This episode gets me wondering about one thing, that is how hard it was to keep his issue as a secret for the past 11 years. It is remarkable that he managed to hold on for that long, living his life without opening up to other people, save for his secretary and his shrinks. He might have never encountered someone who willingly holds out a hand towards him, offering the comfort he needs. I can’t blame him for being cautious with the people around him, because his immediate family cannot even function as the bomb shelter he needs. He is indeed lucky to encounter Ri-jin, who won’t judge him based on his mental issues and accepts him for what he is, multiple personality or not.
