A seemingly calm, secretly deranged woman x a perverse gentleman in disguise

(Only ever been with each other | International romance | Twisted love | Set in Italy | Both are mad)

Xu Jin's only reason for going to Italy is to find the man who ruined her sister's life.

Her sister was assaulted abroad and gave birth to a baby girl with a serious congenital illness before choosing to end her life.

The child urgently needs an organ transplant. Her only hope of survival is finding the man responsible.

The trail eventually leads to Elias Bianchi.

He is a refined psychologist in high society, born into one of Italy's most powerful families, with gentlemanly features and an easy, composed manner.

Xu Jin tests him at every turn. "Can I take a look at your body?"

Elias's polished identity is just a disguise. He is the true power behind the underworld.

A beast lurks beneath the gentleman's exterior.

The moment he met her, he saw the madness hidden beneath her hatred.

He recognized at a glance the same rotten streak in her that he carried within himself, and calmly accepted this prey that had wandered into his territory of her own accord.

He is captivated by the wickedness lurking in her eyes. They were made for each other.

Two twisted souls, perfectly matched by nature.

"I know you're just as healthy as I am."
