She is a mortal with a serious illness and is destined not to live past the age of twenty. When she was fifteen years old, the snowy jacaranda tree spirit that had been guarding her for fifteen years in front of the courtyard window came into her life, and they had known each other for four years. She did not know his origin, and thought that he would die of illness in this life. She never thought that the tree spirit named Gu Shiyue would draw blood and cut out her heart to prolong her life. Since then, she has been immortal and wandered around the world, and he disappeared without a trace. In order to find him, she traveled thousands of miles across mountains and rivers. In order to save him, she experienced all the ups and downs in the world. In order to stay with him, she saw all the love and hatred in the world. Can Meng Shisan, who has gathered thirteen memories and thirteen obsessions, bring her Gu Shiyue back to life? Heaven doesn't know, earth doesn't know, and she doesn't know either. Perhaps because of her century-old obsession, Gu Shiyue never really left. Maybe one day, he would be just like when he first met her, smiling and coming from a distance, holding her hand and saying, "Ajin, I'm back."
Concept: Every love in the world has its unforgettable memory, and the obsession that cannot be let go may lead to encounters in the next life. If there is another shore in your heart, then there is a ferry. May your heart be filled with joy and find perfection, and may all the love and affection in the world find its destination.
