This book is about a person who repeatedly opens the door and another person who repeatedly waits for him behind the door.
Every time Shen Ci was reset, he would forget who Lu Shiyan was. But Lu Shiyan would find him within three days every time, stand in front of him, and start with the same sentence: "I'll pick you up." He wrote down eighteen worlds in the memo - the soft-boiled eggs should be simmered for one minute and forty seconds, the sugar in the cinnamon rolls should be reduced by half a spoon, and the scarf should be wrapped twice before being knotted. What he remembered was not the taste, but Shen Ci. His spiritual body was that of a Samoyed, and his tail would wag crazily when he saw Shen Ci. His mental picture is of a fairy tale town where every leaf of the tree has the same name engraved on it.
He said: "Every life, I will learn it all over again. Chase you again, kiss you again, and look at you again the way you looked at a stranger when you first saw me."
This is a story about waiting. A story about "No matter how many times you forget me, I will make you fall in love with me again." Eight doors, eight reincarnations. Open the door and it's you in the light.
