Moon Geun-young revealed the secret behind her tearful acting.

On SBS's "Our Ballad Season 2" (hereinafter "Our Ballad 2"), which aired on the 5th, a contestant appeared who selected an OST from the drama "Autumn in My Heart."

Prior to the appearance of the contestant who chose "Prayer," the OST of "Autumn in My Heart," footage from the drama 25 years ago was shown during the broadcast.

Following this, Cha Tae-hyun turned to look at Moon Geun-young, and Park Kyung-lim asked, "You played the child counterpart to Song Hye-kyo, right?" At the time, Moon Geun-young, a 13-year-old middle school student, received immense love for appearing as the child counterpart of Song Hye-kyo.

Upon seeing the footage from "Autumn in My Heart," which marked the beginning of her title as the "Nation's Little Sister," Moon Geun-young could not hide her embarrassment. She shyly remarked, "Decades have passed. It feels like such a long time ago."

Regarding Moon Geun-young's masterpiece-like tearful acting, Jun Hyun-moo asked, "How were you able to shed tears so well?" In response, Moon Geun-young brought laughter by saying, "I'm not really sure. I only remember just crying whenever they told me to cry."
