Cen Ningyao's life is a trajectory filled with scars from congenital heart disease and successive separations. Her parents died young, and she and her grandmother depended on each other. The handkerchief embroidered with daisies was the salvation woven by her grandmother's frugal tenderness. But when she was fifteen years old, her grandmother died of a cerebral hemorrhage.

When the heart palpitations caused by overexertion pushed her into a coma, she clutched the daisy handkerchief and murmured, "I really want to hug grandma again." A red light suddenly appeared in A Mole's eyes, and in the distortion of time and space, she fell into an old time to make up for regrets. And the secret of the red mole cat, the forgotten fragments of childhood...
