Lee Sang-min commented to Park Woo-yeol, "Woo-yeol has met a woman he has never met before."

He added weight to the story by mentioning his past. "What resonated with me more was that I also dated for a short period and then got married. Someone like Yu-gyeong was the one who changed me. That's why it touched my heart more," he said, mentioning his wife. His real-life experience of marrying after a short courtship overlapped with the contestants' situation, leaving a heavy lingering impression in the studio.
