Ji Ran, a seventeen-year-old freshman in high school, was caught off guard by a beam of gentle moonlight belonging to adults in the noisy corridor.
Zhang Lu is the math teacher from the class next to Class 3. He is cold and gentle, with gentle eyebrows and eyes. This is a secret that the young man cannot hide.
He originally thought that this heartbeat would only stop between the podium, separated by the status of teacher and student, separated by the insurmountable age gap, and forever buried deep in his heart.
But fate happened to intersect again and again.
The desperate rescue in the basketball game, the long-lasting dependence when alone, the restrained and forbearing confession by the lake at dusk, and the numerous obstacles brought by worldly friendships.
The young man's love is passionate and reckless, carefully hidden in every pursuit of his eyes.
She was rational and self-possessed, and gave in step by step, but in the end, she was unknowingly disrupted by her sincere young heart.
The mountains and seas are so close, but teachers and students are different.
The heartbeat of a seventeen-year-old is a secret hidden in the evening breeze and moonlight that one never dares to tell.
Purpose: To depict the secret love of a young boy, and to interpret the growth between reason and heartbeat.
