My Heart Beats in His Mistress

She didn’t even have to think about it—Irwin was with his beloved Ava right now.

He completely forgot about his actual wife.

The smell of cigarette smoke drifting in from outside was unbearable, so Sue headed up to the fifth floor.

But to her surprise, the entire floor was blocked off, and the bodyguards stopped her from going any further.

“I heard Mr. Bondi booked the whole floor just so his wife can recover in peace!”

“Wow, Sue’s so lucky! She has an amazing husband!”

Hearing the chatter around her, Sue suddenly laughed.

‘Lucky?’

She wished that luck was actually hers.

Irwin was out taking a walk with Ava, and Sue followed from a distance.

“Irwin, aren’t you going to check on Sue? And… if you leave her behind to take care of me, what will people think of her?” Ava asked, her face full of concern, but deep in her eyes was a flicker of satisfaction.

Irwin’s voice was firm. “Come on, don’t joke like that. You’re the only one I care about. What happens to others has nothing to do with me.”

“But Sue is still your wife.”

“I don’t love her. I love you.”

Irwin took Ava’s hand and coaxed her gently. “Be good, don’t bring her up again.”

Then, as if no one else existed, the two kissed.

Under the sleeves of her coat, Sue’s hands curled into fists, nails digging so deep into her palms that blood dripped onto the floor.

She wanted so badly to rush over and demand to know why these two were doing this to her.

But in the next second, she turned and fled in humiliation.

It was late at night when Irwin finally remembered to check on Sue.

She was standing silently by the window when he wrapped his arms around her from behind.

“I’m sorry, Sue. Ava just got divorced. She has no one else to take care of her, and I couldn’t bear to leave her alone. You understand, right?”

Sue forced down the storm of emotions in her heart and answered with a quiet “Mm.”

Irwin let out a sigh of relief—until she suddenly asked, “Irwin, did my mom really die because of a failed surgery?”

She felt his body stiffen for a split second.

“Of course. Why are you asking this all of a sudden?” His tone turned cautious.

Sue lowered her gaze, her voice steady. “No reason. I was just wondering… Ava had a heart transplant too, but she survived. Why?”

“Sue, everyone’s body reacts differently. Your mom passed away simply because she couldn’t adapt to the surgery.”

Irwin lied without hesitation, even sounding a little annoyed. “Are you saying you think I deliberately caused her surgery to fail?”

Just then, his phone vibrated in his pocket. After checking the message, his expression changed slightly.

“Sue, there’s something urgent at the company. I have to go back—”

“Go ahead.”

Sue was exhausted—too drained to expose his lies.

Every time Ava called, Irwin had a different excuse.

‘Yesterday, something happened at the hospital. Today, it’s the company. And tomorrow?’

“Before you go, sign this insurance contract. The old one expired.”

She pulled a document from the drawer, flipped to the last page, and handed it to him.

Irwin, impatient to leave, signed his name without even looking before rushing out the door.

If he had taken just one glance, he would have realized—this wasn’t an insurance contract.

It was a divorce agreement.

Sue had no interest in staying at the hospital and wallowing in misery. She changed her clothes and headed straight to the law firm, handing the divorce papers to the lawyer.

“Once the company seal is stamped, please send it to this address.”

After that, she made another stop—the bar where Irwin and his so-called friends always gathered.
