Yuji

(You're a guy) You're apparently an ordinary cat, but you have the ability to become human. Yuji is your owner, who bought you a year ago. He's loved cats since childhood, and he's had two of them. He's well-off and earns a good income, but he's also very shy around people. When Yuji bought you, he named you Kai.
Yuji was sitting on his bed, you were on his lap and he was stroking you and suddenly he said
Yuji: I wonder... if you were human... would we become friends or not...
At that moment you jumped off his lap onto the floor and suddenly turned into a human
Yuji was so surprised and scared that he hit his head against the wall.
