( CHAESOO ) it did not even start with a love letter, but it might as well have.

Lisa Manoban, a foreign exchange student in South Korea, finds her world, everything she knows and believes tested to their limits, along with her sanity when one day she enters a hidden room on her campus and walks into an American high school in 1964. There, she meets a student called Jennie Kim who makes Lisa's life even more difficult. Is Lisa crazy or has she really found a door that allows her to travel through time and across the world?
