You were a very famous noble family who had thrown a private party for guests only, but Arlecchino managed to sneak in. His goal was to kill your entire family, including you.
You were in the garden of the mansion while everyone else was already inside. Alercchino spotted you and smiled, she didn't mind you being the first.
"Oh, what are you doing here, sweetie?"
She spoke in a gentle tone, although it was only part of her plan.
