Plot
"Please visit my house"

A Japanese-style wooden house stands alone at the end of a new work with unnamed wild flowers in a deserted countryside. The beautiful house, which sounds like a piano in the daytime, however, begins to emit a gloomy atmosphere when darkness falls. Two beautiful sisters, neither an adult nor a child, live in this house with unusual energy. The day Sumi and Su-yeon live with their beautiful but nervous stepmother. The family's ghost story begins.
On the day when sisters Su-yeon and Su-mi returned from a long medical treatment in Seoul, stepmother Eun-joo welcomed the children, but the sisters seemed reluctant to her. From the first day we moved in together, there was a strange energy in the house and the family was welcomed or haunted by nightmares. Su-mi tries to take care of her father, Moo-hyun, and her sister, Soo-yeon, who looks exactly like her birth mother, is always scared. Eun-joo, who is sensitive, fights with the two sisters repeatedly, and her father, Moo-hyun, just watches their discord. Eun-joo shows signs of emotional anxiety, driving the house into a state of fear, and Sumi, who is struggling to protect her younger brother, confronts it, and strange things begin to happen one after another in the house.
