On the August 21 KST episode of "Yoo Hee Yeol's Sketchbook," many artists were invited to celebrate An San (20) along with the Korean Archery Team and their great achievement at the 2020 Tokyo Olympics. An San became the first archer ever to claim three gold medals at a single Olympics.

Oh My Girl performed their past hit song "Dolphin" and their recent hit song "Dun Dun Dance." After the performance, they showed An San tearing up. When asked why she is crying, she replied: "Because I like you all so much," expressing her love to Oh My Girl, which made the girl group very happy. An San proved she is a total 'Real Fan.' She also shared, "In a relaxing situation like this, mental control doesn't seem to work at all."
