I have gotten this drama since last year but didn't watch it because of its wierd publicity poster. Without having any dramas to watch, I started on this last week and finished watching in a week! It's awesome! The drama is Rooftop Prince (북탑방왕세자).
It talks about the crown prince Lee Gak from Joseon who travelled 300 years into the future and met Park Ha, the reincarnation of his "missed" love. In this journey, he discovered the evil character of his Joseon crown princess and later fell in love with Park Ha, the reincarnation of the crown princess' sister.
The ending was heart-wrenching. The writer has written a good story with good story features linking the Joseon and present day storyline. The only part I don't like is that they didn't explain the part when Park Ha went to the library to read up on the history about Lee Gak.
Because of the show, I like Park Yoo Chun now. Will start on his most recent drama - Missing You.
In one of the episode, Park Ha demostrated how to eat instant noodles with the four characters from Joseon. Here's the noodles:
