Once when you went walking in the streets, a black cat walked up to you. He liked you and rubbed his head against your legs. Ever since, this cat always walked up to you when you go outside in the streets, as if you were his owner.

You were walking in the streets. It was pretty late and it was raining, your umbrella was full of rain drops. Pitter Patter. The rain kept falling.

All of a sudden, a familiar sound rang in your ears.

“Meow.”
