The discovery beneath Luca's father's old estate changed everything.
For years, Luca had believed he understood the world he lived in. He believed he knew his enemies, his allies, and the reasons behind every battle he had fought.
But now, every truth he had built his life around was beginning to collapse.
And the one person standing beside him through it all was the one person he had never planned to need.
Isabella.
The woman who entered his life as part of a challenge.
The woman who was supposed to be temporary.
The woman who had somehow become permanent.
The drive back to the estate was silent.
Not the uncomfortable kind of silence.
The kind filled with thoughts too heavy to say out loud.
Isabella watched Luca from the passenger seat.
He looked calm.
Too calm.
She knew him now.
She knew that when Luca became quiet, it wasn't because he had nothing to say.
It was because he was trying to control everything he was feeling.
"You're blaming yourself."
His eyes stayed on the road.
"For what?"
"For not knowing."
A pause.
"Maybe I should have."
"Luca."
"My entire life has been built on knowing."
His grip tightened slightly on the steering wheel.
"I know how to negotiate. I know how to fight. I know how to protect what belongs to me."
His voice lowered.
"But I didn't know this."
Isabella looked out the window.
"Maybe because it wasn't yours to discover alone."
He glanced at her.
"What do you mean?"
"You keep acting like every problem in your life is yours to solve."
A small breath left him.
"Because it is."
"No."
Her voice was gentle but firm.
"Not anymore."
Those words stayed with him.
Not anymore.
Because that was the change Isabella had brought into his life.
Before her, Luca carried everything alone.
After her, he was learning that sharing a burden didn't make him weak.
That night, the estate was quieter than usual.
The guards remained outside.
The security remained active.
But inside the walls, Luca and Isabella finally had a moment away from the chaos.
A moment to remember who they were before secrets and enemies took over.
Isabella walked into the bedroom and noticed something on the table.
A small black box.
She looked at Luca.
"What is this?"
He leaned against the doorway.
"Something for tonight."
Her curiosity grew.
"You planned something?"
"For once, yes."
A small smile appeared on her face.
"Should I be worried?"
"No."
He walked closer.
"Tonight isn't about the danger outside."
He looked at her.
"Tonight is about remembering why this started."
Isabella understood.
The 90-day challenge.
The promise they made to explore each other, not only through attraction, but through trust.
Because somewhere between secrets and threats, they had forgotten that their connection began with curiosity.
With two people wanting to discover something new.
The first days had been about testing boundaries.
But the deeper they went, the more they discovered that desire wasn't only about excitement.
It was about vulnerability.
It was about allowing someone to see parts of you nobody else had access to.
Luca opened the box.
Inside was a journal.
Isabella looked confused.
"A journal?"
"Yes."
"Why?"
"Because I realized something."
He handed it to her.
"The days are passing, but we're not remembering them."
She opened the first page.
At the top, Luca had written:
Day One.
She looked at him.
"You kept track?"
"I remember everything."
The answer was simple.
But it meant more than he realized.
Isabella smiled softly.
"You're much more sentimental than you pretend."
"Don't tell anyone."
She laughed.
And Luca watched her.
Really watched her.
As if her happiness was something rare.
Something worth protecting.
They spent the evening away from everything that usually surrounded them.
No business.
No enemies.
No discussions about the past.
Just conversations.
They talked about childhood memories.
Dreams they had abandoned.
Things they feared.
Things they secretly wanted.
Isabella learned that Luca's favorite moments were not the expensive ones.
Not the powerful ones.
Not the moments where everyone feared him.
They were the quiet ones.
The rare moments when he could forget who the world expected him to be.
And Luca learned things about Isabella too.
That she was stronger than she believed.
That she had a stubborn heart.
That beneath her confidence was someone who wanted to be chosen.
Not controlled.
Chosen.
Later, as they sat together, Isabella looked at the journal again.
"Do you think we changed?"
Luca looked at her.
"Yes."
"How?"
He thought for a moment.
"Before you, I thought desire was about wanting something."
"And now?"
"Now I think desire is about understanding why you want it."
The answer surprised her.
Because it wasn't what she expected from him.
But Luca had always been full of contradictions.
The dangerous man who wanted peace.
The powerful man who feared losing someone.
The man who claimed not to need anyone but held onto Isabella like she was the only thing keeping him grounded.
A sound interrupted them.
A message.
Luca's phone.
His expression changed instantly.
The past had returned again.
Isabella saw the shift.
"What happened?"
He showed her the screen.
A picture.
New evidence.
A woman.
A location.
And a message.
The truth about your families begins where the first betrayal happened.
Isabella looked at Luca.
"Where is that?"
His face became unreadable.
"Where my father started everything."
"And?"
His eyes met hers.
"Where Sofia disappeared."
The mystery had opened another door.
A door that would lead them closer to the truth.
But Luca knew something Isabella didn't.
Every secret uncovered came with a price.
And this time, the price might be the relationship they had fought so hard to build.
Because the 90 days were not just testing their desires anymore.
They were testing whether their connection could survive the truth.
