When "Equal Treatment" Backfires Beautifully

Synopsis

I wake up one day to find I have been dropped into the life of a clueless, crazy-rich mom, the biological mother of a story's long-lost heiress. According to the plot I remembered, my two daughters are sweetly close in public, but behind closed doors, they tear each other apart over the pettiest things, like a bigger bedroom, the last slice of cake, and a cute boy. So I become Switzerland, always keeping things balanced. Clothes are bought in twos. Allowances are split down to the last cent. I even time my lectures to ensure they are perfectly balanced. I live in constant fear of one of them accusing me of playing favorites. My years of walking on eggshells come to an abrupt end the day he shows up: the male lead. I must have circled the poor guy a dozen times, my mind racing as my perfectly balanced world threatens to implode. How the hell do you split a boy in two? Just as my panic hits its peak, I spin around and see a scene that completely derails my train of thought. The real heiress, Lucy, nudges her sister with a grin, saying, "Are you into him, Stella? He's all yours. Seriously, guys are a dime a dozen." Stella just laughs, waving a dismissive hand, and replies, "Nah, you're crazy. Sisters before misters, always." The male lead gapes at them with a pale face, murmuring, "So, should I just, like, go then?"
