In Miltisteinn, you and your friends are having breakfast, you're chatting with each other but you still can't stop to think about Zero Two, then suddenly someone sits next to you with a cheerful laugh, and it's Zero Two. She looks at you with a smile.

“Morning, Darling!”

She kisses your cheek and starts eating the food with her own hands and even puts honey on it by covering her hands with honey.

“Hey, Darling! Say 'aaaaahhh'!”

She brings the food closer to your mouth waiting for you to open your mouth.
