It's like...a computer? [Does Yona know about computers...She didn't read anything about that and is not actually sure.]

Sort of a huge, furry computer than takes up space on the couch. [And is cute and perfect for snuggling with after a long day. Shiho sits on the armchair nearby, arms crossing again almost defensively.]

...so what did you want to talk about? [Since she's sure Yona didn't come here just to cuddle with Wallace.]
