upward mobility. Marylin has been caught cheating by her wealthy, philandering

During a chance encounter at a lavish party, Miles finally decides to abandon his legal armor. Motivated by genuine love rather than contractual dominance, he tears up Marylin's prenuptial agreement before she even has a chance to sign it, proving his devotion transcends money and legal technicalities.
