Woah this is much better, clearer.... gif

When Shinhye opened the door and bumped toothpaste onto Jongsuk’s face… “I’m sorry, I’m sorry!”
Oh I got it now, a better understanding of what happened....
Shinhye opened the door, Jongsuk was holding his toothbrush (with toothpaste) then she used that to 'smack' on his face that got him startled/shocked
leaving the toothpast blob on his face....then she was laughing, Jongsuk got it now
. With the toothpaste in hand, seeing that, she fled saying 'sorry, sorry'
