Spinning on her heel, she switched to a saccharine tone, cooing to her boyfriend, "Babe, I'm dead set on losing weight this time. I'll slim down to 110 pounds, and everyone will envy you for having such a knockout girlfriend!"

She played up her plight with a whiny undertone, "I just splurged on some gym wear, though, and I'm kinda strapped for cash. Can you float me some?"

His response came back as a series of muffled grunts over the phone, sounding disgustingly phlegmy, sending shivers down my spine.

Soon after, her phone chimed with the alert of a $1,000 transfer hitting her Venmo, making Olivia giggle with delight, and giving me a taunting glance.

Previously, Olivia had used heavily edited photos to juggle three boyfriends online, treating them like her personal ATMs without a shred of shame.

She always fibbed about her weight by claiming childhood hormone treatments were to blame.

At home, she treated me like a servant, commanding me endlessly, and taking my compliance for granted. Remembering how I spent years catering to her only to be repaid with betrayal fueled a fiery surge of anger through me.

With a loud "thud," I dropped the veggies onto the floor and declared, "Make your own dinner. I'm not your maid! Besides, staying single beats being like you, juggling three guys and shamelessly mooching off them!"

Olivia quickly covered her phone, her eyes blazing with fury as she spat in a hushed tone, "Megan! What nonsense are you spouting? Are you trying to get me in trouble?!"

I scoffed, dismissing her with a wave, "I'm just stating facts."

Olivia attempted to retort, but her boyfriend's irate voice from the phone cut her off, interrogating her hysterically, "You have other boyfriends?! Olivia, if you're lying to me, it's over..."

Watching her frantically try to smooth things over, I couldn't help but smirk subtly.

This time, I refused to be the fool, running around doing her bidding without gaining anything in return.

As I stepped outside, the bright sun filled me with warmth, the joy of this second chance bringing tears to my eyes.

Previously, because Olivia was my sister, I never guarded against her, giving her the chance to drive me to my demise. This time, I'm seizing control of my life and plotting my revenge.

I took a cab to the bank, withdrew all my savings, and then consulted a one-on-one nutritionist to craft a healthy eating plan.
