Su Ruan's high school life was originally a one-way track filled with formulas and incorrect question papers. It was not until the appearance of transfer student Lin Nanzhou that a ripple called "heartbeat" appeared.
She is the top student in her grade. She remembers the wrong questions in her notebook more neatly than her notes, and even her plan for answering questions is accurate to the minute. He is a transfer student with a cool temperament. He seems to be careless, but he can always compete with her on an equal footing. An unexpected group collaboration added content that was not knowledge points to the "Academic Master's Handbook" - Lin Nanzhou's profile while solving a problem, the warm milk tea handed to him, and the umbrellas they held together on a rainy day.
From the collision of ideas in the classroom to walking side by side after school, Su Ruan gradually discovered that the world of top academics not only includes scores, but also the gentleness hidden behind the formulas. When the pressure of entering a higher education and ignorance of emotions collide, the two agree to use their dreams as horses to sprint towards the same top university, letting the heartbeat of youth become the motivation for each other to move forward.
This is a "master's handbook" about growth and love. It records how two teenagers use knowledge to light up their youth, use companionship to warm their time, and write their youthful love into their own "sweet" chapter as they pursue their dreams.
