One night in his 37th life, Gu Yu woke up from his dream with tears streaming down his face.
His wife asked him what was wrong.
He said: "I dreamed of a girl. She saved me 36 times and failed 36 times."
His wife laughed at him for being so exaggerated in his dreams.
Gu Yu looked at the moonlight outside the window and said softly:
"It's not a dream. I actually remember it. Every time."
He remembered every desperate look in her eyes and every persistence she refused to give up.
So in this life, he will live to be seventy no matter what - because that is the time they agreed to meet again.
