Suddenly returned to before he was replaced by his savior.
Mu Qizai, who only realized that this was a fantasy world when the "end of the world" came, was obviously not a protagonist. His life was saved by the good man Xie Bingzhu when the crisis came.
Xie Bingzhu was just a high school classmate whom Mu Qizai knew nothing about except his name. Xie Bingzhu usually had a cold personality and the two of them had basically no interaction.
However, in the darkness where the world's people are complicated and intertwined, he witnessed the life and death of this unknown boy. He only heard a very soft sigh, and then the world fell into silence.
He was a random and lucky passer-by, while Xie Bingzhu was a kind-hearted and brave hero. The young man he didn't even get to know died trying to save him.
He just began to understand the reality and illusion of this world, began to understand part of his savior, and learned that he was seriously ill at the time. He lived for ten years with the life he had been saved, and finally died in the chaos.
But he suddenly returned to before everything began, to the three years before he was saved by his savior, and to his high school days.
Mu Qizai: Woohoo, savior.
I want to be good friends with him.
Intention: Someone can see your kindness and gentleness, so they come close to your world to offer salvation.
