A dream takes the heroine back to the time when the two first met. What she doesn't know is that the hero has returned with his memories to the same time and place she is in now. The day her grandmother dies, the whole world begins to collapse. The noisy sounds around her suddenly fall silent, and white starts to fill her vision.
Her own memories begin to surface little by little with Gu Yuqiu's appearance, bringing back all the proof of their love.
“Ah Gu” and “An'an” are names the two cannot speak of after they transmigrate.
But which timeline is this?
The ending has changed. Her beloved is with him, but Gu Yuqiu cannot survive either. He will never hear a girl softly calling “Ah Gu” at his side.
