Lin Du, who was in the late stage of lung cancer, inherited a Shixu convenience store that was only open at midnight. It connected the time gap from 1987 to 2035. Customers exchanged precious memories for the opportunity to change their regrets. Every time he completed a transaction, he would lose a piece of his own memory. When he discovers that the fate of all his customers is entangled with his family's destiny, and that even his name and identity are lies that have been tampered with, he must break the deadlock of reincarnation between saving his father, saving the world, and saving himself.
