The correct response is:
Readers are more likely to look forward to Mia and Karou reuniting, while the characters themselves are uncertain if they will.
This response highlights the dramatic irony present in the narrative: the readers, having been privy to the characters' journey and the underlying bond between Mia and Karou, likely feel optimistic about their eventual reunion and reconciliation. In contrast, Mia and Karou, who are caught up in their emotional turmoil and the conflicts they face, may not share the same certainty, creating a tension between the readers' expectations and the characters' experiences.
