We’ve turned into a Hive, things are getting serious.

No. Beauty is clearly defined parameters. You can Google the golden ratio, correct proportions of the face, body, etc. Or ask Koshi, she understands this better than I do. There is also the factor of rarity, which also works. And you probably mean personal preference. Like hair color, eye color, hairstyle, style of clothing, image, etc. Out of two beautiful women, I would choose an elf, and Ment would choose a traditional wife. In such cases, beauty is really in the eye of the beholder.

It doesn't work. Out of two people with the same character, they will choose the one who is more beautiful.
