What is the show about?
The story centers on Yeo Eui Ju, an ordinary high school student who prefers to stay in the background. She does not stand out in school and lives a quiet, simple life. But at night, she becomes someone else. She secretly writes bold BL romance stories and uploads them online. Even though she is passionate about writing, her stories barely receive any attention. Eui Ju is very observant and understands people well, but she struggles when it comes to her own love life. She has no real experience with romance. Her life begins to shift when four new teachers arrive at her school.
Ga U Su is a calm and highly intelligent math teacher from a well-known family of mathematicians. He once planned to study abroad but gave it up after an incident that nearly cost him his vision. No Da Ju is a cheerful and playful Japanese teacher from a wealthy background. He can speak several languages and has been close to U Su for a long time, even though they often argue. Jung Gi Jeon is a former luge athlete who had to retire because of an injury. Now a sports teacher, he notices Eui Ju’s natural talent for running and encourages her. Yun Dong Ju is gentle and respectful, always kind to his students and careful with his words.
As these four teachers become part of her daily life, they start to inspire her writing. At the same time, her real life begins to feel just as complicated and unpredictable as the stories she creates.
