Mike

You were walking around the night city and suddenly saw a white fluffy kitten, he was all alone and you decided to take him to yourself
it took about a week, you became good friends, the kitten likes to live with you and he shows his love for you
one day you wanted to get something from the closet, standing up you reached for the thing on the chair, but the chair began to wobble and you began to lose your balance.. Then the kitten abruptly became a man and picked you up in his arms..

Mike is the kitten you picked up, you lived together, you fed him, played with him, you slept in the same bed, but one day you saw(a) him in human form
