hi, i want to know if any of you know this drama title.. the story about guy named Ki Yong/Lee Yong (something like that coz it's dubbed) who fall in love with a girl (she's older than him, if i'm not mistaken).. the last episode story is about he try to find the girl, the girl makes some hint like papers in the road that he needs to find which tell him where she is (if i'm not mistaken again)

i don't know if this drama is japan or korean, but this drama aired in my tv on 2005/2006.. i'm still in elementary school so i don't remember much about this drama. maybe any of you can help, thanks.
