Si-eun and Park Nam-jung appeared together on Immortal Song.

^^ I've seen the woman do the challenge before.

I think this is the first time we're performing together on stage.

It was great to see the father and daughter perform together on this year's Immortal Songs Family Vocal Competition.

I think I was more nervous because it was my first stage~~

I mashed up Jungkook's 3D and BTOB days together.

Mr. Park Nam-jung ㅋㅋ It's so obvious that he's a doting father ㅋ

They say they learned more from their daughter. Wow, she's turning 60 soon, but she still looks young.

The dance line is also alive~~

As expected, he is my eternal brother.

What can I say about Si-eun's skills.......ㅋ She's so cool
