Just arrived in Paris, Hélène (who has never met Florestan) and her aunt, the Countess Ermerance de Champ d’Azur, now visit the shop to buy their corsages for a ball the countess is giving to celebrate her niece's engagement. Hélène is not pleased to be entering an arranged marriage. Their servant Séraphin is also eagerly anticipating his marriage and wants to slip away to his wedding feast. Florestan arrives at the shop (guarded by Loustot to ensure he does not run off) and flirts with the shop girls. Hélène and Ermerance overhear a conversation where Florestan breaks off his liaison with Agathe, in the process learning that he is Hélène's intended husband. When Florestan complains that he must leave Agathe for a simple girl from the provinces, Hélène vows to take revenge on him, although she finds him handsome.
