I saw that too. I read some of the comments and people were freaking out.. So Naive. I also like her for her honesty. I'm almost tempted to think she was making a joke out of it.
What's the translation for her tags though? I though she was sad for not being able to eat XXX in front of him, not that she wasn't able to eat period. Like she would probably eat XXX in her own time, but she can't in front of her booker. I dunno.
