The Suzuki family consists of the son, Koichi, his sister Fumi, and his parents Sachio and Yuko. Koichi is a hikikomori or stay-at-home shut-in. One day, he decides to take his own life and leaves his family in confusion. His mother, Yuko, upon discovering his body, goes unconscious because of the shock. She regains consciousness after 49 days but devoid of any memory of Koichi’s death. Fumi then tells her that Koichi has stopped being a hikikomori and now works in Argentina."
