Who is Jaehee's fiance?

Young and Jaehee's friendship is disrupted by multiple changes in Jaehee's life, including her relationship with a serious boyfriend, who becomes her fiance and then her husband. This relationship represents a move away from the chaotic but fun times Jaehee and Young have drinking and meeting men together, and a move toward stability. Young states, "he had a kind of stability that Jaehee and I didn't have, a fundamental optimism toward life" (33). Jaehee meets this man at the electronics firm where she is hired while still in college. He is also described as "down-to-earth," and Jaehee notes, "He does everything I suggest, like a pet dog" (39).
