Synopsis

This work portrays a world where the population has drastically declined due to the spread of a virus, and as a measure to extend life, only the upper class is allowed to possess “it,” an identical looking version of themselves.

Shinji (played by Iura Arata), who was raised in a wealthy family, had a daughter with his wife and seemed to have built the kind of ideal family that anyone would envy. However, he is suffering from a life-threatening illness and is undergoing treatment at a certain hospital. As Shinji prepared for surgery, Mahoro (Mizuhara Kiko) a clinical psychologist, was constantly monitoring his mental state.
However, Shinji was plagued by anxiety, unable to sleep, and had no appetite day after day. Mahoro tells him, “Talking about the things you’ve been bottling up can lead to better results in the surgery,” prompting him to revisit memories from his past.
As his memories resurfaced, Shinji became even more overwhelmed with anxiety and begged Mahoro to let him meet the being known as “it.” “It” refers to an identical version of oneself, a double that was provided to people suffering from illness. Shinji meets “it,” who looks exactly like him but has a different inner nature—pure and intellectual. Fascinated by this, Shinji becomes increasingly absorbed in “it.”
