The promise

"Oh No! This place was famous for their pianist I really want for you all to enjoy the experience. Especially you (Y/N), I thought this place would be nice for you" The old man said disappointedly.

Jotaro-"It's alright, Jiji it's not that important anyways." 

Polnareff-"It's alright. Although I was looking forward to it."

Kakyoin-"Polnareff! Stop being ungrateful!"

Polnareff-"what? You all wanted to see it to, you can deny it!"

light bulb appeared.

(Y/N)-"It's alright guy! I know someone who can play way better than the guy who was supposed to play tonight!"

Joseph-"Really! Who?"

I cracked my knuckles, and was walking to the stage was where the manager was about leave. With my music book. I ran and quickly called for him. "What do you want kid?"

"You said the pianist for tonight isn't coming right? Well, can I play, I promise I'm really good with any instrument." I asked him. He looked unsure about me and with a little more convincing he agreed. "Fine kid and if the crowd loves you I'll throw in a free desserts on the house along for you and your party." He smirked and went on the mic again.

"Alright everyone! Looks like things have taken a change and we actually have a volunteer to play tonight! Everyone please give it up for- what's your name kid?"

"(Y/N)"

"Please give it up for (Y/N)!"

As I went up to the stage I saw everyone in the whole restaurant clap and whistle to me. All eye's were on me especially the guys. Their cheers were the loudest one's. I sat on the chair and crack my knuckles once again to prepare myself. Got the mic close to my lips. This was my first live performance. You bet your ass I was nervous but if their here then I have no choice but to play for them.

(Y/N) playing this song but voice and piano only)

                  I will survive
                            ...
                 I will survive
                            ...
                 I will survive
                            ...

When I was done playing the restaurant freaking mob clapped me and yelling everywhere. I never had so many people liked my music so much. I got up from my chair to the middle and bowed my head. When I looked at the guys at the table they were yelling my name and clapping and I think I even saw the old man cry a little. Even Jotaro had a happy face on.

Seeing them happy for me made me happy. I made a ghostly smile at them. They were shocked and smile even more.

At least it's something.

The manager came back and shake my hand. "That was even better than I imagined! Congratulations (Y/N) you got the free desserts and you know what? Order whatever you want because everything is on the house. You saved the performance tonight and you deserved it." He gave me a smile and went on the mic again.

"Give another round of applause for (Y/N) everyone!"

Everyone was clapping even louder than before. I was about to leave when the band from before stopped me. "Hey kid.  You were super amazing up there! We were wondering if you want to play with us? Just one more song."
