In a car accident, architect Shen Yan and his five-year-old daughter Tangtang both became vegetative, and their souls accidentally misplaced themselves and possessed others. The calm and reserved Shen Yan lives in the body of 19-year-old rebellious boy Lin Yue; Xiao Tangtang, who relies on her mother for everything, is trapped in the body of 42-year-old single mother Lin Shuyue. Only by collecting the nine memory fragments and finding out the real culprit of the car accident can their souls be restored.
Opposite them lives Gu Wan, their wife who has been waiting for them for two years.
Doors 301 and 302 are opposite each other. They are so close but they are the farthest away from each other. Gu Wan clearly noticed that the casual college student next door and the gentle proprietress of the cafeteria looked like they cared about her day and night.
But heaven has set a shackles: Shen Yan and Tangtang can never recognize each other directly. The name I wanted to say came out empty, and the handwriting faded in an instant.
Everyone's regrets are quietly fulfilled in this dislocation, but they are full of sadness.
After ten years of deep love, Shen Yan never said a word of love in person. Now, with the help of the young man's voice, he finally speaks the confession that Gu Wan has been waiting for for ten years; Tangtang, who is used to relying on her mother for everything, is forced to grow up independently, learns to dress herself for the first time, and bravely says "I will do it myself".
The rebellious Lin Yue understood his mother's silent love, the strict Lin Shuyue learned to let go and trust, and the ten-year estrangement was eliminated.
Gu Wan never gave up on investigating the truth of the car accident, from searching alone to four people working together. As the memory fragments are unlocked layer by layer, the truth of the car accident slowly emerges.
The ninth-level fragments settled, and the real murderer was finally brought to justice. All belated confessions, growth and reconciliation are fully realized. The only price is that everyone has waited too long.
