Hyeonseo’s South Korean boyfriend. Hyeonseo first meets Kim in Shanghai, where he is on a business trip from Seoul, and they immediately begin spending time together. Hyeonseo and Kim date for several years, and Kim never once suspects that Hyeonseo is a North Korean defector. After she finally tells him, Kim supports Hyeonseo’s decision to seek political asylum in South Korea, and he later supports Hyeonseo’s decision to bring Mother and Min-ho to South Korea, too. Kim constantly worries that his parents won’t accept Hyeonseo because she is North Korean, and he often encourages her to go to the university and become a doctor or a lawyer so they will accept her. Not long after Mother and Min-ho make it to South Korea, Hyeonseo breaks off her relationship with Kim, claiming they don’t have a future. Kim agrees, and the two remain on friendly terms.
