My Mate Regretted His Affair with My Sister when I Finally Dumped Him

Kathryn's Point of View

I clenched my fists, barely containing the rage as those memories flooded back. Once, I used to look at Ashton with admiration. But now, all I felt was the urge to make him suffer.

Going back to present, I shifted my gaze to Tiana, who was holding up a small mirror, inspecting the burn on her left cheek. I should have inflicted more damage.

Suddenly, Tiana let out a dramatic cry. "Oh, Ashton! This burn on my face looks so terrible! Kathryn's probably trying to make me look ugly because she's jealous that you love me!"

I raised an eyebrow at her theatrics.

"You can have Ashton all to yourself, Tiana. I'm literally asking him to end our mating bond right now. If he truly loves you, he would have ended it already, wouldn't he?" I said bitterly.

"Shut up!" Tiana screamed at me, then turned back to Ashton. "Ash, don't you think Kathryn deserves a punishment? Look what she did to me—I look horrible now!" She cried, clutching her face dramatically.

Ashton's fury intensified.

He then snatched the mirror from Tiana, aggressively broke it on the floor, and picked up a sharp shard.

He stepped toward me, his voice low and menacing. "Let this be your final warning. I don't want to see you using your cursed fire powers again, or I'll have you imprisoned."

I met his glare with a smirk. "Between the two of us, Ashton, you're the one who deserves imprisonment more. In fact, you should thank me for keeping silent all this time—for not exposing your dark secrets."

Ashton aimed the shard recklessly toward my face. "Enough of your nonsense. Apologize to your sister!"

"I will never apologize to her," I said firmly, lifting my chin.

He sighed, still holding the shard dangerously close to me. "Don't make me repeat myself, Kathryn. Do as I say, or else—"

"Or else what, Ashton?" I interrupted, my voice steady. "You'll cut my face with that shard? Go ahead—do it!" I moved even closer, pressing my face toward the sharp edge. "Wound my face, make it bleed, hurt me. I've endured worse pain from you. One more cut won't make a difference."

He stared at me, shocked by my defiance, before finally tossing the shard aside in frustration.

"So, you can't do it after all," I said.

Ashton clenched his jaw. "This conversation is over. There will be no severing of the mating bond, and that's final."

Tiana chimed in smugly. "Looks like Ashton still needs your maid services."

Without hesitation, I lunged toward her and slapped her hard across her right cheek. She gasped, eyes wide in shock.

"Learn to keep your mouth shut when no one asks for your opinion." I spat before slapping her again, evening out the redness on the other cheek which had been slightly burned.

"There you go—an instant blush, dear sister. Now you won't look so ugly." I added, my voice dripping with sarcasm.

As expected, Ashton rushed to Tiana's side, comforting her with gentle kisses on each cheek—a sickening display that only deepened my disgust.

"I still can't believe you're capable of fighting back now, Kathryn…" He muttered, clearly unsettled.

I smirked, unfazed.

The Kathryn who once obeyed his every command, lowered her head, pleaded, and shed tears for him was gone.

I had killed that part of myself.

Thinking about it now, I could only laugh at how foolishly I had fallen for him.

Back when we were newly mated, Alpha Philip had asked us to live at the Fire Heart Kingdom with him for a while. Of course, under his father's watchful eye, Ashton was forced to show me kindness, a hint of affection, and even the appearance of love.

I remember those days well.

Once, when someone bullied me and shoved me into the rose bushes at the kingdom, Ashton immediately helped me up, his fury aimed at the bully.

"This behavior will reach the Alpha! Apologize to her right now!" He commanded, his voice fierce. The bully, intimidated, dropped to his knees and apologized.

Later that night, Ashton came to me with a medical kit in his hands. "Did the rose thorns hurt you?" He asked softly, reaching for my arm. With tenderness, he dabbed my skin with a damp cotton ball, careful with every touch.

There were other moments too—times when Ashton would prepare meals for me, look after me when I was sick, bring me flowers and gifts, take me to the farm to feed the cows, and even teach me to ride a horse.

Those moments felt genuine.

But his tenderness only lasted for a year, just long enough for me to fall deeply in love with him.

I truly believed he had changed, that he'd finally learned to love an Omega like me.

But it turned out he was only putting on a show, biding his time until Alpha Philip granted us our own mansion.

The moment Ashton received the mansion, everything changed. His kindness vanished, replaced by cold indifference and resentment.

Unfortunately, my feelings for him didn't fade…

"Do you really think I could love someone like you? In your dreams, Kathryn!" He yelled, his voice filled with contempt.

I forced a smile, my heart breaking. "It's okay. I still love you, and I'll keep on loving you."

"Enough with the drama," He sneered, stepping closer. "Listen. I don't want any of this reaching my father. Do you understand me?" His voice sounded like a threat, so I swallowed hard and nodded.

Because I was completely blinded by my love for Ashton, I foolishly kept quiet and learned to submit.

Honestly, I still have feelings for him now, but I know those feelings are already changing—quickly.

Back to reality, I glared at him. "I'm capable of fighting back now because, after all these years, I'm finally learning how to unlove you—no, to hate you."

His head tilted.

"That's right. I want to sever our mating bond because I fucking hate you, Ashton Grey," I stated.
