Yi Xuan, a young man who is withdrawn and cold and accustomed to sealing his thoughts in solitude, has become an island in the class where no one can approach him due to his mother's constant travel and the shortcomings of his original family. Until Zhang Zexin, an enthusiastic and public art student, breaks into his world without warning.
Zhang Zexin used his blatant preference and unrequited companionship to break down Yi Xuan's closed heart little by little, accompany him through the late night collapse and the pain caused by his loved ones, and also led him to see the starry sky, the sunset and the tenderness of the world. From the deliberate approach during class, to the secret joy during duty hours, to the firm protection in rumors and rumors, and the persistence in desperate moments, two teenagers with very different personalities redeemed each other and ran in both directions during the hot time of their senior year in high school.
They walked side by side through the mud and confusion of youth, and finally followed the same starlight and entered the same university, letting their young heartbeat and companionship grow into a long and firm future under the starry track.
Intention: The meaning of running in both directions is to illuminate each other and become each other's light.
