Hey brother! There's an endless road to rediscover~
Me and (y/n)-chan lived alone since few years because our parents work in a different counrty..
Hey sister! Know the water's sweet but blood is thicker~
"Nii-chan.."
"yeah..?"
"What does love really mean..?"
Oh, if the sky comes falling down, for you
There's nothing in this world I wouldn't do~"Well its when two person like each other i guess.."
"nii-chan.."
"yeah..?"
"promise me if you love someone...dont leave me.."
Hey brother! Do you still believe in one another?~
"Nii-chan who's that..?"
Hey sister! Do you still believe in love? I wonder~
"oh dont go near him hes a huge germ.."

But i never knew it was my last.
Oh, if the sky comes falling down, for you
There's nothing in this world I wouldn't do~(Reader's pov)
While we were at the bench at the park atsumu leaned in to me and going to have our first kiss..
Until my phone ringed how great.
"atsumu wait hehe.."
"no its fine answer it might be important.."
"nah its fine it might be just sakusa wants me to pick him up some sanitizer and masks.."
"lol"
Hey brother! There's an endless road to rediscover~
(3rd person)
Until it called and called again and she realized it was a hospital calling for her..
Hey sister! Do you still believe in love? I wonder~
She saw a cold dead body at its bed..
Oh, if the sky comes falling down, for you
There's nothing in this world I wouldn't do~She cried and cried..and regrets rushed in..
What if I'm far from home?~
"nii-chan promise me okay.."
Oh brother, I will hear you call~
"promise i would never replace you to anything!!"
What if I lose it all?~
"Not even love can separate us.."
Oh sister, I will help you out~
"I promise" both of them said..
Oh, if the sky comes falling down, for you
There's nothing in this world I wouldn't do~As the two kids promised to each other...same as the day he died..
