Ever since, he refused to allow anything to move his heart. However, after meeting Yeo Reum, he decides to work at the airport for a bit longer and also becomes interested in her.

Ian Santos, a Filipino, is caught trying to enter Korea with a forged passport. He begs the Immigration Office to just allow him to be with his wife while she gives birth and promises to leave the country right after. However, he is forced to go back to the Philippines right away. While on his way to the plane, he pushes an accompanying staff worker and runs.

A plane tries to land at Incheon airport. However, as the plane descends near the airport, fire erupts from its engine, and the entire airport falls into chaos. Soo Yun finds Yeo Reum being extremely nervous and finds out that her mother is on that plane. After thinking what he could do for her, he decides to find Yeo Reum's mother himself.
