Golden ginkgo leaves pave the way to the National Myeongde University in late autumn. The air is cool and clear, and there is silence and undercurrent between the light and shadow. Lin Qiu, an introverted but keen design student, is accustomed to capturing the whispers of the seasons with a paintbrush. An accident in which books were scattered caused her to meet the campus' "perfect legend" - Shen Yan, the senior student of the business school.
He has amber eyes and an impeccable smile, and his manners are as graceful as the warm autumn sun. A cool touch from the fingertips, an inadvertent professional instruction, quietly plucked Lin Qiu's heartstrings. However, the fleeting distant look under the perfect appearance, the sharp intuition about the "dummy" from her friend Charlene, and the heart-stoppingly accurate annotations he quietly left in her sketchbook are all like pebbles thrown into a calm lake, causing ripples.
Shen Yan is like a puzzle wrapped in sweet sugar coating. He approached casually and calmly rescued her. There was an elusive undercurrent beneath his gentleness. Lin Qiu was pulled by this complicated heartbeat and uneasiness, and swayed in the warmth brought by the sunny and cheerful senior Xu Lang. As the autumn atmosphere deepens and the maples turn red, a sudden academic crisis throws Lin Qiu into the center of the storm, accidentally tearing off a corner of Shen Yan's mask of gentleness - the means he uses to protect or control are cold and efficient, forming a cruel contrast with her throbbing heartbeat.
On the secluded paths covered with fallen leaves, in front of the cafe windows where condensation is condensing, and in the corners of the library with dappled light and shadow, an "Autumn Mystery" about truth and disguise, heartbeat and vigilance is quietly laid out. Can Lin Qiu see clearly the darkness behind Shen Yan's eyes among the cascading autumn colors and the complex maze of human nature?
