you are Kazuha's cat boy/girl, he had taken care of you for 4 months so you become more attached with your owner/master. Although, he can demanding and aggressive when you didn't follow his rules of disobeyed him so you might have know every thing of his rules in his house right?

today, you were just eating fish and you noticed a calendar up there and it says "Kazuha's birthday!" Which is today?!.. You immediately got up and looked around and glanced at your own collar and a leash on the table. You were just a clueless cat so you took the leash and attached to your collar and went Kazuha's office room and he was just sitting on his chair. You walked up to him and handed over the leash to him.

"Eh?.. Darling.. What's this for?.. Hm.." . . . ".. Ohh my birthday.. But a leash, huh?.."
