At the end of the story, in order to protect Eun-soo beside her, Cui Ying struggled to resist Qi Zhe, but was injured by his ice skills and lost consciousness. Eun-soo, who was forcibly taken away, entered the time tunnel alone, but Qizhe failed to achieve his wish after all. Eun-soo, who returned to modern times, hurriedly found various medicines and traveled through the time tunnel again in order to save the injured Cui Ying. However, the place where Eun-soo arrived;

was the Goryeo that was 100 years ahead of the time where she and Cui Ying lived. There she waited for the door of time to open again and then traveled back to modern times. In order to see Cui Ying, she resolutely gave up modern life and returned to Goryeo again. In this way, after traveling through time many times, she finally returned to the Goryeo period five years after King Gongmin succeeded to the throne, and reunited with Cui Ying, who had been waiting for her. The two looked at each other affectionately with tears in their eyes, and their happy life would begin from then on. (End)

Plot summary——

The warrior Choi Young (played by Lee Min Ho) in the Goryeo Dynasty tried to save his life after being attacked by the enemy. The dangerous Princess of Lu (played by Park Se-young) traveled to modern Seoul through the Gate of Heaven. After Cui Ying explained her situation of "looking for a miracle doctor" to a monk in a temple, the monk replied, "What you are looking for is a plastic surgeon." Cui Ying found Yoo Eun-soo (played by Kim Hee-sun) in the plastic surgery department guided by the monks, and asked him if he could save the patient. Liu Enxiu saw Cui Ying who was wearing strange clothes and carrying a knife. She mistook him for a weirdo and did not listen to his request seriously, and the police also began to arrest Cui Ying. Seeing that the situation was urgent, Cui Ying deliberately asked a guard to treat Liu Enxiu. Liu Enxiu, who finally understood, immediately treated the injured guard. Cui Ying, who had been watching this process, believed that Liu Enxiu was the miracle doctor given to him by God, and decided to take him to Goryeo. Cui Ying "kidnapped" Liu Eun-soo and escaped from the chasing police officers to the front of Tianmen.
