Ambitious office worker Sakura Yuino has an unusual fetish—she loves the smell of a man. When she gets transferred to a different department, her new boss turns out to be the handsome Tatsuki Kiritani. He is popular with women, but seems disinterested in them to the point of even avoiding eye contact. However, it does not take long for the straightforward Yuino to figure out Kiritani's reason: he is overly sensitive to women and often has to deal with surprise erections.

Seeing how Yuino is attracted to Kiritani's masculine smell, she offers him a deal. Kiritani is to spend more time close to her so she can easily enjoy his scent and Yuino will assist him with overcoming his weakness in return. As both their situations are of sexual nature, it is only a matter of time before their relationship turns intimate. But thanks to all the office hours spent together and their after-work activities, the pair may just help each other find more than simple fulfillments of desire.
