It is a path on the back side of Duksu Gung, a palace from the 15C, located right in front of Seoul City Hall. If you want to test your love between you and your partner, take a walk together in this street. More than long ago before my grandma's generation, people believed that couples that walk through this beautiful stone-wall path will break up eventually. I have been there with 2 or 3 boyfriends, which I all broke up with. Was it really the curse that made us break up? Maybe, maybe not.
