It was rare of her to smile so sincerely in this palace. Even more rare, when it came to the five year currently running around and pretending to cross swords with Roland. Despite the five year age difference between the two, their friendship had blossomed beautifully since Rose's birth all those years ago.
She wasn't sure as to why she was smiling. She had long convinced herself that she had no desire to show any love to that child. In her logic, it all makes sense. Why care for this child? Both of her parents had unknowingly rebuffed her feelings for each of them.
But when Rose tripped on a loose stone and lands face first in the dirt, and Roland is calling for her help, she's swiftly there to make sure she's uninjured, help brush the dirt off of her dress, and wipes away the tear crawling down the child's cheek.
It's for the love of her parents. She justifies once again as Rose runs off again to play. After all, love is sacrifice. She bitterly recites.
