[The absolute callout of a look makes her giggle at a higher pitch than she likely should, but she forces herself out of that to hear Lup's answer. And it's... a little surprising, actually. Knowing them and hearing about certain things in their relationship, she would have thought some big sweeping confession was in order.

I mean, uh, it must be really amazing to have someone who you share so many interests with.
