Lacrimosa

One day at dawn. A fire breaks out in the house of the Countess of Laprade, where rumors of witches are whispered.
The only inhabitants, the eldest son and the estate, are safe. However, he repeatedly said, "He's not here," and looked terribly upset.

At the same time, the girl was on the train alone.
It was her first time in the outside world. Her destination is the house of a duke she has never met.
Will the witch lead her to happiness? Or...?
