The cost of the intensive care unit was six thousand dollars a day. By the third day of my grandmother's stay, my only savings of twenty thousand dollars had been used up.

I couldn’t get through to Ivy on the phone, so I sent her a message saying that I was going to sign a gift agreement with Grace.

Sure enough, she showed up at the coffee shop where we had agreed to meet on time.

I agreed to marry Grace's son Leonard, and Ivy was satisfied to receive five million dollars, but the condition was that she had to use half of the money to treat our grandmother's illness.

Ivy readily agreed. Rather than being unhappy about losing half of her money, I believe she was happier to see the miserable state I would be in after marrying Leonard.

A week later, Grandma was transferred from the intensive care unit to the general ward and was out of danger.

Leonard and I got our marriage certificate and moved into the villa that Grace bought for us.

On my wedding night, I laid out a whiteboard, pens, and a stack of advanced mathematics textbooks that I had prepared in advance.

When Leonard came out of the bathroom, his face turned as pale as frost.

I felt a little pleased with myself.

His Adam's apple bobbed nervously,

"What are you going to do?"

Possibly because I had set the temperature in the bedroom too high,

He walked to the bedside, picked up a glass of water, and drank it all in one gulp.

I lay on the mattress, sitting like a well-behaved student, tilting my head and looking at him calmly. "Of course, let’s play some exciting games that only adults are qualified to play—calculus."

Calculus.

Leonard frowned even more tightly as he watched me eagerly walk to the whiteboard and write a bunch of f(x) equations.

"Where should we start?" I paused and blinked at him. "Partial equations? Differential equations? Or limit derivatives? Newton and Leibniz are all entry-level. How about I give you some more difficult ones? Yang-Mills existence and mass gap hypothesis, or Navier-Stokes equations. Have you read them?"

However, the next second, these vicious numerical formulas from my mouth were fiercely sealed by two warm lips!

"No...wait!"

I didn't understand the situation at all.

I pulled myself away from his soft, aggressive kiss and took a breath. "Leonard, this isn't how your wedding night should be!"

He wrapped his strong arms around me and looked at me with affectionate eyes.

"Do you know how sexy it is when you say the Navier-Stokes equation? I just want to study the limiting negative distance deviation with you now."

Limit?

Negative...negative distance?

Oh my goodness!

On the morning after my wedding, I woke up in Leonard's tight embrace.

He was probably too tired from last night and hadn’t woken up yet.

The sunlight filtered through the gap in the clear white curtains and fell on his thick eyelashes,

causing a slight tremor with his breath.

My face flushed as I recalled every detail of last night, feeling confused.

Is Leonard the pervert that Ivy mentioned?

Although he was a bit crazy and perverted when he tormented me last night,

he would kiss me tenderly, listen carefully to my feelings, and considerately carry me to the bathroom to wash up afterward.

Apart from the fact that his rhythm seemed to follow the Fibonacci sequence, it didn’t seem as terrible as Ivy said, right?

Could it be that he saw that I was well-prepared, so he let me off on purpose to test my background?

I slowly pulled out my multi-functional self-defense bag from under the pillow and checked the pepper spray, Swiss Army knife, stun gun, and other items inside.

At that moment, Leonard suddenly opened his eyes. I forced a smile and said "Good morning" to him.

I forced a smile on my face and said "Good morning" to him.

But I didn’t expect Leonard to suddenly pounce on me like a madman, his eyes red, his hands tightly gripping my neck!

"I’m not, I’m not trash! If you dare say that again, I’ll kill you!"

"If you dare say that again, I'll kill you!"

I was stunned by his sudden attack and fell backward, my hands tightly clasped around Leonard’s wrists. "No, don’t... Leonard, let go...let go..."

"no, no..."

"Leonard, let go...let go..."

Just when I thought I was about to be strangled to death, he suddenly seemed to snap back to his normal self.

He picked me up, but I was coughing so hard I could barely breathe.

"Elaine, I...I just..."

"Don't touch me!"

I was still in shock. How could I dare let him touch me?

I shook off his hand, tears welling up in my eyes.

His behavior just now was definitely not something a normal person would do.

I hurriedly got up and tried to run outside, but he suddenly pulled me into his arms.

"I'm sorry, I didn't mean to..."

Leonard begged me not to run out like this. He pointed to the bruises on my neck and said, "If you leave like this, Lily will see the marks and she’ll definitely tell my mother. My mother thinks I’m fine, but if she sees you like this, she’ll be very worried."

What do you mean everything is fine?

I took a deep breath and said, "Leonard, tell me the truth. What happened to you just now?"

Leonard held me in his arms and looked at the marks on my neck with a distressed expression.

He explained that he had been diagnosed with post-traumatic stress disorder.

There had been no recurrences in the past few years, so he had stopped taking his medication.

"I don't know what happened just now. But the doctor said that even though my condition is well-controlled, I still need to be careful not to get too excited. Maybe I was a little too excited last night."

I cursed in my heart, "damn it, it wasn’t just a little."

Looking at Leonard's expression, it seemed as if he had never seen a woman in his life.

I had thought about it before. Leonard was handsome and tall, wealthy, with a gentle personality.

If such a good man didn't have some physical or psychological problems, would Grace have pushed him towards us?

However, compared to being innately perverted, a psychological problem caused by stress-induced trauma seemed a bit more manageable.

I turned around and looked into Leonard's eyes. After a while, I said, "Look, does the wound on my neck look like a curve in Euclidean space?"

Leonard's eyes lit up, he hugged me and kissed my neck.

At that moment, my cell phone rang.

It was Ivy. She called to wish me a happy wedding and said she would come to see me with her boyfriend Evan later.

I knew that she would be eager to see her "own masterpiece."

She would probably hope to see me tortured by Leonard, unable to get out of bed, with my body covered in bruises.

I hung up the phone and looked at Leonard with twinkling eyes.

I said, if you don’t want me to tell Grace, I can let you off this time, but don’t ever do it again.

However, my sister will be here soon, and you have to listen to me.

Leonard nodded repeatedly, and I felt relieved.

Just as Ivy was looking forward to meeting me, I was also looking forward to her shocked expression when she came to my house later.

She must have wondered why her perverted husband from her previous life was now wearing a pastoral lace apron, cooking, while I—

I leaned lazily on the sofa, with a flushed face.

"Elaine, are you feeling unwell?"

Ivy rushed over with concern, took my hand, and looked me up and down as if I were an animal.

She was obviously disappointed to see that I was neither missing an arm nor a leg.

"Nothing, sis. I'm fine. My waist just hurts a little."

I rolled lazily on the sofa like a cat. Leonard set the table for the meal and then lovingly lifted me up from the sofa.

He glanced at Ivy and smiled as gently as a spring breeze.

Seeing Ivy's mouth wide open,

I chuckled inwardly.

I guess she still didn't want to believe it?

How could the perverted husband from her previous life suddenly turn into such a good man in this life?

She didn’t believe it, so she grabbed my arm and looked up and down my waist, abdomen, chest, and shoulders.

She thought I must have internal injuries.

However, I could run and jump swiftly. I didn't look like I had been abused.

Only when Leonard sat next to me did I lean softly into his arms.

Even across the table of delicious food, I could feel Ivy's teeth grinding in frustration.
