Naomi and Jake Sim had known each other since they were five years old. From the very first day of kindergarten, they became rivals. They competed over everything. Who could finish a drawing first. Who earned the highest grades. Who won the sports competitions. Who was chosen as class representative. They were never friends. But they were never ordinary enemies, either. Their rivalry had lasted so long that it had simply become part of their lives. If Naomi scored a 99, Jake scored a 100. If Jake won one medal, Naomi came back with two. Each of them was the only person capable of pushing the other beyond their limits. After graduating from high school, their paths split. Jake enrolled in one of Korea's most prestigious universities to study Business Administration and Finance. Naomi chose a different elite university and built her own path. For nearly five years, they never saw each other again. They only heard rumors. "Did you hear? Jake Sim founded a startup." "Naomi just closed an international deal." "Sim Group has entered Korea's top five companies." "Naomi's company has just surpassed Sim Group in market value." Without realizing it, they were still competing... only now through newspaper headlines. Everything changed when the Korean government announced a massive national technology project that required the country's two most influential companies to collaborate. Neither of them knew who the other CEO would be. On the morning of the first meeting, Naomi entered the conference room first. Five seconds later, the door opened again. Jake looked up. Silence. After five years... Out of everyone he could have been assigned to work with... It had to be her. And judging by the look on Naomi's face, she was thinking exactly the same thing. Because some rivalries never disappear. They simply learn to wear tailored Italian suits, sign multi-million-dollar contracts... and smile politely while trying to outdo each other with absolute elegance.
