Plot Summary

Five years ago, Hana’s family was shattered by a tragic car accident. Her mother has been in a coma ever since, her father walks with a limp, and her younger sister Luna suffered severe burns that left her wearing a mask. Hana has no physical injuries, but carries the heavy burden of survivor’s guilt and hasn't been to school since. Hana befriends Jun, a boy who is searching for answers about his mother’s mental collapse into silence. As Jun finds more similar cases, he begins to suspect that Hana's father – a psychotherapist – is somehow connected. One day, Hana’s father brings home a woman he says is their mother, awakened from her coma. Luna accepts her without question, but Hana is convinced that the woman is not her mother – her appearance is too different. Who is she, and why would she pretend to be their mother?
