Neighborhood Watch

On a seemingly ordinary day, Min-Sook goes to her car to leave for work. There, she finds a blue bag hanging on the car's side mirror. Min-Sook looks inside the blue bag and food trash falls out. She's freaked out by that but thinks Soo-Ji is playing a joke. The next day, Soo-Ji finds a blue bag in front of her apartment door. Min-Sook's husband Hee-Chan, who is an unpopular novelist, views it as a misunderstanding or jealousy between his wife and Soo-Ji.
