Shoko is a female investigator who always likes to work alone and doesn't think carefully. During the operation to capture the mob boss Kiyoshi, she didn't anticipate everything and ended up shooting and injuring several people, causing a strong condemnation from the media. Her superiors, in order to appease the press, released Kiyoshi and gave her a 15-day disciplinary action. After the disciplinary period ended, Shoko continued to monitor their new hideout. This time, to prevent her impulsive actions, her superiors sent Sano to assist her and at the same time monitor her. In the middle of summer, deliberately making it difficult, her superiors didn't allow air conditioning, and the surveillance had no progress. Shoko gradually became less alert due to the heat. She took off her bra to cool down, not knowing that the sweat and the thin shirt had fully revealed her huge breasts to Sano. Although he wanted to, Sano didn't dare to do anything because Shoko is known to be strict. But when he woke up, he found Shoko kissing him, making him no longer restrain himself. They passionately engaged in a seven-day affair to forget about the scorching heat of this summer weather...
