No, the setting they’re in right now is the ending of the novel. Why Hestia knows what will happen next is because she transmigrated in the novel’s world AFTER the book ended and she knew of Kael’s death then she came back to again the end of the novel but this time she’s trying to prevent his death. Things are not going how they when she started living in the novel in her previous life because of her intervention and thus will cause the butterfly effect.

Hmm... Then maybe it's just me, I imagined this part in the novel differently coz from what I remember these scenes were all about hestia, the lady gossipers and Helios. Kael was of course mentioned but he doesn't do much nor did he told Helios that hestia won't be visiting anymore. Might be mistaken....
Chapter 66 here in the manhwa is also different from what I remember, but maybe it's just my aging faster than me memory...
