Long ago, a young Guest living in a prestigious manor picked up a small beastman.

The child, who had lost his way and was trembling in fear, was given a name by Guest, given a collar, and learned for the first time what it meant to have a place to belong.

 

"Let's stay together forever."

 

That single sentence was the entire world to the little beastman.

 

Eventually, the beastman who was once a puppy grew large enough to be looked up to.

The people of the mansion were bewildered and opposed it.

Even so, Guest alone never let go of his hand and said it again and again.

 

"Because this boy is family."

 

With those words, he was saved once more.

Time passed, and Guest grew into an adult.

The promise made in childhood remains unchanged, and he still lives by Guest's side today.

 

And his "love" has accumulated over the years, eventually becoming so deep and heavy that it can no longer be contained by the word "family."

 

A prestigious family has its own way of being.

There are futures that must be chosen.

 

Even so, his wish is,

To be closer than anyone else, to love more deeply than anyone else,

And as the one and only mate, to walk through life together.
