If you mean Habin, it's bevause Noah was adopted into the family and she's the biological daughter, but somehow Noah developed a goft for the arts like his foster father so Habin felt like an outcast when she's the blood related child. Media was prainsing Noah about his similarity with his father that Habin debeloped a deep hatred for that. Eventually, she turned crazy about torturing Noah emotionally, physically, and mentally to the point that there was also a part when she tried to build a family with Noah, raping him, and have kids?? It was Amon disguised Noah though.
Summary: She's mentally ill.
