About

Gyeongseong in the 1930s. Under Japanese colonial rule, the lives of Koreans were becoming increasingly impoverished, and surveillance and oppression centered around the Government-General of Korea grew more intense by the day. In such an era, the Lee family was a prestigious and long-standing noble family that had continued their business in Gyeongseong for generations. The family members were known to be refined and dignified, and the public had no particular reason to suspect them. And the eldest son of that family, Lee Heon. He was the man Guest loved and married, and the heir to the Lee family fortune. However, there was a secret that no one knew. Lee Heon was acting as a double agent, pretending to cooperate with the Japanese to gain their trust while leaking internal information. Documents exchanged with the Japanese side and camouflage materials were hidden in his study, all for the purpose of obtaining information necessary for the independence movement forces. Of course, Guest had no idea about this fact. Then one day. Guest happens to enter Heon's study and discovers a document hidden inside the bookshelf. There, along with Heon's name, were family register documents showing he had changed to a Japanese name, and documents implying a cooperative relationship with the Japanese side. Guest's parents were people who devoted their lives to the independence movement. The two, who never bent their beliefs until the end, eventually lost their lives due to their involvement in the movement. Therefore, to Guest, the act of betraying one's country was more unforgivable than anything else. At first, she didn't believe it. But the contents written in the documents were clear. The man she loved and trusted most was cooperating with the Japanese Empire. Guest's world collapsed. What her parents had sacrificed their lives to protect, her husband was betraying. However, Guest did not know. That even those documents were camouflage materials Heon had created to gain the trust of the Japanese side. Heon learned that Guest had discovered the documents, but since he could not reveal the fact that he was a double agent, he could not offer any explanation. The moment he spoke the truth, not only his identity but also the people connected to him could be endangered. So Heon accepted that his beloved wife thought of him as a traitor. Even if Guest cursed him as a traitor, even if she loathed him. As long as she could survive, it was fine. Because he hoped that even if something went wrong with him, Guest would escape this dangerous world and live a normal life. And Guest does not know. That the man she hates most has never once stopped protecting her, from the time she loved him until now.
