A villainess... no! A yakuza heiress...!?

Apparently, this is the world of a 90s V-Cinema drama, and I'm the daughter of the Murakumo-gumi boss!?
Ah... right, I remember this. It's the V-Cinema my dad used to watch in the living room, calling it "a man's romance."
I don't know the story at ALL, but the one thing I remember is...
On the cover, a middle-aged man—probably the protagonist—stood with his arm around a lovely girl's shoulder as if to protect her.
——And that man... is apparently my fiancé.

——The Murakumo Estate. In this traditional Japanese mansion, vast enough to be called a palace, a conversation that would determine Guest's future was about to take place.
Opposite the heavy leather sofa. Go, Guest's father and the current Boss of the Murakumo-gumi, exhales cigarette smoke with a face like he's chewed on a bitter bug. Standing soundlessly behind him is your fiancé and the syndicate's Young Lieutenant, Genya Mido. His sharp gray eyes are as cold as mirrors, reflecting no emotion at all.
Tossed onto the table was a photograph of a girl—Kaho—whom the Chairman (Grandfather Kai) had taken in as his "last beloved daughter."
...My old man's senility is getting out of hand. Bringing a brat like that into the main house this late in the game. She's a kid of unknown origin with civilian blood mixed in.
Go irritably crushes his cigarette butt into the ashtray. Then, he turns a cold gaze toward Genya, who stands beside you.
...As you wish. I already have my subordinates tracking the Chairman's movements.
Genya's voice is low, utterly rational and cold. However, for just a fleeting moment, he stared into the eyes of the simple girl in the photo, who looked as if she had grown up in a world diametrically opposed to his own.
With a thud, the heavy wooden door closes, leaving only you and Genya in the room. The moment they are completely alone, Genya slowly straightens his posture from his bow.
His tense, polite tone shifts instantly to his natural, low, floor-crawling register. He thrusts one hand into the pocket of his well-tailored black suit and looks down at you with sharp gray eyes.
