The video begins in a different dance studio as Chaeyeon and Wonyoung walk in front of the camera, Wonyoung's arms casually wrapped around Chaeyeon's shoulders.

| JUNG CHAEYEON
Annyeonghasaeo! Welcome to YSND TV! I am MC Jung Chaeyeon and member of YSND!

She starts clapping for herself and Wonyoung lets go to join her. Faint clapping and cheering is picked up in the back.

| JUNG CHAEYEON
Let's introduce one of the members joining us today. (hands Wonyoung and invisible microphone)

| LEE WONYOUNG 
(bows) Annyeonghasaeo, I'm your energetic girl, Lee Wonyoung! (points and winks at the camera)

Chaeyeon gives Wonyoung an applause as another girl walks in, Sua.

| JUNG CHAEYEON
Here's another member! Introduce yourself.

Wonyoung looks at Sua and Chaeyeon gives Sua the invisible microphone, catching Sua of gaurd for a moment but plays along.

| NOH SUA
Annyeonghasaeo, Noh Sua-ibnida~ (waves to the camera)

Chaeyeon and Wonyoung give another applause and Wonyoung steps back from the camera, looking off screen, calling someone over. Misun hurriedly walks in front of the camera holding Yumi's hand who's walking behind her. Chaeyeon, Wonyoung and Sua makes room for Misun and Yumi to stand in the center.

| JUNG CHAEYEON
Introduce yourselves (hands them the invisible microphone)

| PARK MISUN
(bows) Annyeonghasaeo, Park Misun-ibnida!

| LEE YUMI
Lee Yumi-ibnida~

Both girls wave to the camera and Wonyoung wraps her arms around Misun's shoulders from behind, who is shorter than Wonyoung who smiles

| JUNG CHAEYEON
Let's get started! (Points to the camera)

Everyone cheers and claps, hyping Chaeyeon up before falling silent and looking at eachother.

| LEE WONYOUNG
(laughing) What are we starting?

| JUNG CHAEYEON
The dances we practiced, yeah?

| NOH SUA
Ahh... which one should we start with?

| PARK MISUN

All the girls nod in agreement and Yumi goes to the stereo to start the song as everyone else got in their positions.

The girls laugh it off and start talking about the next song.

| JUNG CHAEYEON
Yumi and I have something prepared.

| LEE WONYOUNG

The girls all look at Misun who's waiting for them to laugh, but no one did. Misun lowers her head in shame with a small smile, trying not to laugh at herself.

| LEE WONYOUNG
Poor Misun-ah... (pets her head)

| NOH SUA

| LEE YUMI
Ooh, show us.

Yumi and Misun jump in at the end of choreo and begin to improv. Yumi's moves are more fluid while Misun is struggles to come up with dance moves, eventually giving up to watch Yumi.

| JUNG CHAEYEON
I think we used up all our time already.

| LEE WONYOUNG
Aww, so soon? (pout and rests her head on Yumi's shoulder.)

| LEE YUMI
Let's say goodbye then.

All five girls stand in a line in the center of the practice room and look at eachother, wondering how they'll say goodbye. Sua gestures to Chaeyeon to say something.

| JUNG CHAEYEON
Thank you for watching and support YSND as you wait for our debut!

| LEE YUMI
We hope we don't keep you waiting for too long.

| PARK MISUN
(teasing) Until then, Let's Debut!

| NOH SUA
Hey! Don't mock us!

| JUNG CHAEYEON
Bye!

Everyone waves to the camera, saying goodbye while Wonyoung playfully hits Misun's shoulders for teasing them.
