Shinji visits his father Ryuichi, who runs a company in Tokyo and lives there alone for work. Surprised by how neatly kept his room is, Shinji watches as Ryuichi invites Hikari, a woman he entertains for business, to the house. She skillfully prepares a meal, and seeing this, Shinji begins to suspect their relationship. Unable to celebrate Ryuichi's birthday and feeling lonely, Hikari is touched by Shinji's kindness. She whispers, "Hold me," and surrenders her body to him.
