Betrayed? I Upgraded to His Billionaire Brother novel Chapter 128

Was he ridiculing the failure of my marriage? Or was he secretly embarrassed that my husband could be called away by his mistress at any given moment without hesitation?

Gavin’s gaze bore into me, his expression unreadable yet tinged with something unusual. “I never thought your tolerance would stretch this far,” he remarked, the words hanging heavy in the air.

Tolerance—my endurance for my husband’s infidelity.

I caught the implication behind his words and responded with a defiant smirk, the corner of my lips curling upward. “He and I… we’ve reached an understanding. We each live our own lives now.”

A flicker of something dark crossed Gavin’s brow. His voice turned icy. “What did you just say?”

I maintained a steady, cold demeanor. “I said we have an open marriage.”

Gavin chuckled softly, his eyes locked onto mine with an intensity that made me uneasy. “How ‘open’ are we talking about here?”

My throat tightened, and my fingers clenched involuntarily as I avoided his piercing stare. “We’re just… doing our own thing.”

“Oh?” He shifted, placing one hand lightly near my thigh, leaning in with a teasing tone. “So, who exactly are you planning to ‘do your own thing’ with?”

“I—” I stiffened, caught off guard. “I’m still thinking about it!”

As if I had any real prospects! The Grayson family lived by the old, unspoken rule: what’s allowed for them isn’t for me. The moment I was caught in a compromising situation, I’d be cast out without a second thought.

Besides, my mind was buried deep in the project I was working on. Once it succeeded, Margaret wouldn’t dare treat me with such disregard anymore.

The car’s interior was bathed in the shifting glow of dim yellow streetlights, casting long, wavering shadows. I couldn’t quite read the emotions flickering in Gavin’s eyes, only hearing the subtle undertone in his voice. “Well, let me know once you’ve made up your mind.”

There was something strange about that invitation—something I couldn’t quite place. I instinctively recoiled a little.

I froze, my mind blank for a moment.

He was absolutely right.

It was as if he had pointed a finger directly at Gavin and named him outright.

But where would I find the courage to ‘do my own thing’ with Gavin?

The car cruised steadily down the street, the flickering streetlight shadows dancing across the man’s face beside me. His eyes narrowed slightly, silently questioning when I had developed such bold, reckless thoughts.

My heart pounded fiercely in my chest, threatening to betray me. Just as I was about to respond, his voice, deep and amused, resonated above me.

“Not only wanting an open marriage, but also wanting to play with such a… forbidden dynamic? I must say, that’s quite impressive.”
