Hahahahahahahahahahahhahahahahaha...

(Y/N) loved going to Mettaton's shows. Those had to be some of the coolest things Monsters brought with them to the Surface. They didn't like them for the stage performance or choreography, but for the music.

The ghost acting as DJ had to be one of the most talented musicians they had ever heard and the backup singer was far more talented than most popular human artists. If the two of them wanted to start a band on the side of Mettaton's performance, (Y/N) would likely pay whatever it took to have all their music.

Monsters they met at concerts seemed very happy to meet a human so accepting of them. Reception to an entire civilization that had been living underground and... killing human children for a long time was a bit mixed—for somewhat obvious reasons. It's not like anyone was pushing to start another war, they were just not the friendliest to them. Because of this, (Y/N) and any of their human friends they could convince to go were usually the only humans at the concerts, making (Y/N) extremely recognizable to all the Monsters that regularly attended them too.

"HI (Y/N)!" They nearly drop their car keys as a recognizable voice yells at them across the parking lot of the theater the show was being held in that night.

"Hi Undyne." They turn to the fish lady, "Are you and Alphys having a date tonight?"

"Yep!" Undyne catches her girlfriend in an affectionate headlock.

"I-It's only l-l-logical we s-support Mettaton after..." Alphys blushes fiercely as she reaches up and feels Undyne's strong, scaly arm of pure muscle, causing her to stutter a bit more than usual.

"Oh, that's fun." (Y/N) snickers. "I think the flier said today is a special show."

"Oh no." Alphys's partial smile drops to a nervous frown.

Undyne laughs, "Do you think it'll have bombs again Alphys?"

"I hope not...!"

"'A-Again'?" (Y/N) repeats nervously.

"Oh look, it's Papyrus!" Undyne suddenly runs off toward the parking lot entrance, Alphys under her arm, "SEE YA (Y/N)!"

"'Again'...!" (Y/N) says once more, hoping that Undyne was kidding.

The audience chattered excitedly before the show began. Clearly everyone was looking forward to whatever this special show was. Maybe (Y/N) was overthinking this. No one else seems worried about it.

"HELLO EVERYONE!" Mettaton's loud electronic voice is met with thunderous applause and cheers. "AS I'M CERTAIN ALL OF YOU KNOW, WE HAVE A VERY SPECIAL SHOW TONIGHT!!!" There's more applause. Then the music changes from the classic show music to the sad moment music, "MONSTERS HAVE HAD SUCH A HARD TIME GETTING HUMANS TO ACCEPT THEM... THAT IS WHY WE HAVE HAVING A VERY SPECIAL INTERVIEW WITH MY BIGGEST HUMAN FAN!!!" Mettaton claps as the spotlight shifts all the way to the back row where (Y/N) was sitting.

What? Uh, cool??? This is happening now... They awkwardly get to their feet and speed walk up to the stage. They wouldn't have sat in the back if they knew they were in the show tonight.

"WHAT IS YOUR NAME?" Mettaton offers them a microphone. They didn't know he had one since he never uses one, his voice is just so loud. It's almost deafening up close.

"Uh, hi." They take the mic from his hand, "I'm (Y/N)."

"WHAT A WONDERFUL NAME!!! EVERYONE, GIVE IT UP FOR (Y/N)!!!" He and the entire audience applaud.
