After getting divorced overseas, a novelist Chang-seok returns to Korea and readies to publish a novel based on his own life experience. He then meets the aimless Mi-young at a cafe located inside a bustling subway station in Euljiro who recollects her meeting with him and their past together. Chang-seok also meets his editor, Yoo-jin, who shares a leftover cigarette with him and thinks about her past. Next, he accidentally runs into a photographer Sung-ha who’s taking care of his ailing wife. Last, Chang-seok shares a conversation with bartender Joo-eun, who tries to remember her memories from her patrons lost after a car accident.

Upon meeting each others, they explore slightly different themes, but each is connected with a shared feeling of loss and insecurity as each character struggles to remain sane in a society that evokes feelings of existential dread. This marks Chang-seok and changes his feelings and mind, also making him choose to begin writing yet another new story.
