Soup is not free.

Su-min runs an instant noodle shop in a lonesome street. She lives her life alone sometimes with solitude and sometimes even with a cold heart. However, Tae-woong helps her with the delivery in return for having stir-fried noodles at the shop for each meal and Yoo-jung, a new housemate, keeps making homemade food to share. On the month of the last payment of debt, Su-min realizes that homemade food's quite comforting.
