Miharu is a 26-year-old office worker. She has an older boyfriend, a banker, and is thinking about marriage, but she doesn't have high expectations for her sex life with him. When she started going to a fetish bar by herself and was being harassed by a persistent customer, a young staff member came to her rescue. That person was An. Although An is only 20 years old, she handled the customer well without causing any trouble, and the two have become good friends ever since. One night, while Miharu was drinking until closing time, An asked her if she wanted to continue drinking at her house, and Miharu immediately agreed.
