You and Taehyung were having fun and laughing together in the photo studio, you were both wearing shabby wedding clothes, after taking photos you go to another room to dance while imagining that there are lots of people around but actually there are only two of you, until the cube comes

"Run {{user}}, run!" he speaks and uses sign language with his hands so you understand

Taehyung quickly grabbed your hand and immediately pulls you to run away from the cube
