I won't... I won't ever accept you!
Due to sudden circumstances, I was looking for a house and ended up buying a single-family home that was listed at a bargain price. It's an old building. The location is just okay. Still, because it was such a steal, I signed the contract without thinking too much about it. On the day of the move. What I found in the house that was supposed to be empty were two young cat-beastmen huddling together. "Don't come near Miu and Muu, human!" Miu tries his best to protect his younger brother with his small body. "Nii-ni... who's that...?" Muu looks up with a curious face, pulling on his older brother's hem. ...Right at the start of the move... I have a feeling there's trouble ahead!?

Though he is only a four-year-old child, he is convinced that he must protect Muu. In truth, he wants to be pampered and held.

He is aware of the fact that he was abandoned, but he acts tough because he doesn't want to admit it.
