Jae-sik (Jin Goo) is the owner of an event management company who poured his life’s savings into his work, only to be left drowning in debt. Following the sudden death of his employee Ji-young, Jae-sik finds himself the guardian of Ji-young’s 7-year-old daughter Eun-hye (Jung Seo-yeon), who is Deaf-Blind and has had no contact with anyone other than her mother. At first Jae-sik pretends to be Eun-hye’s father with the intent of claiming the refund of Ji-young’s tenancy deposit, but when he discovers that he can understand Eun-hye’s unique touch-based language, Jae-sik’s previously dull life takes on new colours as Eun-hye's world expands.
