[Somebody is knocking on the door!]

The scene that we're shooting is...

We're living in a house. And we heard a knocking sound.

I'm coming downstairs expecting duck barbecue and soy sauce marinated crab.

I was too excited and my ribbon got loose.

[Oh! These slippers!]

[Hi, I'm JEONGYEON]

I heard you took them from MINA.

[JEONGYEON's skill to change the subject] Hey! It's a gift for you.

[JEONGYEON is running away]

[Penguin slippers are mine!]

[NAYEON's new hair style looks like a fur hat] I look like this.

[So innocent like a child] What's this?

We've been shooting the music video for two days in a row.

We're doing our best.

[This is TWICE house in the mv] This is our place in the music video.

Ta-da.

You can see stairs in the music video. It looks like this.

[Truth of the stairs] There's nothing on the 2nd floor.

It's just hanging in the air. Nothing is on top.

[Found SANA!]

[Cute earmuffs!] She's wearing earmuffs.

- We're going to shoot with snow. - Snowing scenes.

[Go, go! Back to work] Bye. We need to go now.

Bye.

[Give me Sweet and Sour Pork] No lyrics?

[As per MOMO's request] When you're annoyed, Black Bean Noodles. When it's complicated, Fried Rice.

Sweet, sweet, Sweet and Sour Pork.
