ENA's greatest theme is regret, which also tells us a little bit about how the beings in this world work
she is constantly acting out in ways she regrets later, her sides aren't separated into happy vs sad, they're separated into emotionally controlled vs overemotional, and the overemotional side is constantly doing things that the more controlled side apologized for, she is fully herself when she acts in either way and that's why she feels the need to apologize and regrets her actions later, and why she never expresses the notion that her sides are separate, she is wholly responsible for her own actions and she knows it but she just can't help herself at times
she doesn't care if you call her a scammer because that's to do with her business and she clearly loves her work in earnest, she doesn't care if you call all ENA terrible because that's just an aspect of her inherent nature, she doesn't mind anything you say, no matter how rude you are to her or what your preconceived notions of her are, she never once had a melty up until she was reminded of something she HERSELF did, whatever pic rel represents- not something someone is accusing her of based on her reputation, not something that's affiliated with her work, but something she did personally in her own past, only THEN does she finally freak out, because that's something she actually regrets, something she presumably did in an overemotional outburst that she now has to live with the consequences of
the whole theme of a hangover is also directly correlated with regret, note than ENA never drank or did drugs, we never saw her partaking in any of the activities that would lead to the hangover because THOSE aren't the focus, just the aftermath, her story is themed around regret and because her character is correlated with regret is also why she can't be forgiven, not because of WHAT she did, but because she as an entity is the symbolism OF regret, it's not a metaphor, it's what she is, a being representing regret, and it cannot be removed from her because that's what makes her what she is
it's also why Frank can't be forgiven, he is Frank the UNFORGIVEN, without that, what is he? the state of being of the entities in this world is nonphysical, so it hinges entirely on ideas, the only way you can destroy them is destroying the ideas they are built around
