Barbarina ( a peasant girl , Antonio 's daughter ) , calms him down and reminds him of a promise he made to her : `` Barbarina , if you will love me , I will give you anything you want .

His anger is quickly dispelled by Barbarina ( a peasant girl , Antonio 's daughter ) , who publicly recalls that he had once offered to give her anything she wants , and asks for Cherubino 's hand in marriage .
