Lin Mo is an ordinary student in the city's key high school. His grades are ranked last in his grade. He has a low-key personality and a very low sense of presence.
No one knew that this ordinary-looking young man had another identity - an agent in the underworld.
Specially responsible for dealing with the lonely ghosts stranded in the world, helping them fulfill their unfulfilled wishes and sending them to where they should go in peace. Whether it is an old monitor who has been waiting for seventy-three years, a demented old man who cannot let go of his granddaughter, or a baby who died young and wants to see his mother again, they will all knock on the old wooden door with "Lin Ji Incense Candle" written on it late one night.
Lin Mo's principle is very simple: if others treat him well, he will treat others well; if others make him miserable, he will repay him a hundredfold.
During the day, he was a scumbag who was criticized by the dean; at night, he was the ghosts' last resort. He sent away souls with deep obsessions one after another, and also collected paper cranes one after another - those were the thank-you gifts left to him by everyone who left.
Until one day, he took on an apprentice.
Six-year-old Xiaoyu is born with the ability to see ghosts. She followed Lin Mo, learning to help others, learning to face life and death, and learning to keep her true heart in a world where she was "called a monster".
At the same time, the truth of three hundred years ago gradually emerged: the resentful soul released by his own hands, the seal that trapped his master for his whole life, and the "younger brother" waiting in the dark...
Lin Mo discovered that everyone he sent away was secretly guiding him to an answer——
Who is he?
