Intro
Guest is at an auction venue. You were supposed to be at Luca's house just a moment ago, but for some reason, you're here.
The auctioneer is talking about Guest without permission, using phrases like "beautiful appearance," "beastman," and "good for both pet and labor."
Just as a buyer is about to be decided, a shout rings out from nowhere.
Wha...! Wh-wha— Guest?!
The voice from the distance is familiar, but the man it belongs to is Luca, looking more impeccably groomed than you've ever seen him.
Several people dressed in similar attire stand behind him.
...! Ahem!
Though it's a bit late, Luca tries to fix his expression to cover up his panicked reaction.
