In the long history of history, there are always some stories that transcend life and death and become eternal legends.In the prosperous city of Beijing, on the street corner where convenience store No. 444 is located, there is such a poignant and persistent past hidden.

Caiqin, a ghost who has been dead for more than sixty years, is unwilling to be reincarnated. She will appear here on two specific days every year, quietly waiting for a young man named Ah Jin%..Her agreement with Ah Jin originated from a promise made on the battlefield.In that era of gunfire and uncertainty about life and death, Ah Jin made a promise to Caiqin that after returning from the battlefield, they would meet again at the location of convenience store No. 444.

Time flies, and seventy years have passed in the blink of an eye.Dongqing and Xiaoya, two young people who were moved by Caiqin's persistent waiting, decided to help her find clues about Ajin.However, the cruel reality told them that Ajin had died on the battlefield seventy years ago.Although Caiqin was unwilling to face such a result, she understood better that the fragility of life and the irresistibility of fate.

In order to fulfill Caiqin's long-cherished wish, Dongqing decided to reunite with Caiqin disguised as Ah Jin.At that familiar street corner, Dongqing cut Caiqin's hair short and took her to visit Peking City, which has become Beijing.Although Caiqin knew in her heart that the person in front of her was not Ah Jin, she was still immersed in this belated happiness.She knew that she had died long ago, and Ajin failed to return as promised.But this obsession made her decide not to just wait after learning the truth.

The next day, when dawn first appeared, Caiqin left quietly.She did not choose to stay in the human world, nor did she choose to be reincarnated.She wants to find her lover, no matter how far or how long it takes.This persistent love transcends life and death and becomes her eternal belief.
