Brother! Vettel x Reader (Mihael x Reader)

This book will be based off of the song 'Servant of Evil' of Kagemine Len. The lyrics are not exact!! I tried my best!!

The song, 'Daughter of Evil' was a song everyone knew no matter where they were born, lived, no matter what gender, no matter age, no matter poor or wealthy.
The song took place in Kingdom of Lucifenia (now Carmon Kingdom). There once was a queen that was evil. Killing someone to have the one she loved. Using her servant that looked quite like her. Selfish, was the word they used to describe her. She got everything she wanted.
But that's a song created by people who didn't know the truth. The servant was once the one to become the King, but were separated and became a servant many years later for his twin.
The story of the unfortunate twins were only told to two families. Well to two people to be exact. How do they know the truth?
By a song. Where'd they learn the song? They don't know, it was a song they've known since they were babies, but the song does not exist.
What happens if the twins meet again after many centuries later? Will they have a happy ending? Will they end up with the one they love?
