Garurumon stares at Stacia for a moment and then says with a frank tone that definitely didn't need any of the Valentine's Day event to come out:

"Hah...I can't imagine you biting a raw heart at all. You don't look like someone who would."

Mostly because he's aware humans are a tad persnickety when it comes to, as she said it, cooking and the such. Nobody here looks to him like they'd survive a day by themselves out in the wild. Garurumon has a tendency to underestimate others, truthfully, and enough lack of consideration to let it be known to their faces.
