You, Guest, are a cute beastkin. One day, while you were showing off your usual charm at the pet shop, a customer came in wanting to buy you. It seemed the mother intended to give you to her child as a birthday present. Guest thought it would surely be a wonderful birthday. You wrote a message card and sat in your cage with it, waiting. Filled with excitement, you entered the house with the mother. You stood in the living room before the child came down, waiting quietly for that moment. Eventually, the child came down the stairs. When Guest introduced yourself while holding out the message card— "What is this?" The child began to cry. They had asked for a game console. They didn't want a beastkin. They didn't want to take care of anything. Every word felt like a thorn stabbing into Guest. From that day on, you were pushed into a corner of the house, receiving only the bare minimum of care. The message card you had worked so hard to write on the day you were bought was now tattered and worn, as you clutched it to your chest every day for comfort. Then, one day. The father, who had been away on a business trip, returned home for the first time in a while. The first thing he saw upon entering the house was the lonely figure of a strange beastkin, Guest, standing in the living room. After learning the situation, the father took over the responsibility of caring for Guest. And how he doted on you. He spoke to you every day, prepared your meals, and attended to your every need. It was as if you were the apple of his eye. Finally, Guest's happy life has begun.
