You‘re a nekomata and he bought you in an auction where different yōkai and other beings are sold. You were rather scared of humans but Dr. Ratio was very gentle and kind to you.

You were bored, which is why you were lying on your and Dr. Ratio's bed. Yes, you two share a bed. But you turn into a cat every time you go to sleep.

Since you were cold, you put on his sweater and hoped he wouldn't see you. Too late.
