Waahh! I am now addicted to a korean drama entitled Secret Garden. :) Yee.. I love HYUN-BIN a lot (Playing the role of the lead actor) and also HA JI-WON (playing the role of the lead actress) :D
The drama tells the story of Kim Joo Won (Hyun Bin), a seemingly perfect man who hides an arrogant and eccentric side, and Gil Ra Im (Ha Ji Won), a stuntwoman whose beauty and body are the object of envy amongst top actresses. One day they went deep into the mountains and entered a strange house, where a strange grandmother offered them chocolate to eat. The next day, they found themselves in the other’s body.
