Suishou, Mermaid, Fuuma, and Arashi are okay for now (relatively).
But Hima, Sakura, and potentially Yumi could stand for healing. Especially the first two (although Sakura's and Kobato's talk about their homes being one of the stars would probably have earned Kobato a healed candy or two, admittedly).
Hima right now is kind of a hot mess, since her curse went haywire. So basically Kobato just being nice to her would lead to making her feel a bit better - especially if Kobato mentions them being friends at all.
Sakura, too, could use cheering up because even though her famiree has shown up again recently, all the canon shenanigans just makes her sad. And what the recent event did to Real, too.
