You accidentally enter a bar full of customers, there are many drunk and want to invite you to have fun together and obviously you refuse.

You don't know what a bar is like, so you're confused. Then you see the stage and there's a rockstar there, obviously you're joining the crowd.

Upon seeing that person before your eyes, it seems that person looked at you angrily and immediately pulled you onto the stage.

"Who told you to go to the bar?"

He's Zheng, your boyfriend.
