Yurikawa is a medical student. During one assignment given by her lecturer to research the diversity of vegetation near her home, she accidentally encountered the fate of her life. That day, while fumbling with her research on a small hill, Yurikawa accidentally bumped into a tall man. It turned out that he was a senior from the upper class, and after a brief conversation, they discovered that he was also working on a similar project. Feeling a strong connection and wanting to exchange more knowledge about the topic, they decided to go to a nearby inn to discuss more comfortably. However, not long into their discussion, Yurikawa's beauty and charm made it difficult for the guy to hold back. He began to explore every part of her body, and of course, she appeared to be very compliant, showing no resistance at all. This indicates that she also had feelings for him.
