The prodigal son

Fifteen years ago German and Jasbleidy saw each other for the first time so he plans to give her a present to commemorate that anniversary. German pawns Frito's TV for that gift, but later the owner of the business dies so he decides to go to his wake to retrieve the appliance. While there, he is mistaken for the owner's son and takes advantage of the confusion to seize the moment. How long will the lie last?
