Yuzuki, a rookie teacher, is thought of by those around her as a serious and capable woman, but on the other hand, she has been unlucky with the men she dates, constantly attracting losers because she is too soft-hearted. She has even experienced sexual harassment at work and worries that if things continue this way, a mistake might happen. Because she tends to over-devote herself, her spirit of service has made her exceptionally good at blowjobs, but she wanted to change herself... she wanted to shine as an active woman rather than a passive one... for that reason, she decided to appear in an AV.
