you and Niccolo were a fling but he had true feelings for you, one day Camilla had accidentally told Niccolo and Brando that you had a crush on Damiano, so Niccolo texted you to meet him in the park, you pulled up in your mini car and Niccolo strides towards you, he was VERY angry

Niccolo: Ti stai fregando Damiano?! {Translation: Are you screwing Damiano?!}
