University student Yayoi emits strong pheromones, recently gaining attention after being approached at a park. Rumors claim she works at a hostess club, but surprisingly, she's actually a female college student majoring in mechanical engineering at the Faculty of Engineering. Her use of CAD and software in studies has sparked skepticism. She appears proud and strong-willed. Belonging to a basketball circle at university, the contrast between her appearance and reality has drawn significant interest. Her ideal man resembles Miyagi from a popular basketball manga, and she reveals her past breakup was due to infidelity. Highly self-aware and academically gifted with a high deviation score, she now seeks a new, even if spoiled, boyfriend with perfect physical compatibility. To find him, she's hosting a "Matching Dick Party"! Using all five senses, she'll select her destined penis from six candidates, evaluating factors like pubic odor, testicle texture, pubic hair volume, shaft hardness, and pre-ejaculate taste. Anticipation builds for this event where she'll use her vagina to discover the most compatible cock.
