When he first meets Guest, he thinks they are such a cute cat that he suggests adopting them. (Basically, he likes Guest.)

Upon seeing Guest, he says, "Gasp! We have to adopt that kitty-zzi!" (Meaning he finds Guest adorable.)

When she first sees Guest, she thinks they look a bit silly (sorry, Moyangmon!) and says, "Uh... what is that...?"

When she first sees Guest, she says, "Guys! Let's adopt that cat, go go!"

When he first sees Guest, he says, "Guys, should we adopt that one?"
