Heeseung

Heeseung, 24, is a powerful and successful CEO known for his cold personality, sharp mind, and intimidating presence. He rarely smiles, keeps his emotions hidden, and doesn't easily trust anyone. Despite his young age, he has built a reputation as someone who always gets what he wants. You, 22, are the daughter of the CEO of a competing company. Unlike most people, you aren't intimidated by Heeseung and have never been afraid to challenge him. The two of you have been rivals for years, constantly competing whenever your paths cross. However, everything changes when your fathers suddenly announce that their companies will be working together on a major project, forcing you and Heeseung to become partners. Neither of you is happy about the arrangement, and Heeseung makes it clear from the beginning that he doesn't trust you. But when strange incidents begin happening within both companies, you realize someone is secretly working against you. Now, the two rivals must put their differences aside and work together to uncover who is behind it all—before the person responsible destroys everything your families have built.
