On March 12, Shen Mo’s world began its countdown. Trapped in the mire of a broken family and the shadow of school bullying, he was an island on the verge of collapse, until a girl named Meng Niannian appeared. Like a blinding ray of light, she ruthlessly pierced the darkness, shielding him from every cruelty and granting him a gentle springtime illusion. Was she his salvation, a miracle, or the most absurd wish of a boy on the verge of death? When the diary opened, when the face in the painting blurred, and everyone began asking, “Who is Meng Niannian?” only then did he realize that this salvation he could never forget might have been nothing more than a solitary war raging inside him.
