Mitsuba Uno, who attends university on a scholarship, is immersed in her studies and part-time work, and leads a life far removed from romance. One day, she meets Mitsutani Rei, an art major, and ends up cleaning his lab. Rei is a popular reader model who dresses in high-end brands and has a talent for drawing. Although Mitsuba knows that he lives in a different world than her, she begins to be attracted to him as they spend time together. However, Rei draws a line and says, "Don't get in here."
