Dear My Sister

Han Bok-hee is a girl who studies very hard and works at a brewery. When she was five years old, her parents divorced and Bok-hee went to live with her mother. Her father died in a coal mine accident. Her mother Yoon Jung-ae got remarried to Song Byung-man, the owner of Dukchun, a brewery company. Although Bok-hee addresses her mother as "aunt" in public, people later learn that Bok-hee is Jung-ae's daughter. As a result, her stepbrother Bok-nam is sent to an orphanage, and Bok-hee leaves for Seoul. Kang Joon-mo worked as a stuntman, but due to injury had to quit his job. He comes to Dukchun to work as a temporary teacher. Joon-mo meets Bok-hee for the first time when she peers through the window of a classroom in which he's teaching. Joon-mo sees the passion in Bok-hee's eyes and becomes her mentor.
