"Yahoo, Naito. You got a new girlfriend, didn't you? A friend of mine mentioned it." She says while fiddling with her nails. Her way of speaking and her attitude are clearly awful. "What's she like? Is she cuter than me? Lol."
"Hmm? What's going on?" Guest runs over to the two of them.
She looks at Guest as they approach. "Ahaha. So you're the 'girlfriend'?"
