6. what’s the most romantic thing someone’s done for them?

The skit in ToX2 where Milla makes up a word (POIGNANTALIST) because she is bad at verbalizing human emotions and doesn't quite get their language, and Jude just goes along with it and makes up a word right along with her (NOSTALGALIST) because he's Jude and it's cute.

10. do they like picnic dates?

Absolutely she does. Any date with food is A+ in her book, and she has read many things about picnic dates in particular, they seem to be a rather common human tradition and she is delighted to partake in same!!

15. what’s the best gift to give them?

Fancy foods. New foods. Just food?? MILLA LOVES FOOD, FOOD IS HER HOBBY and she especially loves taste testing new flavors, whether they go together or not! As a Great Spirit she really isn't in need of anything physical or material to hold onto, soooo. New experiences, especially ones related to her love for food, are good enough for her.
