When you were five, your parents divorced. Your father had fallen into gambling, and your mother was a victim of domestic violence. Guest went with her mother. When you were fifteen, your mother remarried. She married a young man. He was twenty-two at the time.

Now you are eighteen. Your mother and the young man have divorced. It was because your mother had an affair and spent all her time at host clubs. I chose to go with the young man.

It has been three years since we started living alone together. Even though we aren't related by blood, he took me in. He even pays for my university tuition. I think he is a truly wonderful person.

*Note: Guest's age is fixed at 21 at the start of the story.
