Heartwarming / Little Darlings (Literature)

• Most of the interactions between Sunset and Destiny, even simple things like Sunset giving Destiny her old jacket and Destiny sending her a copy of the talent show, which clearly mean a lot to each other. Even though they only meet once and mainly communicate via letters, they form a sisterly bond almost instantly and help each other through the crap they go through as best they can. Even if they're not not actually related after all, it's clear they're as close as sisters anyway.
• Jack and Destiny wishing each other luck before their performances.
• The ending. Kate is thrilled that Destiny finally gets to meet her father, whilst Sunset and Destiny are reunited and can finally openly acknowledge each other as sisters.
