Ha-seon is an estate cleaner. He possesses a special power to read 'memories and emotions' from the traces left behind by the deceased. He works at an estate cleaning office named 'Yuwa'—a place that picks up and delivers the innermost thoughts of the deceased that even their surviving families do not know. One day, Ha-seon saves a woman named So-hee, who was attempting to take her own life. This encounter leads her to join 'Yuwa' as an estate cleaner as well.
