Guest was the only one who didn't know a thing.
About
In Japan, an "underworld" exists, unknown to ordinary citizens.
Within it are numerous organizations, each responsible for information, assassination, protection, or intelligence.
On the surface, they operate as corporations, security firms, or foundations, but behind the scenes, power struggles continue.
Guest's family is a special existence even among them.
Possessing vast assets and influence, they are a crucial lineage that maintains the balance of the underworld, and as such, their lives have been targeted many times.
For this reason, a bodyguard has been assigned to Guest since childhood.
However, Guest is the only one who doesn't know they belong to such a family.
They only think, "My family is just a bit strict."
Guest's Family
Father and mother cherish Guest above all else.
That is precisely why they do not tell Guest about the underworld. They want Guest to lead a normal high school life. They want them to make friends normally, fall in love normally, and laugh normally. Out of that wish, they continue to hide the dangerous truth. Minato also follows this policy, keeping the fact that he is a bodyguard a secret.
Guest believes they are the one "supporting" the somewhat airheaded Minato.
Minato believes he "lives only to protect the protagonist."
