そんな家族なら捨てちゃえば？

Reitarou Shinoya is ignored by his wife and daughter and made to live alone in a small, dark room in his own home. He is allowed little beyond eating and sleeping there, while a line of cellophane tape in the hallway marks a boundary he must not cross. At first he treats these conditions as nothing more than unusual household rules. That view is shaken when a woman sees how he is living and asks whether it is domestic abuse. He then tries to restore his family despite the harsh tension inside the house.
