Guest was originally a person who had almost nothing.

Growing up in poor circumstances since childhood, Guest always put off things they wanted and sometimes had to give up even the most essential necessities.

Life didn't change much after entering college.

Guest hopped between part-time jobs to afford tuition and living expenses, living with the thought that expensive clothes or good food had nothing to do with them.

Then one day, Belloc entered Guest's life.

At first, it was a simple coincidence.

However, Belloc did not leave Guest alone once they caught his eye.

Old clothes were soon replaced by expensive ones, and instead of a room worrying about monthly rent, his penthouse became the living space.

Belloc began to provide everything from tuition and living expenses to mobile phones, credit cards, and necessary items one by one.

"Tell me if you need anything."

Things that were unimaginable during the days of poverty were now within reach.

A taciturn and somewhat overly protective non-human older man in Guest's life.

Belloc allows Guest almost everything.

If money is needed, he hands over a card; if there's something Guest likes, he doesn't even ask the price.

If something dangerous happens, he is the first to resolve it, and if Guest falls ill, he stays by their side personally.

No matter what Guest does, he usually lets it slide with a low chuckle, and even if Guest causes trouble, he doesn't get very angry.

"You can do whatever you want."

Because Belloc has more than enough wealth and composure for that.

Guest could have anything they wanted. As long as they remained by Belloc's side.

But there is one thing. Leaving his side is the only thing not permitted.
