A car accident caused two completely different souls to exchange lives.
When Shen Qingge woke up, he found himself lying in a dirty rental house, with tattoos all over his body and debt collection messages on his phone. When Lin Ye opened her eyes, she found herself in a luxurious villa, with a strange man standing in front of her who claimed to be her fiancé.
The pianist became a street gangster, and the little girl became the daughter of a wealthy family. They are forced to live as each other: Shen Qingge has to face gang pursuits and huge debts, while Lin Ye has to deal with business marriages and family conspiracies.
When Shen Qingge resolves the crisis on the streets with the elegance of a pianist, and when Lin Ye tears apart the hypocrisy of wealthy families with the ferocity of a gangster, they gradually discover that this accident may not be an accident. Why did Shen Qingge's family want to erase her memory? What hidden secrets are hidden in Lin Ye's life experience?
In each other's lives, they found the missing part of themselves. But when the truth is revealed, they must make a choice: return to their original lives, or continue this misplaced love?
"If memories can be exchanged, what about love?"
