Does anyone know of any anime that is similar to Kuroshitsuji book of circus?

Pandora hearts? It’s servant and butler. But like idk

There was this one that gave me the same vibes as kuroshitsuji....i cant remember the name. About a girl (i think she was from an esteemed family) and she falls in live with a guy who has long fingers and plays the paino well. Turns out hez a vamp.. and the ending had me shook
