Song Cha can see the last sight of the deceased by touching the relic. A girl from the art department fell to her death, and all clues point to the dark web "Wishing Pavilion" and a red vest that has been passed down for twenty years. The ghost in the mirror is asking for its life, approaching step by step. Song Cha's mother, who had been missing for many years, was actually the earliest registrant of the "Wishing Pavilion". She was in the mirror, waiting for him to come.
