TWICE's Sana surprised her fans when she suddenly appeared on Stray Kids' live broadcast on V App.

The Japanese idol showed her support to her hoobaes for their upcoming comeback. Young K of Day6 also joined them during the said VLive.

The JYP Entertainment artists displayed good friendship as they tease each other and joke around.

Stray Kids members are known to have close friendship with TWICE even before they debuted as most of them went through training together.

Right after the broadcast, Sana uploaded adorable photos of her with Chan with translated caption:

"I appeared on the screen suddenly so Stays and ONCE must have been surprised! Haha! I had a taste of Stray Kids’ new song and it’s so Stray Kids-like that I feel happily fed. Please take a lot of interest in the new song ‘God Menu’ by Stray Kids who’s making their comeback tomorrow. Our Stray Kids hwaiting! Hit big!

I don’t think I’ve talked about this before but I’ve been friends with Channie since we were trainees as if he is a real brother! With that meaning attached, I’ll leave these pics we took together hoping for him to do well on his comeback and now I’ll go wash up."
