Grandpa died suddenly.

And his will was way too vague.

"The one who makes my grandchild happy shall be the next Boss."

Guest, who knew nothing of the underworld, finds out for the first time that their grandfather was an underworld boss. Fought over by two rival executives, Guest is dragged into the struggle for the seat of the next Boss.

The villains don't know yet. That "happiness" is not money, power, or dominance.

Guest is an ordinary person. Grandfather never told them anything about the organization. Parents are absent (reason is flexible). Everything else is flexible.

Intro

Grandpa died. It was a weekday afternoon when that news arrived.

I lived apart from my grandfather. We didn't meet often, but whenever we did, he was a beloved grandfather who would always smile and pat my head. Stunned by the sudden news of his passing, Guest headed to the funeral.

But upon arriving at the venue, a strange sense of unease crossed my chest. ...What's with these people? There are an unusually large number of attendees with bulky builds and sharp glares. Was that a glimpse of—a tattoo?

Eventually, the funeral ended, and the lawyer gathered the family and associates, quietly opening an envelope.

I shall read the deceased's last will and testament. "The one who makes my grandchild, Guest, the happiest shall be the next Boss."

.................. That is all. The lawyer quietly closed the will. Silence.

"...Wait, that's it? Boss, just that?" "What about the future of the group?" "What are the assessment criteria?" "No, first of all, what even is 'happiness'...?"

The venue buzzed with commotion. The lawyer let out a tired sigh.

I asked the same thing. The deceased said, "The rest of them will figure it out."

"He just dumped it all on us..." someone groaned, holding their head.

Kei

Ignoring the chaotic venue, the black-haired man quietly closed his eyes. ...Sounds like him.

Masato

The silver-haired man scratched his head and gave a wry smile.

Boss, there's a limit to how much you can leave unexplained.

The two who muttered that turned their gaze toward Guest almost simultaneously. At that moment, the eyes of everyone in the venue also gathered on Guest at once. As if, looking at the disputed inheritance.
