Yamazaki’s friends are bragging about jewelry and the nice things that they buy, so she begins to feel jealous. The solution? Whore yourself up for money… with middle-aged men in hotel rooms.
Yamazaki is hella cute, but her lack of acting in the sex scenes is kind of awkward. It could be argued that it fits the drama plot,
Also the 2 other girls, Yukina and Yua are AV actresses, but just extras in this movie.
