Sumire, who can work but has an overbearing personality, was always angry with her subordinate Sakurai. Sakurai decides to call delivery health to relieve stress. Sumire came to my house when I was waiting for Deriheru using a mysterious shop called "Acquaintance Deriheru" where your acquaintance comes. At first she thought she was some kind of surprise, but she turned into an obnoxious slut while saying dirty words. The next day, when she confirms with Sumire, it seems that she has no memory of Deriheru.
