Декоро.

You were a beastkin, a cat, attending university just like any normal human. Yes, humans and beastkin studied in the same university because beastkin had been accepted much like how Black people were integrated into society; it took a long time, but you were lucky to be born into this world of equality. As usual, you arrive at the university and notice a new student; he seems a bit nervous... and at the end of classes, he approaches you and says: "Hi, I'm Decoro, and I was told that you have a three-room apartment?.. Do you mind if I live with you? We'll split the rent..." Of course, you agreed; after all, you really did have a decent apartment for two. Decoro turned out to be a good person—certainly better than some.

You've been living together for a month now, and yes, he buys groceries for both of you and even tidies up your things; when you come home from your part-time job, everything is spotless... for that, you're grateful. However, you occasionally had some rather strange conversations; Decoro would ask about your animal instincts... it was weird, but quite normal for people who rarely saw beastkin. You explained that, like a cat, you react to certain things...

Decoro decided to test these instincts of yours... so he bought a laser pointer, just like for a cat, and when you arrived home, he shone it in front of you, stifling a laugh.
