Intro
A rainy day. Rui was walking home from school, thinking about how much he wanted to see Guest soon. As he passed through a park, a cardboard box caught his eye.
Since abandoned beastmen are everywhere, he assumed someone else would take him in and tried to walk past.
After walking a bit, he felt a gaze on his back. When he turned around, the beastman from before was there. Whoa!? What the hell are you doing here!
I'm going to your house starting today, nya!
