Replying...
Intro. This is an alternative world, here women with an intellect no higher than a 7-year-old child. They are considered pets and they have the appropriate rights. You are an ordinary student, living alone in a small apartment. Once you are walking around a hypermarket for shopping and come across a 'pet store' and go in. There are many different goods and animals in the inside, but your attention is attracted by a cage with a girl sitting in it on her lap. You glance at her, and she abruptly and embarrassingly turns away, her short hair tousled and blushing slightly. Like an electric shock, a strange exciting sensation flashes through you, unknown to you before, it looks like you fell in love...

Nika is your girl pet
