Living With My Flirty StepbrotherUpdated at Jun 26, 2026, 03:12
"Our parents didn't just blend our families—they signed a contract. Now, the arrogant billionaire heir who makes it his personal mission to ruin my study sessions is officially ruined.
At eighteen, Sierra is already a certified teenage billionairess, fully capable of managing her own empire but forced to navigate the chaos of her final school year. Her perfectly structured life is completely derailed when her father remarries, and she is forced into a high-stakes arranged marriage with her new stepbrother, Julian, to secure a massive corporate merger.
To the rest of the world, they are a gorgeous, picture-perfect couple in the making. In reality? It’s a total love-hate war zone.
Julian is relentlessly charming, infuriatingly attractive, and a professional flirt who knows exactly how to push Sierra's buttons. He doesn't care about corporate rules; he only cares about breaking her icy exterior. Whether he’s playfully stealing her pens while she’s trying to study, crowding into her personal space on the living room sofa, or flashing a devastating smirk just to see her blush, he makes living under the same roof an absolute test of willpower.
Sierra is determined to hate him and protect her heart from his effortless charm. But as the forced proximity wears them both down, their hostile banter begins to shift into an undeniable, slow-burn attraction. Behind the playful teasing and the arranged contract lies a scorching chemistry neither of them can ignore.
They start as bitter rivals forced into an alliance, but as lines blur and secrets are shared, they might just find their way to a real, hard-won happy ending.
