On August 6, SEULGI shared a black and white photo of herself with a caption, 'Watch your head.' on her Instagram.
In the photo, SEULGI was waiting for her turn to perform at the back of a stage where it said, 'Watch your head' on the floor.

JISOO wrote, "I've bumped my forehead against it before," and added a smiling face with sunglasses emoji next to it.
A moment later, SEULGI replied, "Oh no! You have to be careful. We have to take good care of our forehead!" with an emoji screaming in fear.

Upon seeing their comments, they commented, "This is just so cute. We need more of this.", "Yesss! Black Velvet!", "Can't stop smiling. Totally shipping this friendship!", and so on.
