She then asks Oshizu about love, but Oshizu mistakes the term Koi (Love) for Koi (The Fish), leading her to tell Nana some incorrect information about how love is delicious to eat. Nana then asks Mikan if there is someone that she love, which causes her to blush but she denies having anyone of interest. Nana then tells Mikan not to count Rito, which shocks Mikan until Nana explain that sibling love is different and Mikan agrees to.

Nana then sits under a tree contemplating love. Rito then comes up to Nana, complementing her because in that moment she look more feminine and tells that there is no doubt she is a princess. Embarassed, Nana tells him to don't say weird things. Just then, Celine falls out of the tree onto Nana's face causing her to trip. But Rito catches her.
