Jo Eun-kyung

Jung-woo is a part-timer at a bookstore. He has a crush on Seo-yeon who works with him. One day while preparing a book gift with her heart, Seo-yeon’s old lover appears in the bookstore.

Author Juyoung recalls the moment when he saw the dragon's tooth – the traces of war. His memory deepens, and he visits Nuri to find traces of his dead student. People beyond time, all those memories of love allow us to live despite the traces of frozen wounds.

Actors and film students Geum-joo and Dong-geun descend on Muju, the hometown of their classmate Min-ju. Their task is to create the "first memory" of the person the play--the memory that has been kept in the character's mind for the longest time, the memory that has become the character's unconscious.
