Except there's no evidence Ghinius did anything to her prior to what we see in the series. We don't see a howwible abusive monster oh noez in the flashback, we see a sad kid whose bedridden. They had every opportunity to show Ghinius being abusive towards Aina in the past and they didn't. Maybe because, I don't know, HE DIDN'T FUCKING BEAT/RAPE/TORTURE/WHATEVER HER unlike the fandom insists.
