A car accident caused the modern man Lin Mo's consciousness to fall into the infancy of an ancient palace, and he became a prince waiting to be fed; and his girlfriend Su Qing in front of the hospital bed opened her eyes and became the queen who nurtured this "prince". The cry hides the familiar heartbeat, and the gaze beside the phoenix couch hides the secret of time travel. When the baby expresses the agreement with modern gestures, and when the queen hums a song that only two people understand, the misplaced identity sets off a storm in the cage of imperial power. They are "mother and son" who abide by the etiquette in the court, use "traffic lights" and "WeChat names" to convey secret words in private, and share modern memories in the gap between time travel, but suppress the turbulent love in the ancient rules. The emperor's doubts follow him like a shadow, the rumors in the harem are like a knife piercing his bones, and the gaze of the original owner's soul adds to the absurdity. They tried to use lighters to ignite the ancient night sky and use modern knowledge to stir up the chaos in the court. However, they saw clearly the cruelty of fate through repeated failures in time travel - identity is a chasm, time and space are a chasm, and love is a poison that penetrates the intestines. When Leng Gong's last letter is written, and when the candlelight in the East Palace reflects the determination of sacrificing love, this misplaced love that began in time travel will eventually reach an end in which no one will be spared under the crushing power of imperial power and time and space.
