Yayoi, a 19-year-old woman from a seemingly loving middle-class family, lately has been haunted by the feeling that she has forgotten something important from her childhood. Her premonition grows stronger day by day. As if led by it, she decides to move in with her mysterious aunt, Yukino. For as long as Yayoi can remember, Yukino has lived alone in an old gloomy single-family home. When she is not working, she spends all day in her pajamas, clipping her nails and trimming her split ends. She sometimes wakes Yayoi at 2am to be her drinking companion and watches Friday the 13th over and over to comfort herself. A child study desk, old stuffed animals --- things Yukino wants to forget --- are piled up in her backyard like a graveyard of her memories.
