Yeo Eui Ju an ordinary high school student who is average in every way and tries to keep a low profile at school. But at night, she secretly becomes a writer, posting daring adults-only BL novels online. Despite her enthusiasm, her work barely gets any views. Though highly observant and empathetic, she has always been hopeless when it comes to real-life romance. However, her life as a writer takes an unexpected turn when four handsome new teachers arrive at her school. Among them is Ga U Su, a cold and brilliant math prodigy from a family of renowned mathematicians, who gave up studying abroad after a life-changing incident nearly cost him his vision. No Da Ju, a playful and mischievous Japanese teacher born to a wealthy family, is a gifted polyglot fluent in multiple languages and U Su’s longtime friend, despite their constant squabbling. Jung Gi Jeon, a former luge athlete forced to retire due to injury, is now a warm but clumsy sports teacher who is popular among students and sees Eui Ju as his next prodigy, recognizing her exceptional talent in running. Lastly, Yun Dong Ju is a warm-hearted and modest Korean teacher who is respectful and soft-spoken, treats his students with respect, always uses honorifics, and never loses his temper. As these four charming new teachers arrive at her school, they become her unexpected muses. Their presence turns both her everyday life and her writing upside down.
