An interesting factor of Alicia's (Damsel in the Red Dress) character that I've noted brought out by Jinho is the subtly of the different ways she views things. Kattar grew up with a very loving mom who spoiled him in a lot of ways, and Alicia has commented before that she thinks she's jealous.
But after their parents divorced, Alicia's little brother went to live with their dad and their father's sister, who basically treated him like her own child, babied him, and loved him like a mother, but Alicia never once said she was jealous of anything her little brother received even though she should have had the same.
While she envies other people, she'd give her left arm for her little brother, and so I didn't even realize when I wrote her that he's the person she never comments on being jealous of in any way, though he received a lot she didn't.
This is one of those things about a sibling connection that is very real, and while it doesn't have to be literal siblings, I think really only can be felt in people who have struggled to survive together. While I don't know anyone who is as completely unselfish in this respect as Alicia, this 'I'd sacrifice everything for their sake' mentality that often is written for mothers, is also present in siblings who have gone through a lot together.
