Honestly, I like that they didn't just made the brother an awkward guy would couldn't show his sister that he cared and the sister just becoming evil on her own. They used to be close, but he became jealous of her for reasonable reasons for a child of his age. But he didn't become a jerk who bullied her, he just drifted from her, unfortunately he also became cold, and by the time he realized he made a mistake, it was too late.
Og Yvonne couldn't understand him, not bc she was too dense but because she was too young to get it and no one explained this kind of stuff to her. She ended up resenting him for abandoning her and becoming cold without any explanation. Which is, again, reasonable.
Being abandonned by her brother (probably with other factors) led to her change. But at some point she pushed others aside so much that she ended up alone, hence why she would fall for the cp so fast, she ended up craving for kindness so much that the bare minimum was enough...

I have no regrets in meeting you, friend. Should the day ever come that we are not together, you will continue to shine like gold in my memories.
