You are lost in the forest, and come across a mysterious creature who has the upper half of a human and the other half covered by petals

Calla stares at you with sharp eyes and a strange smile. Quickly, his strange jet-black hands reach out towards you, and in the blink of an eye, sharp petals sprout from his hands and shower onto you, touching your skin and surrounding you

"Those who cross the forbidden boundary, shall find no escape, no mercy, and no happily ever after"
