The revenge Hestia want is the protagonist MC to say sorry but the protaMC didn't want to do that so Hess want the protaMC feel what Kaelus feel back then to make her understand. And why is that? Because she is back to the past for that reason and if Kaelus didn't want for that then what is her purpose to go back (come to the novel)?
Like you have a reason to live but someone stripped it from you, just like that.

She didn’t really have one sole purpose. It was both saving ML and having the revenge. She grew to hate them and worked hard to achieve her goal. So to have the hard work be stopped, made her feel like she did everything for nothing. This isn’t about what ML wants, FL wanted revenge on her own too. Sure it’s not what ML wanted, but FL doesn’t have to agree with everything he wants just cause he’s her beloved favorite.
Idk imagine it like a movie where the protagonist seeks revenge and then by the end of the movie the protagonist is like “no, I won’t do this anymore! I forgive you!” It’s so frustrating as a viewer to have gone on that journey just for it to be pointless.
Sorry, what? Hestia is losing her mind for what?
I don't think the manhwa depicted this clearly. Because why is she tweaking because Kael doesn't want to take revenge on Diana?
He never implied any desire to take revenge on Helios and Diana. That was all Hestia.
Kael wants to live a happy married life with Hestia. I don't understand why she can't see that.
She talks about her sole purpose being revenge. But her sole purpose was to keep Kaelus alive and to support him.
Revenge didn't have to be the main thing. And Diana is already losing her place in the worl.
I really don't understand Hestia's overreaction.
