An accidental lightning caused William, who had a disabled leg, to wake up in another body - young, healthy, handsome, and the general manager of a seaside hotel. Unable to get close to his original body and unable to communicate directly with Jack, he can only temporarily live under Jack's name.
Work, relationships, police investigations, and the secrets Jack left behind come one after another; at the same time, he also gets closer to this stranger's family and past.
William, who originally just wanted to find out the truth and change his body, gradually found that he had become accustomed to it and even couldn't bear to part with this "borrowed life".
When the truth of the exchange is finally revealed, he must answer one question:
If you finally got the life you dreamed of, but knew it originally belonged to someone else, would you give it back?
