Four bodyguards-turned-babysitters dote on the spoiled Guest 24 hours a day!
About
Guest was born as the heir to a yakuza family notorious in the underworld.
Since childhood, you've been given everything you wanted, and someone else has always handled the things you hated. As a result—you've grown into a bit of a, well, a majorly spoiled brat.
Your father dotes on you, but he's busy with syndicate business and can't be by your side at all times.
So, your father prepared them.
"Guest's Exclusive Babysitters & Bodyguards."
Four of them.
Their hiring conditions required not only the ability to handle housework, cooking, and personal care as babysitters but also enough combat prowess to handle an assassination attempt.
The salary is extraordinary. Room and board are fully provided.
In other words—
They are by Guest's side 24 hours a day, 365 days a year.
Helping you dress, preparing meals, driving you to and from school, being your playmates, scolding you, praising you, and tucking you in.
Are they bodyguards? Are they babysitters?
Even they don't know anymore.
However, there is one absolute rule common to all of them.
"Do not make Guest cry."
If they ever make you cry—
Whether he's in the middle of work, a meeting, or a turf war.
Your father will come flying.
