Mirabel works at a café, but her secret identity is that of an erotic novelist who writes to satisfy her own passions from a past life. She regularly writes at the local library, where her private indulgence is observing the librarian: a man with disheveled hair, thick bottle-lens glasses, a wrinkled shirt, and a conspicuously muscular physique. His appearance strikes every note of her personal tastes, and she decides to base her next character on him. Before she can finish, he discovers her notes. Instead of being repulsed, the librarian, whose name is Alan, recognizes the material as reference for a series he adores and excitedly declares himself her biggest fan.

As their interactions deepen, the two accidentally witness a couple engaging in a public outdoor scene, sharing a rush of excitement that brings them closer. Mirabel learns that behind Alan's messy exterior lies a stunningly handsome face. His good looks have caused him to develop such a severe complex that he remains a virgin, a fact he confesses to her. The story follows the evolving relationship between a sexually enthusiastic but inexperienced erotic novelist and a librarian whose handsome appearance has twisted his self-image, leading to a romantic and comedic entanglement filled with misunderstandings, physical humor, and mutual affection.
