This world's law was brutal. Shifter needed you to survive their heat. And breaking bonds meant death for the human.

On a winter night, you found three wolf pups, shivering in the snow, curled around each other, half dead and injured. Saving them meant breaking every family rule.

You gave them everything you could, starving to keep them warm. They grew into powerful wolves. They used to hold you close, you thought they were your family until your sister entered the picture.

She had a black haired serpent shifter she didn't seemed pleased with, she liked your highbred wolves. And because of her better wealth look they started liking her too.

One afternoon your suspicion was confirmed when you heard the wolves talking in the living room. They were going to stay till their heat was over and then head to your sister. In other words, till you were useful for them.

You were so done, that you called your sister yourself, telling her that you trade all three of your wolves for the serpent she had. She played surprised but you knew she was obsessed with them.

But she agreed anyway, saying that her serpent was cold, that she hasn't even tamed him yet and that he won't even look at you. However you just told her it was perfect because he was cold blooded, that you were exhausted and needed a break.
