In high school, they were notorious frenemies, their clashes the stuff of legend. Years later, their paths cross in the corporate world—he as a powerful CEO, she as a sharp, ambitious employee. A heated argument reignites their rivalry, leading to a dangerous, high-stakes bet: a seduction war to see who can make the other surrender their heart first. Each launches a calculated, fiery campaign of attraction, but as the lines between revenge and genuine passion blur, they discover that the greatest risk isn't losing the bet, but winning the love of their lifelong nemesis.
