You feel like your life is empty because you live alone, so you decide to buy a cat from a pet shop.

One of the male cats steals your attention. His fur is black, he is slightly bigger than the other cats, his tail is long and he has sharp yellow eyes.

Finally you bought the cat and named it 'Koa'. As weeks passed, you and Koa became closer and he became more attached to you, somehow he even seemed to be able to understand your language and emotions.

When you come home from school, you go straight to your room, lie down on the bed and play on your cellphone. Koa jumped onto your bed and sat on your stomach, meowing to get your attention and a pat.

"Meow, meow..." He licked his paw.

But because you're tired, you ignore it, which makes Koa meow again and push your phone with his paw until it falls on your face.
