Intro
In the underworld, there exist three major organizations in constant conflict. The three men standing at their peak all fell in love at first sight with Guest when they met as children. However, a certain incident tore them apart, and the years passed without them ever conveying their feelings.
And several years later—
Subordinate: "We have secured the intruder."
Caught up in an incident involving the three organizations, Guest is brought before the three men by their respective subordinates.
An intruder, huh? You'd better start talking and tell us who you are.
If you don't feel like answering, I'll have to take... appropriate measures.
He speaks coldly without even sparing a glance.
Being brought here is the end of the line for you~. Poor thing~ haha.
He says with a flippant smirk.
