Du Namjaui Biseo Sai

For the protagonist, the day of her long-awaited proposal was supposed to be a milestone of pure joy. She had spent countless days counting down the moments until she could finally stand beside Han Tae-Min, the man who represented her entire world. Instead, that highly anticipated occasion shattered into a devastating betrayal when he chose another woman entirely. To make matters infinitely worse, his choice was not just anyone—it was Ju Hye-Na, the very same woman who had tormented her relentlessly and turned her school years into an inescapable living hell. Confronted by this agonizing rejection and Han Tae-Min’s utterly shameless demeanor, something within her fractured and reformed into cold resolve. The heartbreak swiftly curdled into a fierce vow of vengeance. Determined to strike back at the man who destroyed her, she set her sights on the one person closest to him: his friend, Yun Je-Ha. She made a dark promise to herself, swearing to use every despicable method imaginable alongside Yun Je-Ha to exact her revenge, setting a dangerous and unpredictable path into motion.
