Romeo, who was 18, went in July, 2018, to his girlfriend Jan, who was 19, and borrowed $5000.00 for his college tuition, promising to repay the money without interest on November 1, 2018, when his student loan came through. Romeo didn't register for college but in September, 2018, used the money to take his new girlfriend Juliet to Las Vegas for a week of fun, spending all of the $5000. When Jan learned of this she was furious and demanded that he repay the money. Romeo refused to do so. She then sued Romeo alleging breach of contract and asked the courts to order him to return her $5000.00.
