My Ex-Boyfriend Is the Tenth Vongola Boss?!

[My upcoming novel, The Little Things About Helping Tsuna Replenish His Magic, is listed in my profile.]

Blurb:

Ten years ago, Amamiya Mari was an irredeemable bad girl.

She was spoiled, willful, arrogant... and, most importantly, she deceived a sincere fool.

She lied and told him she liked him and wanted to be with him, but it was all just a prank.

Later, on a night of pouring rain, the lie was exposed. Before she could even apologize, her father took her away from Namimori.

For years afterward, through countless long nights, she would repeat the words she'd never managed to say:

Thank you. I'm sorry...

And I love you.

I love only you.

Ten years later, Amamiya Mari got a chance to change her life.

Her grandfather, who lived far away in Italy, passed away. His butler found her and asked her to go to Italy and inherit the family estate.

Mari agreed without hesitation.

On the night she arrived in Italy, Mari represented her family at the birthday party for the Tenth Vongola Boss.

But could someone please explain how the good-for-nothing ex-boyfriend she had bullied ten years ago had become the Tenth Boss of Vongola, Italy's largest MAFIA family?

Reading notes:

1. One-on-one, pure romance, happy ending. The male and female leads have only ever loved each other.

2. The heroine was tsundere ten years ago and is now even more stubborn and prideful. She has a sharp tongue and is painfully conflicted. She loves Tsuna deeply but can't say it, so there will be some rather angsty scenes.

3. They sleep together from the start after reuniting.

4. They enter synesthesia dreams every night and gradually untangle their feelings.

5. The cover and character design were commissioned. The heroine is a silver-haired, green-eyed, tsundere young lady.

Theme: Face the past honestly and embrace a brighter future.
