Han-sol and Soo-yeon travel to Paris, the heartland of cognac, for the international competition, immediately encountering cultural snobbery and professional condescension. Their presentation of 'Vintage Heartbeat' is met with open skepticism and thinly veiled disdain from European experts. Monsieur Dubois, an arrogant French distiller, publicly mocks their 'Korean cognac,' dismissing it as an impossibility. Despite the harsh reception, a few discerning palates on the judging panel acknowledge a subtle, intriguing uniqueness in their spirit. Soo-yeon fiercely defends Han-sol and their work, her unwavering loyalty to him now unequivocally clear in the face of adversity.
