@Lisha Mestha I understand about why she had to lie, because at that time when she lied, she was in the bottom of her life, in which being ugly or low was forcefully engraved in her thoughts. At that time, she always thought of her life as worthless and he**, so she started to dream and thought about being beautiful like her sister, so she lied, maybe to hide her perspective of herself being ugly but maybe because she also admired and wished to be beautiful like her sister, just for society to stop labeling her as "ugly"
