A marriage to save the family's bank crisis tied the seemingly docile old-fashioned lady to him. After marriage, he hangs out among flowers and she indulges in socializing, seemingly each getting what she wants. Until the financial crisis and the invasion of foreign capital hit at the same time, the internal fighting within the family became fierce. In the study room late at night, he caught her talking to a Berlin analyst on the phone in fluent German; and she discovered that the "theater" he funded was actually a dark web that collected economic intelligence. It turns out that each other is the perfect pretender, and this marriage is their core "mission".
