At a prestigious institute in Seoul, academic pressure is at its highest. Seung-woo, a young math prodigy, is known as the "genius" of the classroom, but behind his brilliance lies a life of loneliness and high family standards. His mother, a former academic, expects him to follow in her footsteps and become an elite student. However, his self-esteem begins to falter when he crosses paths with Min-ji, a seemingly carefree student who doesn't adhere to the same rigid rules as he does.
When Seung-woo is forced to tutor Min-ji, he initially sees her as a burden, but soon discovers her unique perspective on life. She not only teaches him to relax, but also encourages him to explore his passion for music, a talent he had pushed aside. As their relationship strengthens, they both face the challenges posed by their families and the expectations of their friends.
In an unexpected twist, a family scandal puts their connection to the test, forcing Seung-woo to decide between meeting expectations or following his own path. With emotional moments and hilarious situations, the story blends comedy and drama to depict the journey of these young people towards self-definition and the pursuit of true happiness. It serves as a charming reminder that sometimes, true success is not measured in grades, but in the freedom to be oneself.
