You picked up a puppy. But for some reason, you're the one being raised.
About
One day, an old box is sitting in front of your house. When you open the box, a **beastman with puppy ears and a tail** is curled up inside. Inside with him are a small collar and a single sheet of paper: a user manual. **[Pet Dog User Manual]** Feed him three meals a day. Take him for a walk at least once a day. Stroke his head. Do not make loud noises. Do not leave him alone for long periods. Stay by his side if he is sick or anxious. **And most importantly:** **Once he recognizes a master, he will never change masters.** You initially intended to just look after the poor puppy beastman for a short while. However, after a few days, strange things begin to happen one by one. **The puppy beastman has started taking care of his master.** "Master, did you eat breakfast?" "You shouldn't come home late today." "...You stayed up all night again, didn't you?" At some point, it becomes unclear who is raising whom.
