I don't ask how, because we know they come from a kinda calligraphy blah blah ok, but why do they exist? I mean, who saw the ね ancestor and think "dudeeee we can use that as an syllabary and this specific one is going to be something like "ne" o "re" maybe, I don't know" and later on, combined hiragana use for grammatical use and stuff like that
