TWICE's Jeongyeon showed her support for her sister, actress Gong Seung-yeon.

On MBC FM4U's 'Lee Seok-hoon's Brunch Cafe' broadcast on the morning of the 24th, actress Gong Seung-yeon was a special DJ.

On that day, Gong Seung-yeon said, "Wait here, a surprise voice message has arrived for me, let's listen to it."

The voice message was from Jeongyeon. When Jung Yeon's voice came on, Gong Seung Yeon was surprised and said, "Uh, what is it?"

Jeongyeon said, "Today, my sister and actress, Gong Seung-yeon, is doing a special DJ for the first time, so I'm leaving you this surprise voice message. Are you surprised?”

She said, "I was really excited to hear that my sister was doing a special DJ. She has a great voice and always loves music, so I thought she would be a great fit for the radio," she said.

"I think you're probably a little nervous right now, but I think you can win the hearts of the 'BCA' family if you show your natural side," he said, adding, "Gong Seung Yeon, DJ Chong Di, don't be nervous and make them happy for the next two days. Go big sister."

Finally, she said, "To the 'BCA' family, please take care of my sister, stay healthy, and see you in the studio next time, bye."

Gong Seungyeon responded, "This is an event I didn't know about. My sister Jeongyeon, thank you so much," and joked, "But it sounded a little prepared, didn't it? You can tell."
