Haruka was drinking with a female friend at an izakaya bar without her husband's attention. However, because she was drunk, she ended up getting involved with Shinji, a student who was drinking at the seat next to her. She didn't contact Shinji after that because she felt awkward, but she suddenly ran into him on the street and she ended up having a relationship with Shinji. Then, she received a duplicate key to her room from Shinji, and before she knew it, Haruka was looking forward to using her duplicate key and waiting for him to come home.
