A month’s vacation suddenly given along with the summer vacation due to the renovation of the building where I work.
Akito Natsuki, who has no money and nothing to do, decides to spend a relaxing time in her hometown.
What she was waiting for was Kaiyuri, who once had her feelings for her, and Sayoko, who was kind to her like her mother.
As usual, she should hide her feelings and play her brother-in-law, but by accident she talks about her true intentions.
The relationship that had stopped begins to move little by little, and eventually becomes deeply intertwined.
