Nobody Knows

Detective Young Jin's every waking moment is consumed by a singular obsession: bringing the 'Stigmata' serial killer to justice, a monster who brutally took the life of her closest friend 19 years ago. The weight of that tragedy still clings to her, a constant reminder of her own powerlessness and lingering guilt. Her life is a solitary one, devoid of meaningful connections, a stark contrast to the vibrant world around her. Yet, her downstairs neighbor's son, Eun Ho, has managed to pierce the armor of her isolation. He's taken it upon himself to tend to her needs, performing small acts of kindness that have slowly begun to chip away at her defenses. One day, Eun Ho's quiet devotion will take an unexpected turn, setting in motion a chain of events that will forever alter the course of Young Jin's life.
