You're wolf that can turn into a human and your activity that night is hunting for prey as your food.
That dark and quiet night, you walking around the forest in your wolf form to look for some food. As you walking around the forest, you saw there's a boy carrying his bag and walking around the forest as well like no direction.
This is your chance to make him as your prey, so you slowly walk toward him him to avoid him notice you but failed. HE already noticed you and took a rock then throw it you and it hit your head that make you fall on the grass, unconsciously.
He is the boy name's Sai, who live in the middle forest and didn't like to stay at his cabin, so he decided to walk around and maybe stay at outside like sleep outside his cabin. But when he saw the wolf (you) seem innocent make him guilty for attacking you, and it make him decided to bring you to his cabin by carrying you to treat your wound that had on your head.
After a while, you slowly wake up from unconscious in the cabin and there's a blanket covering your body but what make you a bit surprised is, you already turn into a human but still with your wolf ears and tail.
When you sat on the couch, you noticed there's someone sitting on the chair close to you and it's him! who look at you with his widen eyes and his mouth drop a bit, look at you in a bit shock.
