The abnormality of the mother, Diane, is evident from the PV and key visuals. However, this development gradually became more apparent as the film was viewed as thrilling. This development was a thrill for Chloe's daughter as she moved from the mental confinement of the beginning to the physical confinement of the situation. I enjoyed the thrill when I started watching and the different thrill by the end of the film.

It was a story of love from a snarky daughter to her mother and love from the mother to her daughter. Since there were two perspectives, one from the mother and the other from the daughter, I wondered what kind of “twist” there would be, but it was not such a suspenseful story.
