● Hikari, an investigator who begins to stake out with a junior man in order to catch the mastermind behind the trafficking organization. A week of sweaty and abstinent days in a closed room with a broken air conditioner in midsummer. The two who exceed the limit break the thread of tension and cross the line. Two people who forget themselves and get stuffy even though they are on duty, hold in their mouths with Jupojupo, and violently entangle while mixing sweat and body fluids. Hikari who remembers the sex that she really feels though the relationship ends when the case is resolved.
