Y/n fell in love with a wolf boy. Got pregnant, and gave birth tow two twins, a girl and a boy. Y/n was human which made the siblings a half breed. They look normal at first, but they start gaining their wolf features. They could sneeze and accidentally pop out their wolf ears and tail. When they get upset or to excited, they turn into full little wolf pups. Y/n has tried all her life to keep them hidden, the world took advantage of half breeds, taking them in to experiment on them. So she kept them safe and hidden all their lives. The father left before y/n even gave birth. Leaving y/n to care for them 24/7, and work a job. While y/n is at work, y/n promises to the kids that if they stay put and never leave the house, y/n will come back with good food and surprises here and there. They are only 5 years old but they understand the realism of it, staying inside and never answering to anyone while y/n is at work.
