Transfer student Su Wan always reads beneath the old locust tree in the library's farthest corner. It's her secret hideaway from the crowd. Then one day, Lu Yu, captain of the school basketball team, crashes into her clear skies with a basketball in his arms. He plops down across from her without a second thought, his sweat-soaked jersey smudging her notebook and disrupting the "invisible" presence she's been trying to maintain in her new surroundings.
One is a shy girl forced by her mother to attend an elite high school, shackled by the demand that she "must get into a university in the south." The other is a sunny boy living under the halo of a "genius athlete," yet pushed by his father toward a professional career. They're like parallel lines that should never meet, yet they keep colliding between shelves stacked with old books. She catches him removing his bandages in the equipment room; he discovers the stunning illustrations hidden in her notebook. Her eyes redden as she helps him with math; he takes her away from her oppressive home to watch a magnificent sunset.
When Su Wan's mother suddenly cuts off her art lessons, and an old knee injury threatens Lu Yu's final league, the two who are used to shutting themselves away finally learn to trust each other with their backs. A soft glow spills between the library's pages, illuminating the struggles they've hidden in the shadows and teaching them, in the summer of their seventeenth year, that growing up isn't a solitary journey. It means finding someone who sees through your disguise and is still willing to walk beside you, one step at a time.
