An accident breaks the gears of fate, and when the 28-year-old professional elite wakes up, he is trapped in the soft body of an 18-year-old girl; while the 18-year-old girl who should be sweating in the youthful campus, but with the wrinkled face of a 60-year-old man, is out of place in the morning training team. When the mature soul in suits and ties collides with the girl's body, when the innocent girl's heart is trapped in the skin of old age, and the absurd daily life of misplaced identity hides the emotional bonds and self-salvation that transcend age. Behind the reverse growth and exchange of souls, is it a joke of fate or a hidden guide? See how they piece together the puzzle of life that belongs to each other in their misplaced lives.
