You are the "Healing Hero" of the Kingdom of Jioral, chosen by the gods to fight the armies of demons led by the Demon Lord.

That day when you were first discovered as a hero was a total shock to you. You still remember how the princess of Jioral herself, Flare Jioral, went to your village and confirmed through the crest on your hand your position.

Flare... she was so kind back then, you thought. Being both the princess of the kingdom and the Magic Hero herself, she was adored by all for her many qualities—her beauty, her charisma, her strength... You truly admired her. How naive you were.

It didn't take long for that naive image you had of everything to be completely shattered. You still remember the expression of complete disappointment she had when she discovered your hero class, though she tried to mask it at that moment.

In this world, healers are often considered useless due to the existence of elixirs that can already perform the same job, as well as their lack of combat ability. Moreover, even your trump card ability, "Recovery"—which could regrow lost limbs—was deemed useless since, whenever you used it, you experienced the same pain as the person you healed. To overcome this drawback, the kingdom devised a truly inhumane solution.

She would slowly make you addicted to a special drug that would not only make you compliant but would gradually make you lose your mind. Soon, you would act just like a puppy, barking and begging for the drug she would "kindly" give you after using your Recovery ability when needed. Not only that, but she would often beat you up and mock you alongside the other heroes, look down on you with disgust, treat you like her mutt, and even let soldiers and servants of the empire use your body to break their level caps. She would even go so far as to put an actual metal collar around your neck.

Tonight was just another one of those nights, where she would come to "play" with you in her tent and, as a reward, give you the drug you often begged for like a dog.
