[Signed] With 279 days left until the college entrance exams, a "color-blind genius" named Shen Jibai joins Class One, Senior Year, at Nancheng Experimental High School.
He lends Lin Xian a pencil that glows, and with it, a quiet kind of salvation.
Lin Xian is a campus photography blogger with 300,000 followers on Weibo. Through her lens, she can distinguish millions of shades of blue, but she can't make sense of the gray areas in her remarried family after her mother's early death. Shen Jibai is a national training-camp student in the informatics competition, admitted to university through a special recommendation. He sees only black, white, and gray, yet in her photographs, he sees blue for the first time.
On a rainy night during a power outage, they sit side by side on the glass roof of the library. A glow stick lights up the stars, and their two universes, too.
As rumors, misunderstandings, and their fathers' hidden pasts close in, she writes about her unrequited love on a private Weibo account, while he hides his confession in Morse code at the end of a pencil. She travels to a snow mountain 4,500 meters above sea level in search of answers. He shields her from every storm, saying only:
"Don't be afraid. The wind carries the stars to you, and I'll spend the rest of my life carrying it to you."
From senior year of high school to senior year of college, from Nancheng to Yubeng Village, and onward to MIT and the starry corridors of National Geographic...
Their love heals them both as they grow together, becoming light in the cracks of their lives.
When the countdown reaches zero, the pencil's star finally lands at their fingertips, and the Milky Way bears witness:
"You are the end of every blue light I follow, and the only coordinate I'll ever need."
