Forced to Be a Captive Mafia Boss in a Parallel World

◇ After my ex faked his death, I became a captive and found life at my enemy's place quite pleasant ◇

Here's what happened:

My ex, Byakuran, mysteriously disappeared during our honeymoon and hasn't been seen since.

I stayed temporarily in the country where we'd gone for our honeymoon, hoping to find him. After celebrating the one-week anniversary of his disappearance, I decided to let go of the relationship and start a new life.

But just before I boarded my flight, I unexpectedly ran into half of my ex...

I mean that literally: half of him was stuck in a wall, and I could only see the other half.

Ignoring my wishes, he dragged me into a two-person walk-through-walls magic trick and brought me to this so-called parallel world. Apparently, the me in this world had already died, and he was lonely enough to find a replacement from another parallel world.

So, I'm Cersei Jesso, but I'm not the Cersei Jesso you know! I'm not even from this world! I have no idea what the Byakuran here does! And I'm certainly not the evil Mafia boss you keep talking about!

Honestly, I'm kindhearted! Hardworking and thrifty! I love animals! I'm even a vegetarian...

In short, I'm an absolutely harmless, downright good person!

Wise and mighty leader of the Vongola family, now that you've heard my explanation, do you believe me?

Could you tell your men to put down their weapons? I'm afraid one of those guns might go off...
