Across the long river of time, Song Yu seems like a being forgotten by the ages. He has no idea how many years he has lived. Ever since he awoke, his appearance has never changed. Hundreds of years have flown by, yet he remains exactly as he was at the beginning.
In the modern world, Song Yu runs an ordinary-looking general store. But there is nothing ordinary about it. Whenever a supernatural incident occurs, Song Yu steps in, using his mysterious abilities to solve the problem.
As he faces one paranormal phenomenon after another, fragments of his past memories come flooding back like falling snow. But the memories are chaotic and impossible to tell apart from lies, leaving Song Yu deeply lost. He can no longer tell which version of himself is real. Is he the mild-mannered shopkeeper, or the mysterious man carrying secrets buried deep in his memories?
As the truth gradually comes to light, an even greater crisis looms. Can he rediscover himself while protecting everything around him?
