About My Girlfriend Being the Boss of a Liquor Company

Blurb:

Amuro Toru, code name Bourbon, is the organization's hardest worker, spending his days bouncing between missions and the coffee shop.

For the sake of an investigation, he winds up dating his target by a twist of fate.

His girlfriend is the boss of the Karasuma conglomerate: rich, beautiful, and pursued by enough people to circle Tokyo three times. She is the archetypal overbearing heiress who gets everything her way.

Amuro Toru has the perfect plan:

Confirm she is harmless → act cold and distant → break up amicably.

After all, this heiress is probably only playing around because she likes his handsome face.

During their relationship, he discovers that his girlfriend is unexpectedly useful.

The organization's problems mysteriously dwindle, activity funds get approved with remarkable ease, and even when he tells Gin that his girlfriend is late, leaves early, and doesn't answer his messages, Gin only glares at him with a far more murderous look than usual and warns him not to let it happen again.

But once the mission is over, Amuro decides he can't drag a law-abiding citizen down with him, so he seizes the chance to break up with her.

She doesn't simply glance at him, casually agree, and grab her things to leave as he expected. Instead, she asks why.

Thinking of how much the organization values the Karasuma conglomerate, Amuro wants Karasuma Tsukimi to stay alert. So he turns the blame around and claims that the incidents they've encountered happened because she was being targeted, and that he wants to break up because he doesn't want to get caught up in it again.

After hearing him out, Karasuma Tsukimi's expression turns a little strange.

Then she agrees.

Ever since her father died, Karasuma Tsukimi has become the new Karasuma Renya.

Because of her unusual circumstances, her father had built a large research organization centered around her. Now her condition has finally stabilized completely, but her father is gone.

The research organization has grown a little too powerful, and Karasuma Tsukimi has to consider what to do with it.

According to Gin, her boyfriend is a member of the organization. Is Rum afraid she'll decide to abandon the organization, so he sent someone to whisper in her ear?

...No.

He's clearly trying to make her abandon the organization!

So here's the question: should she listen to what he's whispering in her ear or not?

After breaking up with Karasuma Tsukimi, Amuro Toru resolves that, if he can help it, he'll never use a honey trap again. From now on, he'll close off his heart and devote everything to destroying the organization!

Until one day, Conan tells him that the name behind the organization, deduced from his investigation, is Karasuma Renya.

Oh, the Karasuma conglomerate. That makes sense, only the Karasuma conglomerate could afford to bankroll the organization... Wait?

Amuro Toru is horrified. Hold on, who was my ex-girlfriend?!

Meanwhile, a dangerous question is circulating among the organization's senior members:

"The boss has been spacing out lately, and even asked us, 'If I quit for good, would you come with me?'

Who exactly is whispering in the boss's ear?!"
