Sumire, who started dating her childhood friend, suddenly faces her father's company bankruptcy. Moreover, the house was just renovated, leaving a huge loan. Sumire's father asks her boyfriend's father, who had been looking at Sumire with lewd eyes, for money in exchange for her services. Not stopping at the boyfriend's father, the father plans to start an illegal brothel with neighborhood old men as clients. Innocent and pure Sumire gradually awakens to the pleasure of service using lubricants and other tools, falling into debauchery.

Having actually watched this work, it follows the synopsis with a theme of falling into pleasure, depicting the process of descent in detail. Particularly, the transition from initial innocence to gradually awakening to pleasure is skillfully expressed using props like lubricants, and the final scene where she greedily seeks pleasure on her own is striking. Although the storyline might seem dark, the overall tone, enhanced by Kurimoto's performance, gives a rather bright impression. The character's growth and changes are naturally portrayed, full of elements that draw viewers in.

Overall, the psychological depiction and physical changes during the descent feel realistic, adding depth to the work. Kurimoto's acting shines, balancing the dark theme with a bright presentation, making it a compelling watch.
