Shoko is a female investigator who always prefers to work alone and does not think carefully. During the arrest of the crime lord Kiyoshi, she did not anticipate the situation and ended up firing her weapon, injuring several individuals, which led to fierce condemnation from the media. Her superiors, wanting to appease the press, released Kiyoshi and disciplined her for 15 days. After her disciplinary period ended, Shoko returned to monitor their new base. This time, in order to prevent her impulsive actions, her superiors sent Sano to assist her and also to keep an eye on her. In the middle of summer, her superiors intentionally made it difficult by not allowing air conditioning, resulting in little progress in the surveillance. The heat gradually clouded Shoko's judgment. She removed her bra to cool off but was unaware that the sweat and her thin shirt fully revealed her large breasts to Sano. Although he really wanted to, Sano did not dare to do anything because Shoko was notoriously strict. But when you woke up, you discovered that Shoko was kissing you, making you lose all restraint. The two of you dove into each other, crazily making love for seven days to forget the heat of this summer weather...
