Mi-Na grew up there as an outcast and doesn't look fondly back at her childhood.

On her way home from her last day at work, she receives a phone call from people who lent money to her father and also the real estate agent back in Muju.

Meanwhile, Kang-Ho ( Bong Tae-Gyu ) returns to Muju to work as an elementary school teacher. He grew up there and had only one friend.
