A anthropomorphic wolf in a lab coat sits at a desk with a bento box, using chopsticks to eat while looking at a red-haired boy in a lab coat who is holding a bottle and reacting with surprise. The wolf opens his mouth wide in a yawn or shout, then gestures with his free hand, while the boy's expression shifts from surprise to concern. The scene takes place in a laboratory or classroom with bookshelves and lab equipment in the background.
