Fellow actress Chae Jung Ahn commented, "I am really amazed by how she volunteered to take [Goo Hye Sun's] place. It's not an easy task for an actress."

Hearing this, Jang Hee Jin honestly explained, "I didn't think about it to that extent. If I had more time to think about it, I probably wouldn't have taken the offer."

She further shared that she'd made the decision after receiving the offer in about 3-4 hours, stating, "When I was in my 20s, I was very prideful. I would often waste a lot of my time. However, things are different now, and I thought of just plunging into whatever was given to me. Whether it be a small or a big role."

She added, "We filmed for about half a day, and the episode was aired the next day."
