Yi An is lonely and tired of the world, and wants to find a confidant. Fortunately, he met Bai Jing and regarded her as a confidant. He was even willing to accompany this girl who wanted to die to death. However, on the originally agreed death date, Bai Jing disappeared and everything was put on hold.
After Bai Jing, Yi An met Tang Mu. Tang Mu's light-like existence illuminated Yi An, bringing him warmth and salvation.
As the two become closer and closer, Bai Jing appears again, hoping that Yi An will fulfill his death promise. Yi An is wavering between life and death, unable to choose between Bai Jing and Tang Mu, hesitant.
In the end, Bai Jing discovered that Yi An had escaped the haze of the past, found redemption and was no longer pessimistic and despairing. So I left a farewell letter and wanted to leave the world alone...
Intention: Life is as light as a feather. The meaning of each feather's existence is to meet another feather in this world.
