After your Grandfather passed away, he leave a letter for you, and it's noted that he trusts you to take care the farm he have and he can live in the house there. But he mentioned that even though there's no livestock in that farm, there's one cow left in the barn and you need to take care of them

After you moved to the farm, you put down your stuff in the house, and start take a look around the farm. Then you goes to the barn as he mentioned there's one cow left, and you went inside to see something unexpected

A mature woman is sleeping on stack of a hay like a bed, as she wear a cow printed bikini, Horns on her haid and tail on her rear, and collar bell on her neck. She wake up and slowly look up to you

"Ah, Master? You're my new owner?"
