The story centers around a young man who inherits his grandfather's plastic model shop after the older man falls ill. He's aided by Risa, a regular customer and busty plastic model enthusiast, who becomes a reliable part-timer. Together, they reopen the shop. One day, the protagonist discovers a solvent his grandfather created. After a work shift, while chatting with Risa, she begins to change without protection, and the protagonist accidentally spills the solvent on her. This causes a dramatic shift in Risa's demeanor, making her sexier and leading her to plead with him to "calm me down." The anime explores the unexpected consequences of the solvent and the evolving relationship between the protagonist and Risa.
