Takeshi and Mizuki have been best friends since school. The two of us came to Tokyo to attend the same university. Takeshi is not popular with women, but Mizuki is popular with women, and sometimes brings her woman to her house. One day, Takeshi fell in love with an AV actress named "Natural Mizuki" and recommended it to Mizuki. When I woke up in the morning, Mizuki had become an AV actress Tennen Mizuki.
