Im Na-mi (Yoo Ho-jeong), a wealthy housewife and mother, does her daily routine. While things look perfect on the outside (wonderful home, generous husband, beautiful daughter), she is depressed about her life. When she washes her face, she sees wrinkles on her skin. When she asks her husband to visit her mother at the hospital, he replies by giving her money to buy luxury bags, and her daughter expresses similar indifference and annoyance. Na-mi eats breakfast alone every morning while her husband and daughter head to work and school, respectively. She looks outside and notices a group of high school girls who are walking and laughing.
