And actually, she is not really thinking of changing her image (she thought about it because, well her stepmother watched her dramas and hated her before meeting. After a while, she really realises that she also likes the villainess's roles. But we dont know if she plays it later because the novel is too short ;_;.
After half of the novel, she is in a stable and serious relashionship with the ML. Well, her image changed after a streaming broadcasted live for her birthday. She gained fans who liked her, on the contrary with her "love to hate her characters"-fan base. So she is still playing the role of a villain.
