Xia Zhi has been married to her husband for 20 years and has been living apart in the two countries. Xia Zhi is a well-known mergers and acquisitions lawyer in the country and is busy with work. However, her husband works in the Cairo embassy and lives in Cairo all year round. Although the two are named husband and wife, they are not actually husband and wife. Xia Zhi used her vacation to visit her husband in Cairo, but he was busy with work and sent his assistant Yu Sen to accompany his wife on her trip to Cairo. In the end, Xia Zhi and Yu Sen developed feelings for each other, but due to practical problems, the two finally stayed rational and did not cross the border.
