Mayonnaise

A anthropomorphic wolf in a lab coat sits at a table with a tray of dumplings, holding chopsticks and looking at a human boy with red hair who is sitting at a desk behind him, holding a bottle and looking concerned; the wolf's expression changes from calm to a wide, excited grin as he opens his mouth and raises his free hand. The scene takes place in a classroom or laboratory with bookshelves in the background.
