[Yokuutsu]

"Still.....shouldn't be this hungry..." And Vivi feels bad eating up all this food. For multiple reasons. It makes him feel fat....and he's eating up Riyo's food. Also, deep down, there is a fear that Riyo might send him back. He's heard of that happening and nothing good is in store for those who come back. And Vivi wasn't paying attention to details. That's why he'd die while reading the book.
