Am I Doomed for Treating My Real Heiress Sister Like a Lackey?

I, Su Wuqi, am struggling to survive in the world of a ridiculous romance novel. This world is full of malice toward me, and my sister, an embodiment of natural disasters, is searching for me. Luckily, this world hasn't completely done me in. In this bleak life, I still have a little follower who never leaves my side. I also tell her all about how much I resent my sister. Until one day, I saw my little follower at my sister's birthday party. Having transformed from an ugly duckling into a swan, she came up to me and gave me a wicked smile. "Hello, my dear little sister."
