The parasol trees along Wutong Lane blanket the walls with leaves year after year. The scent of gardenias drifts through the height of summer, just like the things a boy cannot bring himself to say.
While on cleaning duty after transferring schools, Lin Zhiyu wanders into the equipment room and finds Shen Ciyan playing the piano. One compliment spoken without thinking sets off a mutual secret crush.
She is a transfer student trapped by anxiety. He is a physics genius tormented by a personality disorder. A problem book filled with notes, several letters never sent, and a bowl of crushed grape ice jelly bind their mutual secret crush together.
Their illnesses become an impassable divide. He goes to Switzerland for treatment, and a note marked "Agreement Void" sends her to New Zealand, carrying a misunderstanding with her.
It is not until five years later, at a gravestone carved with grapes in a Swiss cemetery, that all the buried affection is revealed.
This is not a story with a happy ending, only a longing that crosses the boundary of life and death, and regrets left behind by time.
Dedicated to the youth of those who loved but could not be together.
