Eliza was probably inspired by a whole lot of African-American women I've seen pictures of on social media, and in hair tutorials and more, along with my own personal hair-struggles, entrepreneurialism, and go-getter attitude.
Ruby: I think is largely inspired by me and my sibling's senses (or sense, because we're pretty in-sync and they're often more or less the same) of humor and savagery. But physically, idk. I guess a but by the business-y sort of tomboy thing I feel like I've seen in anime art, and also designed into a lot of my own stories before.
Aaron: I think is inspired by some AMBW couples I've seen on YT as well as the fact that I just like writing AMBW couples, and also how common it is for Korean's to run beauty supply stores.
