Cyan was Sunshine's younger half-sister. They were very close, seeking each other out most out of anyone. They often just "chilled" with each other. Sunshine believed whole-heartedly in Cyan, but recognized she had issues she needed to work out.

Scarlet was her younger half-sister. She did realize that Scarlet didn't have a high opinion of her, but still strived to treat her with kindness, as she did to everyone. She always hoped that she'd win over her heart fully. She never did recognize the biggest reason Scarlet disliked her was not her herself, but her mother Quartz.
Sunshine was Scarlet's older half-sister. She saw Sunshine as dumb, naïve, and hated the fact Quartz used her like a puppet. But she also hated herself for thinking those things, still recognizing that Sunshine was undeserving of the critism, especially as Sunshine was always so kind to her.
