Shining For One Thing

On the eve of her wedding, Lin Beixing is betrayed by her fiancé Zhan Yu. Heartbroken, she revisits an old phone and accidentally travels back to high school by deleting messages.

Back in the past, Lin Beixing learns that top student Zhang Wansen—who later falls from a water tower—blocked her “perfect life.” She decides to save him.

Using the phone again, she returns to senior year and tries to transfer into Zhang Wansen’s class, but he avoids her constant attempts to get close.

Lin Beixing pushes Zhang Wansen to tutor her while dealing with troublemaker Maizi. Meanwhile, Zhan Yu starts developing feelings for her due to her changes.

To keep Zhang Wansen safe, Lin Beixing tries to separate him from Gao Ge. She and Zhang confront Maizi, and their bond grows closer.

Zhan Yu pursues Lin Beixing and challenges Zhang Wansen to a basketball match. During the game, Lin senses Zhang may be the boy who saved her in childhood.
