Marriage By Document Swap — But Fate Grants Love!

Mark, a young medical student, just graduated from college and learned a shocking truth: he has been married for two years — thanks to his cousin Ethan's document swap! To get a divorce, he had to travel to a remote military garrison on the desert border, where he is awaited by Regiment Commander Sofia King — a cold, honest, and experienced officer.

Mark planned to live for exactly one month, play the role of a husband, and then return to the capital to his usual life. But the harsh conditions of the barracks, Sofia's silent care, who brings him food and looks after him, and his own medical skill (he has known Chinese medicine since childhood) begin to change his views. When Mark saves Captain Miller's wife from a stroke using acupuncture, the entire garrison sees him not as a spoiled boy, but as a real doctor.

But the main test comes when Mark stands before the divorce document with a pen in his hand. Remembering Sofia's tenderness, her silent support, and respect for his weaknesses, he realizes: this is not a trap of fate, but its gift. Mark refuses the divorce and decides to stay — to learn to cook, work as a doctor, and build a family with the woman he initially wanted to leave.

How do two people from different worlds find eternal love on a desert border? Why does a marriage by mistake become the strongest union?
