'Nest Escape' is a reality show where minors leave home and travel overseas without any parental supervision for the first time in their lives. The cast members this season include Samuel Kim, child actress Ahn Seo Hyun, and 2nd generation children of well-known actors including Hwang Sung Jae, Sun Woo Jin, Sun Woo Chan, and Lee Si Heon. 

On this episode, the children arrived at their travel destination of Poland, and were tasked with finding the home where they would be staying on their own. The children went out to the streets to do a bit of sightseeing outside the Warsaw station, and during their walk, the camera captured one female who saw Samuel Kim and froze. 

Samuel tried to say "Hello" and interact with the fan, but she seemed too flustered and shied away. However, after Samuel passed by, the camera captured her crying in her friends' arms, overwhelmed after running into Samuel on the streets all of a sudden.
