Cheating Husbands are Cancer
That was my duty, as his wife of ten years.
When he came to, he just stared up at the ceiling for a long while, without making a sound.
I peeled and cut an apple, then pressed a slice against the corner of his lips. At last, he stirred—but all he did was flinch aside, with a vehemence which suggested he was deeply upset with me.
"You already knew, didn't you?" he hissed.
"About what? That you lied about having late-stage cancer, in the hopes that I'd cede everything to you after we got divorced? Or perhaps you're talking about the mistress you've been keeping hidden at your mom's place—the one you knocked up?"

Ditching My Cheating Alpha
"Haven't I treated you well all these years? We waited three years for this child! How could you just get rid of it? Did you even think about how I would feel? Pearl, when did you become so heartless?"
His voice was strained, his anger barely contained. Beneath it, there was heartbreak, desperation, and sorrow. He sounded like the victim, as though I were the one who betrayed him.
I snapped.
"Boweike, you cheated on me! You lied about work while you spent your time with Mia! You traveled the world with her! You showered her with gifts and sweet words! And the worst part? You did all of that while I was pregnant with your child! Boweike, did you ever think about how I felt?"

When Dad and I Are Both Branded as Cheaters
"Mr. Keller Senior, I never meant for this to happen. I'm the Keller family's daughter-in-law. I never intended to hurt Elias or Christopher."
Gregory, still clutching his hand in pain, froze. He stared at Mom in disbelief. "Daughter-in-law? What do you mean by 'the Keller family's daughter-in-law?' Selena Ashford, you really did cheat on me!"
Caught between shock and fury, he shouted for someone to hit her.
Mom shot to her feet and slapped Gregory hard across the face. Cold sweat ran down her face as she growled fiercely, "Shut your mouth! Stop this right now. He's not someone you can afford to mess with!"

He Cheated With My Bestie. Now He Begs for Mercy
Whether it was me bailing on him for a friend, smashing one of his precious collectibles, going away for a sudden work trip, or even being asked out on a date by my long-time admirer, he never got mad once.
I had always thought I had found the perfect man with high emotional intelligence, but it turned out that "good temper" wasn't a virtue, but something masked by sheer guilt.
After we started dating, Jared began giving me expensive gifts—necklaces worth a fortune, custom high fashion from the pack's famous designers.
I thought they were proof of his love, but they were only a counter for the number of times he had cheated on me. He felt a brief stab of guilt every time he came home from fo

Wealth, Cheating, and Prison
With that, I picked up my bag and strode away under everyone's shocked gazes.
When I stepped out of the cafe, the sunlight was blinding.
My phone vibrated with a message from James. [The offshore accounts have been traced. The fund flows are quite interesting—besides Wendy, a huge sum also went to an overseas casino.]
I halted mid-step.
So Cameron had not only cheated and transferred assets—he had also been involved in gambling.
That made things even more interesting.
That very evening, I received an invitation.
It was to the industry's top-tier "Golden Architecture Award" gala.

I Sent My Cheating AI Incubus to the Scrapyard
Once, I asked him to drive me out for the day, and he rammed the car straight into a guardrail.
After he finally got me out, he looked guilty and explained,
"Sienna, it's probably impurity buildup from too much contact. It's throwing off my arousal threshold and causing faults."
"Let's keep our distance for a while. I can't keep up with your needs anymore."
I actually felt guilty, deciding I was just too possessive and that I was dragging him down.
Until one day, I caught a livestream from my housekeeper, Vivian Shaw.
"Okay, girls, time to live like the rich. Let's try out the boss's top-of-the-line robot."

Rejected Plus-Size Wife, Claimed by My Husband’s Brother
When I finally turned it on, messages flooded in.
Matteo: Please don't do this, I know I messed up.
Matteo: You're the reason I'm cheating. No man is attracted to a fat woman.
Matteo: Okay, I'm sorry. I'll never see her again. I'll fire the escorts, I'll sleep in our room every night.
Matteo: For Nia's sake, please don't tell your parents. I'll change. I promise.
I turned the phone off and stared out the dark window.

HER INSECURITY, MY TEMPTATION--MAFIA
They were moving in line, one after another, the best way to detect any spy trying to mingle with us unnoticed.
“This is the right time to increase your wealth and power by being with Grace Moretti,” he continued after noticing I was not giving him the attention he desperately wanted. “That commoner you are chasing after should be shot in the head on sight. She is a cheater! Matvei… listen to me. She is an adulteress.”
His words made my chest tighten painfully. Hearing it said out loud made something slam hard against the side of my skull.
And so what if she fucking cheated on me?!.

Breed Me. Daddy Alpha
Why was I suddenly imagining myself on all fours, whining, begging, presenting for him like my wolf wanted to be filled so deep I couldn’t shift back?
“That’s not fair,” I whispered, grinding into his palm like I’d lost my mind. “You can’t say that shit while you’ve got your fingers in me. That’s cheating. That’s evil. That’s illegal. I’m 18. I don’t have the emotional maturity for that kind of fantasy.”
He chuckled.
Chuckled.
Like he knew he’d already won.
“You’re thinking about it,” he murmured, kissing my cheekbone. “You’re picturing it. Your little tail lifted. My teeth at your neck. My knot stretching you so wide you forget you were ever human.”

My Mate's Father Wants Me
“You're one great guy, Vince. You don't go to nightclubs but one night you decide to go, you're determined not to cheat on your mate. I hope Vanessa knows how lucky she is to have you.”
Leonardo was done with his eulogy and was now sucking hard on the girl’s tits while the others waited their turn. Teasing him while they waited.
A sting clawed at my heart at his words. I gulped another shot, groaning as the booze hit right on the sore part of my heart.
Yeah, I'm one great guy, who's been emotionally cheating on my mate for years.
And not too long ago, I added physical cheating to the list.
I'm a great guy who's obsessed with a 22 years old who disrespects the fuck out of me.

Frequently Asked Questions
If you're hunting for manga that don't shy away from messy, adult romance and the thorny ethics of cheating, I have a handful that hit hard and stay with you. I devoured 'Kuzu no Honkai' ('Scum's Wish') and loved how it frames infidelity as a symptom of longing and loneliness rather than just melodrama; the characters are flawed, painfully honest in their selfishness, and the art captures that emotional rawness. 'Domestic na Kanojo' gets shout-outs too — it's loud, chaotic, and ethically fraught in ways that force you to keep turning pages even when you cringe.
For a grittier, more tragic angle, 'Nana' is essential: it's not strictly about cheating all the time, but betrayals and adult compromises are central to how the characters evolve, and it's brutal in a very human way. If you want something explicitly about the NTR vibe, 'Netsuzou Trap -NTR-' leans into temptation and secrecy with a tense, intimate focus. Fair warning — these titles are best for mature readers: they include sexual content, manipulation, and psychological hurt. Personally, I appreciate how these works treat infidelity as complex storytelling fuel rather than cheap sensationalism.
