He distorted her. Slowly. By trying to morph her into someone she's not. She was being changed against her will. By saying that she looks better in white, she sold all her black clothes. He gave her roses which immediately became her new favorite flowers instead of bluebells. Without thinking, he tells her that she's way prettier without any roll on her stomach - so she immediately started working out. She started to change herself. She shed all of the weight that was considered 'disgusting' by the boy she loves most. Her eyes grew darker and her skin became paler. Lifeless. As if all positive energy was drained from her soul and now she's just a skeleton.
A mere lifeless skeleton.
