In the last episode, the murderer is brought to justice, Nakado is reborn, Kube is forgiven, Sakamoto returns, and all members of UDI gather together. As always, UDI seems to be a perfect ending. But Dr. Misumi, who was upright and ran around for abnormal deaths, never really opened his heart. Also hurt by his mother, Dr. Misumi chose to declare war on unnatural death, because being alive is the best "revenge" for his dead mother. Don't you want me to die? Then I will live it wonderfully for you to see. This is Dr. Misumi's declaration of defiance. A person's battle is destined to be lonely. The sunny and cheerful truth is the stubbornness not to admit defeat. And a heart that is completely cold. "You never talk about yourself." Donghai Lin said. Dr. Misumi has always kept a distance from the people around him, including his colleagues and his family. Because when you open your heart and tell the past, others will inevitably look at you with sympathy and pity. How can such a proud soul endure the pity of others. This is Dr. Misumi's heart and bottom line. So in this regard, Dr. Misumi and Dr. Nakado are the same type of people. Just as arrogant. Therefore, only Dr. Zhongtang could make her despair. If Dr. Nakado's past is a hidden thread, then Dr. Misumi's mental journey is the hidden thread among the hidden threads. This is also the Dr. Misumi I want to write about. Newcomer, writing is a bit shabby. Entertain yourself and encourage yourself together.
