, and reunited--hero had a pretty good, easy life, heroine really had to struggle) and Coffee Prince (again, very wealthy, easygoing hero and a younger heroine who is working to provide for her family). Any recommendations? Korean/Japanese/Chinese/etc. are all fine...
