Vianna chuckled softly as Ferris asked her what the kiss had been for. "Are you going to ask me that every time I spontaneously decide to kiss you, Professor?" she asked, raising an eyebrow at the boy just very slightly. She chuckled softly once more, amused by the boy's question before continuing, "I just felt like kissing you," she confessed with a shrug, giving him a large and not necessarily apologetic smile.
