When Shen Xing, a top-student girl, lowered her head to write under the light of evening self-study, she never thought that her deskmate who always liked to rub her arm with an eraser would hold her hand one day in the future and travel through her youth.
An invisible boundary is drawn on the desks of Qinghe Middle School. On one side is Shen Xing's handwriting as cold as moonlight, and on the other side is Lu Chi's casual and free graffiti. They were like two straight lines that were not supposed to intersect, but quietly approached in an accident. Lu Chi began to imitate Shen Xing's notes, and Shen Xing would occasionally hide a smile at the corner of his mouth for him. But when the teacher noticed their subtle changes and forcibly moved the two away from each other, the invisible thread was torn apart, leaving empty seats and oppressive silence.
Lu Chi stopped skipping classes, and Shen Xing learned to look up at the sky. They exchanged exercise books in the corner of the library and ran around the playground memorizing words, as if they could overcome all high walls by walking side by side. But the price is loneliness, misunderstanding, and doubts and denials from the adult world. Lu Chi's friends said he was "love-brained", and Shen Xing's mother warned her "don't ruin your future." They stand between reality and dreams, responding to the world's prejudices with every effort.
On the day when the college entrance examination results were released, the sun penetrated the glass of the classroom and shone on the two admission notices. They can finally walk together openly. But when true freedom is in front of you, can love still remain the same?
When the future comes, how should humans choose?
