A brand-new delivery health experience begins here! A woman who looks just like someone you know shows up as a call girl. Yamada, a hopeless employee, is constantly scolded by his senior coworker Hibiki. Though she's beautiful and skilled at her job, her harsh attitude leaves him feeling miserable every day. Seeking stress relief, he calls a no-sex service, only to encounter the "Acquaintance Delivery Health" scenario—where, by sheer coincidence, the visiting girl turns out to be his own acquaintance. Half curious, he calls her again, and to his shock, it's actually his female superior, senior Hibiki, standing before him! Even when he questions her about it at work later, she appears to have no memory of the encounters. Again and again, he summons her as a call girl, using these secret rendezvous to relieve his daily stress in an increasingly bizarre and twisted situation.
