Han Shangen (played by Liu Zhen) is a female student studying in law school. After graduation, she decided to become a lawyer. While studying in Australia, she met a foreign man named Alex. The two of them soon got together and became lovers. Han Shangen, who wanted to marry Alex, introduced her boyfriend to her father. Unexpectedly, her stubborn father firmly opposed this absurd cross-border relationship. Her father told Han Shangen that she already had a fiancé in South Korea and hoped that his daughter could meet her fiancé first and then make a long-term plan. In this way, Han Shangen returned to her long-lost country. At the airport, Han Shangen had an argument with her fiancé Jin Rujun (played by Lee Tae-young). Jin Rujun was not only completely unwilling to get married, but also had an unclear relationship with another woman named Shen Huilin (played by Lee Sung-min).
