The supervisor at work is an intimidating asshole, and Kaori is the senior colleague who always comes to my rescue when he berates me. Then I catch the two of them having sex in the executive office. Thinking she is being sexually harassed, I record them as evidence—but things are not quite what they seem. Later, after I make another mistake and come in on my day off, Kaori arrives to help. The air conditioner is broken, the office is unbearably hot, and her sweat-soaked body looks sexier than ever.
