Summary
Ji Yul-moo is a freshman university student who appears shy, nerdy, and completely absorbed in her studies. With thick glasses and oversized clothes, she gives off the impression of someone who’s never stepped outside the library. But beneath her quiet exterior lies a secret: she carries a green notebook filled with wild, perverted fantasies and stories that reveal a much more provocative side of her personality.
When Yulmoo joins a campus club, her life takes a dramatic turn. Surrounded by attractive and eccentric upperclassmen, she begins to explore her desires and challenge her own boundaries. The club becomes a chaotic playground of flirtation, awkward encounters, and emotional growth.
