Marigold Mind Laundry by Chong-un Yun

Welcome to the Marigold Mind Laundry where we wash away the stains from your heart. After young Jieun accidentally misuses her powers, causing her beloved family to vanish, she lives a million restless lives in search of them. Overnight, in the village of Marigold on top of a hill, she conjures up her Mind Laundry, where she cleanses painful experiences from the heart, transferring them into stains on a T-shirt and turning them into dazzling red petals. We meet five wounded souls: a frustrated young filmmaker; a tortured social-media influencer; a distraught mother who has discovered her husband's other family; a young woman two-timed by her lover, and Yeonghui, a victim of bullying, who works as a delivery man to escape his pain in routine. After washing the pain and ironing their creases, Jieun discovers an astonishing revelation that will change her life.
