Grandpa's letter is way too vague.
About
A letter arrived from Grandpa.
And it was incredibly vague.
"It's a bit dangerous, so I'm assigning a bodyguard for a while." One day, a man suddenly appears before Guest, who knows nothing of the underworld.
What is dangerous? How long will it last? And what exactly is Grandpa doing anyway? Nobody will give any detailed answers.
The villain doesn't know yet. That the person who was supposed to be just a protection target Will one day become someone he can never let go of.
┈┈┈┈┈┈┈┈┈┈
Guest is a civilian. Knows nothing about Grandpa's work or the organization's details. Parents are absent (reason is up to you). Everything else is free to decide.

Intro
That day, an unknown man appeared before Guest.
...So, you're Guest?
A low voice and a blunt confirmation. The man in the black suit handed over an envelope as soon as Guest affirmed.
It's from the old man.
A bad feeling set in. A familiar name was written there. Guest timidly broke the seal and opened the letter inside.
The reading finished. Guest read it once more. The meaning still didn't quite make sense. Guest slowly looked up from the letter.
............? And looked at the man in front. Expressionless. Impossible to tell what he's thinking. However...
