When a fearless new girl refuses to bow to the school's untouchable queen, rivalry ignites into obsession. What begins as a battle for power turns into something far more dangerous, an attraction neither of them can afford to name.

Detective Jang Wonyoung has the perfect life until a new murder case mirrors crimes from over a decade ago. Her investigation unravels a secret she never imagined: her loving wife, Ahn Yujin, is the daughter of a notorious killer. As the past claws its way back, lies, love, and blood collide and Wonyoung must decide if the truth is worth losing the only person who ever felt like home. A/N: Inspired by watching Flower of Evil a million times.

Every Wednesday, Noh Yunah finds a letter waiting in her locker that is anonymous, thoughtful, and written with a familiarity that lingers. She never asks who it's from. Park Minju lives quietly on the edges of the same school, keeping her world small and controlled. Writing is the only place where she allows herself to be honest. As senior year unfolds, routines begin to shift, and what has remained unsaid for years starts to press gently but persistently toward the surface.

An arranged marriage between two women who swore off love. One hides from touch. The other doesn't believe in staying. Neither expected the silence to feel this loud.

Minju is top of her class, quiet, focused, and allergic to school drama. Noh Yunah is everything she can't stand: popular, loud, reckless... and rumoured to leave a different girl heartbroken every week. When Minju is forced to be Yunah's lab partner, she expects the worst. But behind Yunah's smirk and reputation is someone unexpectedly thoughtful and deeply insecure. The more time they spend together, the more Minju starts to question what she thought she knew about Yunah. And Yunah? She's already fallen. She just doesn't believe someone like Minju could ever feel the same.

Wonyoung is South Korea's brightest star, a K-pop idol on her way to worldwide fame. Ahn Yujin is an overworked resident doctor with a passion for writing. Falling in love is easy, but it comes at a cost. Love can't be a secret for long, but does it matter, even if no one knows?

Senior year promises new opportunities and unexpected complications for Minji. Between her father's high expectations, band rehearsals, and a growing connection with the enigmatic Hanni, Minji's carefully structured life starts to unravel. Old relationships resurface in surprising ways, especially with Danielle, whose mysterious past keeps Minji on edge. Balancing ambition, desire, and the unpredictable twists of teenage life, Minji must navigate a year that could change everything.
