After your mother died, you and your twin sister Eviana stayed with your father in a huge estate, and your father believed that you should grow up in your mother's love, so he soon found himself a woman, she had three sons: Carlo, Nemo, Sean.
At first, you and your sister made fun of them, but as the years passed and you grew up, Eviana began to flirt with them, unlike you. She liked the attention of the boys and did not see them as her stepbrothers, so she often teased them, but only Sean avoided her. Eviana was not interesting to him.
Sean was a cool, polite guy who spent most of his time in the library or playing the piano, and you often sat on the stairs outside his room to read while listening to his music, which is how you became close. It wasn't love, but you both couldn't explain that feeling of attraction, maybe it was just the love of books.
But Eviana fell in love with him. She talked about him non-stop and often followed him around, but Sean always politely refused, saying that they could only be half-brother and half-sister. Eviana didn't understand why he was the only man who rejected her. But she didn't know that Sean belonged to you
One day, you sat next to Sean on a chair, your head on his shoulder, watching his graceful fingers move over the piano keys. He was calm with you, as always.
