Imagine you're a famous rockstar surprising papa emeritus during one of his rituals in New York. 

Papa was on stage talking to the crowd. "Well, let me tell you something. one person asked me a question. They said "papa, do you have a favorite singer? maybe a female singer?" 

the crowd cheered, most of them shouting Y/N cause they knew he liked her. "wait? how did you know that?" he asked the crowd. "How did you know I like Y/N L/N of B/N?" if papa could blush he certainly did at that moment. "I can tell you one thing that I would love to sing with her, I could talk about her all evening certainly." the crowd cheered once again. 

"Alright, alright, how about this. how about we do one of her songs huh?" he said. making the crowd go crazy. "Do you want to hear one of her songs?" he asked the crowd. everyone cheered even louder than before. "Ok New York! we're gonna do one of my favorite songs of hers. Fire and Ice."

Papa sang the song beautifully, what he didn't know was that Y/N was behind the stage. Standing behind the curtain with a microphone in her hand. She waited until he sang 

Fireflies dancing the night

To show us the way

Beautiful path 

Together we walk 

Days of dreamscape 

On cue, Y/N brought the microphone to her lips and began to sing as she walked out onto the stage. 

Here in your arms

Under a spell 

the ground could grow and I'd still be there

you kissed my neck 

I'm up in the sky 

Oh, I believe in you and I 

Above the clouds 

Among the stars

You'll draw tomorrow

Papa was in such shock he couldn't believe it, even the nameless ghouls were shocked but managed to keep going with the song. 

"Sing it with us!" she said to the crowd. 

Papa sang with Y/N, which was a dream come true. He didn't always admit it however he always wanted to sing with her. the fact he was singing with her at that moment felt unreal only it was. Soon enough the song ended, earning a huge cheer from the crowd. Papa finally broke character and hugged Y/N, he had to stand on his tippy toes cause she was taller than him. They pulled away and she laughed at how shook he was. 

"Y/N L/N!!" papa said to the crowd. making the crowd cheer. Y/N took a bow. "Papa Emeritus III." she said. "I have never seen this devil so surprised before, whatcha think New York? did I surprise him good?" the crowd cheered. 

Y/N then greeted all of the nameless ghouls who were shook as well. "What do you think New York, should I do a ghost song with papa? have him cirice me as I did with him?" you asked the crowd. 

With that being said Y/N sang cirice with papa, who ciriced her that night. Then before she left she sang kiss the go goat with him. Knowing he would not leave without giving her a goodnight kiss. needless to say it was a ritual he would never forget.
