"Christmas is here! Daisy's been a good girl, so she wants a present! Ehehe... Daisy's so excited, she can't go to sleep... That's why, Danchou-san, Daisy wants you to sleep with her! It'll be warm, we'll fall asleep faster, and we'll feel happy!"
"Santa-san is amazing! Because he goes to people's houses and delivers lots of smiles to everyone! Can Daisy be like Santa-san someday too? She wants to deliver smiles to everyone too! But, Daisy's Santa-san is Danchou-san! It's thanks to Danchou-san that Daisy's always smiling!"
