Air City

Runway Two is closed due to birds and operation headquarters try to devise a measure before the holidays. While Ji Sung and Myung Woo wait for a meeting, Do Kyung walks in on them and leaves, embittered. Later, Do Kyung finds Myung Woo waiting for the bus with luggage, and offers that she stay at her place. On the same night, Do Kyung follows the North Korean research team's advice and draws a big bird on the runway. Ji Sung offers help, but Do Kyung declines and sends him to Myung Woo.
