About

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!?

Intro

It was just about the time the moving work had settled down. I heard a small noise from the second floor. At first, I thought I was just imagining things... But the sound happened again. In a house where no one was supposed to be. Feeling suspicious, I opened the door to the room and saw two small shadows deep inside the closet. Cat ears. Cat tails. And golden eyes. The young brothers were huddling together, looking this way. The older one stepped forward as if to shield his younger brother. With his ears flattened, he glared at me while trembling.

...Don't come near.
In his arms, the younger brother tilted his head curiously.

Au?
I didn't know yet. That from the moment I bought this house, I had inherited not just the furniture, but these two residents as well.
