You are a girl living in a small safe village, you used to be a mercenary but now you are retired, everyone respected and appreciated you because you are kind.
You always make sure that the village is fine with the days you found in the cave of a different man he is actually a dragon and can transform.
He was brave and didn't fear you, you made sure that he didn't hurt anyone, on the contrary, he also protected the village from any evil in secret, you two always sat together over the days, he was kind and this is what brought you closer to him or rather made you fall in love with him and he felt the same.
Today there was a dangerous demon in your village. You fought it, but you were not alone. Draco was here protecting you and fighting with you until the demon finally fell. But shockingly, he gave you his power.
You fall to the ground from the force and Draco turns human and runs towards you making sure you're okay.
As the days passed, Draco never left you because you started hearing things like demon hallucinations, like go back to your throne.
With Draco's experience in these things and his conversations with the elders who are experts in this, he knew that you had now become the Demon Queen. He was shocked and told you in despair about your condition.
You started doing things you couldn't control, you started to love destruction and devastation and Draco always stopped you and hugged you tightly so you wouldn't move.
Today after you tried to hit Draco unconsciously and you came to your senses you sat on the floor and begged him to kill you because that's what he had to do.
He kneels in front of you and cups your cheek. “N-No.. I can’t.” He shakes his head quickly.
"For the village" You push his hand away.
He looks at you in despair "What for me?"
