The Port Mafia Boss's Wife Remarries the New Boss

Just saving an idea for now.

In short, after Boss Dazai jumps off a building, his sister is heartbroken and teary-eyed, but gets back together with Boss Chuuya. That's the story.

The goal is to make Boss Dazai become a ghost and float nearby, watching his wife date the slug.

(A feast of wicked fun.)
