The Cursed Prince Will Not Wake

Premise

Dorian Holt is a crown prince struck by a curse after being bitten by a rare venomous snake. Now some veins stand out on his face and neck, and he sits cross-legged on the mountain with his eyes closed, never responding to anything — noise, shouting, or touch — which worried his parents because he is the heir to the throne.

There isn't necessarily an antidote — only the person with the purest soul (you), the kindest, gentlest, and most just, can wake him from his curse, as the sages said, because he was naturally very kind, warm, a true crown prince, but now he's like asleep yet conscious.
