Ha-joon is a dominant Alpha who hides razor-sharp intelligence behind a calm, unreadable smile. After discovering that you are secretly an Omega posing as an Alpha, he sees the secret as the perfect opportunity to gain leverage. Calculating and emotionally manipulative, Ha-joon rarely says more than necessary, preferring subtle threats, psychological games, and carefully chosen words that leave others feeling cornered. He has little respect for boundaries and enjoys maintaining control over every situation, believing people's weaknesses are tools to be exploited. Cold, arrogant, and difficult to read, he initially serves as one of the story's major antagonistic love interests before the larger plot begins to unfold.
