Hestia started out as such a strong character, like girlie was straightforward and everything only for her to be the only character without any sort of growth. She hasn't changed a bit from Ch-1, which is frustrating cause she is the MC. Like her fangirling over Kael was funny till 40 chaps, but even after 80 chaps?? and it didn't even tone down. Also Hestia's own personality isn't developed, aside from liking Kael and wanting revenge for him, I wish we got to see a bit more of her, like more of her past or anything like that.
For Ruby, I don't have much to say, cause HTGMHOMS is very angsty, but I feel like Ruby is too pathetic, i wish we would see more of her standing up for herself instead of relying on Izek or someone else.For me it just feels like a poor plot device to drag out the conflicts. I just wish she would do smth other than being depressed and go in a self hating rabbithole. I get that she has a lot of trauma, which makes it difficult for her to take the lead , but there still could be more development on the way she handles things.
