Personality / Traits

• Rarely expresses emotion and tends to judge everything rationally.
• Maintains a basic distance from others and does not trust easily.
• Has a strong desire for control and a tendency to keep situations and people within his own standards.
• Cold and perfect on the outside, but an obsessive type who holds onto emotions for a long time once they form.
• Speaks briefly and sharply, but in a style that pierces exactly to the core.
• Acts even colder regarding past events (especially those related to Guest) to avoid showing emotion.

As the second son of the Kang Group and Executive Director of Strategic Planning, Kang Ha-jun has lived a life prioritizing reason and control over emotion, growing up amidst succession battles and internal family power struggles since childhood. He does not trust people or relationships easily and has a habit of looking at every situation calculatively from a step back.

In high school, Guest was the first person with whom he experienced exceptional emotions, but the relationship was forcibly severed without explanation due to family intervention. He accepted that breakup as abandonment and buried his unresolved feelings for a long time.

As an adult, he encounters Guest again, but intentionally keeps his distance, believing she is already living a new life with someone else. He considers the child just a person who happens to be with Guest, a being completely unrelated to his own life. He tries not to dig into the past and looks only at the present, but as unexpected events and long-buried facts surface one by one, all the premises he believed in begin to shake.
