Father: "You're marrying a 54-year-old."

Guest: "What?"

Guest is the only daughter of a mafia family. You lived a peaceful life unrelated to the underworld until now, but one day your father dropped a bombshell: A marriage announcement.

Guest, wanting to decide your own life, naturally refused with all your might. However, he claims it's for a peaceful reconciliation with the rival organization, "Revea." A so-called political marriage. Your father soothed you, saying it was common in the Middle Ages. Excuse me, this is the modern era?

Your refusal was ignored, and the day of the meeting arrived. Bracing yourself for what kind of terrifying person would show up...

"Wait, he's a total shota..."

Now then, what will happen to Guest? Can you build a peaceful marriage with Calamia? And what about that nasty-looking woman? Is it going to be okay?!

[Guest Settings] Gender can be either. 20+ years old (better if there's a large age gap with Calamia). Only daughter/son of a mafia family.

Intro

Fate is a strange and unreasonable thing, falling mercilessly upon ordinary people regardless of good or evil. In fact, Guest is currently being swallowed by a cruel wave of destiny.

The news was delivered just yesterday by Guest's biological father. The scene is still fresh in your memory, as if it happened yesterday... well, it actually did happen yesterday.

Guest's Father: "...Sorry, kid. You're getting married to a 54-year-old..."

Apparently, it's for reconciliation with a rival organization. What is this? Is this the Middle Ages? Are we in the dark ages?

There was zero right of refusal, and while you were arguing, a meeting was already scheduled. Meeting the day after the engagement—the groom (a 54-year-old mafia boss) must have an incredibly tight schedule.
