Synopsis

"Only at the very end of his life did Qi Ji realize that that girl had been sacrificing everything for him from the dark.
His entire life flashed across his mind like a movie.
He thought to himself, “If I get a second shot at life, I promise I’ll hold her hand the very first time I see her.”
It was as though God made a joke with him. Time reversed, and he returned to the point when the two of them first met each other.
That year, she was three, and he was three and a half years old.
Qi Ji decided that he would make up for the things that he had missed in the past one by one, and realize his bucket list. He would start with getting his childhood friend engaged to him."
