I Came to Clean

Woo-Yeon (27) has been dedicated to the company for 7 years, but is passed over for promotion because he is a high school graduate. He postpones cleaning with the excuse of working overtime, and his one-room apartment becomes a garbage dump. Woo-Yeon, who has become lethargic due to the fatigue and stress of the past, cannot get up from the garbage dump. Until a strange woman, Ha-Ra (28), comes and cleans the garbage dump... What is her true identity?
