Ji Nian received an anonymous letter,
Between the lines is a girl's love for a boy.
One day, the boy in the letter appeared, looking at her with eyes filled with hatred but full of nostalgia.
She couldn't understand it, but she got deeper and deeper step by step, unable to see her way back among the vast stars in his eyes.
Intention: If you don't see the way you came, don't ask about the way back.
