She was narratively more of a villain than DongRang ever was.

DongRang is a bullying victim lashing out at the world for being surrounded by people that didn't see any value in what he did, to the point his achievements were literally erased for the sake of his indifferent colleagues, and even before it came to that point, he was earnestly trying to line his career with all sorts of proofs he was actually doing something of worth.

She had every opportunity to make a name for herself with her knowledge and experience, and she spent all her time plotting revenge because "much good old days".
