Su Nian, a girl with a heart disease, and Gu Chi, a lonely transfer student, became roommates, and the two unhappy people got close to each other. After agreeing to be admitted to the same university, Su Nian's condition worsened and she underwent surgery without telling Gu Chi. The operation failed. During the college entrance examination, Gu Chi went crazy and wrote her name all over the test paper. Later, he went to visit her in the cemetery every spring equinox, took the exam for the literature department she wanted to study, and finished writing their story for her.
