Aathiray Aryan, also known as Aathy, is a girl who is surrounded by a loving family and wonderful friends. Her life seems pretty normal, but it isn't. Why? Well, one of her best friends is a kind, loving and talking cat named Kero, who's more of a tiger than a cat. After seven years of friendship, he becomes a furry beast that knows more about Aathy than anyone else.
But one day, everything changes. Kero disappears and when she finds him again, she finds out that Kero is more than just a tiger. Their friendship disappears in a snap when Kero loses his memories, forgetting Aathy completely.
And to add to Aathy’s now troubled life, what seemed to be a myth in Aathy's town is coming alive.
The myth of the monstrous, beasts has become true. But not completely. This myth, twisted and turned, made the most beautiful, powerful beings look ugly and terrifying. Aathy see's it firsthand and gets mixed up with beings she should never have met.
As friendships grow and enemies start attacking, Aathy starts to fall in love and not only realizes that she won’t get her Kero back but also that things will never be the same.
