Eight months pregnant, I accidentally discovered my Alpha husband Coran was cheating on me with my sister Mira, who had come to take care of me.

When I caught them, his tone was flat:

You found out? Actually, I've been sleeping with her since your third month of pregnancy. These past few months, I've been taking her to hotels every night... Who told you to never let me touch you during your pregnancy?

I couldn't help but raise my hand and slap him across the face. "You bastard! She's my sister!"

Mira dropped to her knees in front of me, tears streaming down her face. "Rowenna, don't blame Coran. I was the one who started it..."

My brain buzzed, and my body swayed. Coran caught me in his arms.

I dodged his hands. "Why?"

Mira bit her lip, struggling to speak. "I've always had feelings for him..."

I slapped her across the face.

Coran shielded her behind him, his eyes cold as ice:

"I'm a man, and I have needs. Isn't this arrangement better? She's your sisterwe're all family. Would you rather I cheated with some stranger?"

I stood frozen in place, my throat feeling like it was stuffed with cotton.

Coran sighed helplessly and gently wiped the tears from the corners of my eyes. "Rowenna, it's just your pregnancy hormones making you overthink everything. Don't get so upsetit's bad for the baby."

The familiar features before me suddenly seemed like a stranger's.

So he did remember I was still pregnant.

Mira scrambled up and headed to the kitchen, her legs still trembling as she walked. "Rowenna, what would you like to eat? I'll make it for you..."

Their concerned expressions made me feel like everything that just happened was a dream.

"When did it start?"

Coran frowned slightly. "January 25th. That day you went for your prenatal checkup and asked Mira to bring me some documents. I couldn't control myself..."

The bright red hickeys on his neck stung my eyes.

The baby in my belly kicked me again. My back hurt so much I couldn't straighten up, and tears fell in heavy drops onto the floor.

So it was that day.

I had taken a taxi to the hospital alone, waited in line, got my number, went through the checkup.

I asked Coran if he could come with me, but he said he had work matters at the pack that needed his attention.

I asked my sister if she could help me, but she said after delivering the documents, a friend needed her help.

My legs were swollen during pregnancy, and someone bumped into me at the hospital. I almost had a miscarriage.

The two people closest to me were locked in passion on his office desk.

And I kept making excuses for him, thinking he was just too busy. I never imagined he was busy in my own sister's bed.

It turned out I was the only fool.

Coran suddenly crouched down and rubbed my legs. "If you hadn't found out, you wouldn't be sad. Wouldn't it be better to just keep playing dumb?"

"Every time we had sex, we deliberately chose hotels far from home so the mate bond wouldn't affect you and make you uncomfortable."

My stomach churned, and I kicked him hard in the chest.

"Coran, you disgust me!"

He took advantage of the momentum to help me onto the couch. "If this makes you feel better, you can kick me a few more times."

As I struggled, my hand touched something on the couch.

I lifted it to seea pair of torn stockings.

The blood in my body seemed to turn ice cold.

Coran looked like he wanted to say something but stopped.

Mira walked out carrying soup, saw what was in my hand, and her face went white.

She rushed forward to explain in a panic. "Rowenna, it's not what you think..."

Coran calmly took the stockings, his tone casual. "No need to make such a fuss. Yesterday you said you were going back to your mother's house and wouldn't be home that night. That evening I tried something new with your sister on the couch. Not only that, we also went to the bedroom and had sex on your marriage bed. I have to say, it was pretty thrilling."

Tears blurred my vision.

I suddenly stood up and rushed into the bathroom, vomiting violently.

Outside the door came Mira's worried voice. "Rowenna, are you okay? Coran's just talking nonsense. Don't get upset. Your health is most importantyou still have a baby inside you."

The nausea only deepened. I looked at my swollen belly in despair.

Why did it have to be at eight months?

Why did it have to be Mira?

Since childhood, I'd given in to her in everything.

When her fated mate died, I stayed by her side through the night, constantly comforting her.

She said my house was closer to her university, so I let her move into the villa I shared with Coran.

The jewelry and luxury goods on her bodyI bought them all for her.

I opened the door and stared at Mira. "Haven't I been good enough to you?"

Mira ingratiatingly handed me a bowl of soup, her tone cautious. "Rowenna, please eat something. After you eat, we can talk, okay?"

I knocked the soup bowl from her hands. The scalding liquid splashed on the back of her hand, turning it bright red.

"I don't need your fake kindness!"

Mira's eyes instantly reddened. "Rowenna, how can you say that about me!"

Coran's face darkened, glaring at me with displeasure.

"If you're angry, take it out on me. Mira's just concerned about you. Do you have to make such a big deal out of nothing?"

He rubbed his temples while gently wiping Mira's tears. "See? I told you we couldn't let Rowenna find out. Your parents were rightRowenna's temper is just difficult. If she knows, this household will be turned upside down."

Mira looked at me with tears in the corners of her eyes, her face full of grievance.

I felt like I was choking. Since childhood, she'd always been like this.

"I'm taking Mira to the hospital. You stay home and reflect on yourself!"

He slammed the door so hard it shook.

I slumped powerlessly into a chair, but soon a strange smell came from the kitchen. They'd left in such a hurry they hadn't even turned off the gas...

I struggled to move my body to open the door, only to discover that Coran had broken the lock when he slammed it.

I desperately called Coran.

Call after call, all rejected.

Until the last onehe answered, his voice impatient. "Can you stop being so paranoid? Because of you, Mira cried herself hoarse, keep asking if Rowenna really hates her. She really cares about you."

I dragged my heavy pregnant belly, my whole body weak and powerless. "Coran, I..."

"I'm busy comforting Mira. If there's nothing else, I'm hanging up."

The phone went dead with a beeping sound. The smell of gas had almost filled the entire house. I finally felt despair.

Coran, I won't love you anymore.

When I woke up, my mom was lying by my bedside.

Overcome with grievance and fear, I instinctively hugged her, my voice choked. "Mom..."

"Coran cheated on me."

My mom interrupted my tearful complaint. My heart felt like it was being squeezed by a giant hand.

"It's such a small thing. Do you really need to act like you want to die? What man doesn't cheat?"

I became emotional. "But the person he cheated with is..."

Her tone was calm. "I know."

I looked up in disbelief at my mother's murky eyes.

No guilt whatsoever, only dissatisfaction with me.

I grabbed my mother's arm, my voice hoarse with emotion. "You know? You knew and you still..."

"Your husband is an Alpha. His work is stressful and he needs an outlet. As his wife, you don't understand himfine."

"Outsiders cost money. Your sister is clean. Isn't it good that she's sharing the burden for you? What do you have to make a fuss about?"

Her mouth opened and closed, every word scolding me for being unreasonable. My mind went blank.

Even though I'd long known her favoritism had no bounds.

Even though I'd long known Mira was the apple of her eye.

I still couldn't understand. I broke down, screaming and questioning her.

I thought she could at least show some concern for me, but instead she said, "When I gave birth to you, my body was ruined because of you. You've been ungrateful since childhood, always fighting with Mira over things. Now you even want to fight with Mira over a man!"

My fingernails almost drew blood.

My father was the previous Beta of Bronzefang pack. He died when I was young in a Rogue attack.

I was still immersed in the pain of losing my father when my mom came up and slapped me twice across the face, pointing at me and cursing:

"I knew ityou're nothing but bad luck! It wasn't enough that you ruined my body when you were born. Now you've brought your curse to your father, making him die so young!"

Later, when I was eighteen, I became the fated mate of Coran, an Alpha. After we married, I became the pack's Luna.

I thought my mom would stop calling me bad luck. I thought my mom would finally like me. But it turned out she'd always hoped it would be Mira who married Coran and became Luna.

My phone buzzed with a notificationone of my special alerts.

Mira had updated her social media:

"Feeling down. Coran rented out the entire Ferris wheel just for me."

I was lying in the hospital from gas poisoning.

My husband was accompanying my sister to the newest Western restaurant, taking her to the amusement park, riding the Ferris wheel with her.

"If you can't keep your Alpha's heart, who can you blame?"

My mother's flippant mockery made my red, swollen eyes look especially ridiculous.

When Coran and Mira came back, I was still in the hospital waiting to give birth.

"Rowenna, I'm so sorry. I forgot to turn off the gas when I was cooking. If it weren't for me, you wouldn't have..."

Mira cried pitifully, but I didn't even bother to look at her.

She cried harder. "Coran, is Rowenna mad at me? I'm so stupidI can't even handle such a small thing."

Coran comforted her gently. "It's not your fault."

He looked at me, seemingly displeased with my attitude. "Rowenna, Mira is apologizing to you. Are you deaf?"

I suddenly felt like laughing, but tears fell against my will.

Coran realized his tone was too harsh and softened it. He pulled out two stuffed animals. "I know this scared you. I asked the doctoryou and the baby are fine. Mira is still young. She even brought you the stuffed animals you like."

The gemstone necklace on Mira's neck was blindingly conspicuous.

It was the wedding gift I'd asked Coran for over a year.

To this day, my neck remained empty.

Did I only deserve these cheap dolls?

I bit my lip almost hard enough to draw blood. "In what capacity are you speaking for Mira? Brother-in-law? Lover?"

Coran's expression gradually darkened.

He let out a cold laugh.

"No wonder your mom doesn't like you."

"Mira is sunny and cheerful, unlike youpetty, narrow-minded. If I were your mom, I would also..."

I looked up in disbelief.

Coran's eyes showed panic. "That's not what I meant..."

For as long as I could remember, my mom hadn't liked me. Even when there were two chicken drumsticks, she'd give both to Mira.

When I was little, every friend I made would be drawn to Mira and become her friend instead.

Every night in the quiet darkness, I hated myself for not being as likable as Mira.

It was Coran's appearance that told me even if I wasn't perfect, he would always stand by my side.

But now, even he was standing on Mira's side.

My tears flowed like an opened faucet, uncontrollable. I broke down, grabbing things and throwing them at him. "Get out! Just get out!"

Over the next few days, probably out of guilt, Coran and Mira came to the hospital to see me every other day.

Baby diapers and wipes, all kinds of pregnancy nutrition mealsan endless stream.

"Rowenna, didn't you say before that you really liked this necklace? I bought it specially for you."

The necklace I'd wanted for so long was placed in my palm by Coran, but it felt cold all the way to my heart.

One year and three months. He knew I liked it, but never thought to buy it for me.

I lifted my head and finally said the words I'd been holding in my heart.

"Let's get divorced."

We spoke at the same time.

I looked up in shock, only to see Coran's face light up with joy.

"That's great! Rowenna, you know?"

Confusion flashed across my face.

Coran had already pulled out divorce papers. "This is the divorce agreement. If everything looks good, just sign it."

"After all, we as a married couple owe Mira. I'll marry her, and you'll give up your Luna position to her so she can participate in pack affairs as Luna. Consider it compensation."

"Don't worry, we won't break the mate bond. You'll still technically be my wife. I'll take care of you anyway. Being a housewife from now on isn't bad."

By the time I finished signing, I finally processed what Coran had said.

"Coran, do you remember what you promised me?"

Coran paused, seemingly trying to recall.

Clearly, he'd forgotten. When I spent two years trying to conceive, drinking countless potions from witches and taking countless fertility shots before finally having this child, he'd promised me, "You've sacrificed so much for me. I'll make sure you become the most respected and happiest Luna among all the packs."

Now he wanted a divorce and to make Mira the new Luna.

The door opened and Mira walked in. "Rowenna, are you feeling better?"

Coran warned me with his eyes not to say anything.

I smiled with tears in my eyes. "How can I be better with a bitch like you around? Seducing my husband wasn't enoughnow you want to steal my Luna position. Mira, you're shameless beyond belief."

Her face went white as a sheet.

Tears fell like broken pearls.

Coran's face darkened. "Rowenna!"

"Am I wrong? She's barely in her twenties and already knows how to climb into her own brother-in-law's bed! Isn't that slutty?"

I raised my voice. People around us looked at her with mockery.

Coran pulled her into his arms and sneered at me. "Who's more slutty than you? At eighteen, you went to a bar and someone drugged you with an aphrodisiac. I took you to the hospital, but you refused treatment and insisted on having sex with me in the woods..."

Contemptuous ridicule echoed around us.

My face went from pale to red. I lunged at him in fury.

Mira suddenly blocked his path and took the slap. "Rowenna, if you're going to blame someone, blame me. Everything is my fault. Coran already works so hard."

"Rowenna, what's wrong with you!"

Pain flashed in Coran's eyes as he pushed me away roughly.

My belly hit the corner of the table hard. Blood spread beneath me.

Coran shouted for a doctor in shock. Mira cried and hit Coran.

"Rowenna, I didn't mean to. Please don't let anything happen to you..."

Coran watched with tears as I was wheeled into the operating room.

In the darkness, surgical clamps spread me opena tearing pain.

I cried my heart out. My life flashed before my eyes like a panorama.

It was eighteen-year-old Coran on the grass, fingers intertwined with mine. "Rowenna, I'll treat you well for a lifetime."

A lifetimeit turned out to only be seven years...

The baby was born premature and went into an incubator.

Coran gripped my hand guiltily, his eyes red. "Rowenna, I'm so sorry. I didn't mean to push you. When this summer ends, I'll make Mira leave our house."

I turned to the side, tears flowing silently.

After being discharged, Coran locked me in the house. He even hid my phone.

The first day, they only brought three meals. I held my newborn baby and cried inconsolably.

The second day, I smashed everything in the room and cut my hand.

The third day, Coran finally came to see me.

I broke down and demanded to know why he wouldn't even give me the right to move freely.

He frowned as he bandaged my hand, his expression helpless. "You're too emotional right now. I'm afraid you'll go out and ruin Mira's reputation. She's still a young woman. We can't let your temper destroy her life, can we?"

Mira beside him gave me a sympathetic look. "Rowenna, don't worry. I'll definitely be a good Luna for Bronzefang pack. I'll help maintain your friendships too."

My heart felt like a piece of flesh had been carved out.

I looked disheveled, my face bloodless. "Coran, what gives you the right to let someone else replace my life! Is this what you call love?"

Coran froze for a moment, his patience exhausted. "When you learn how to be a gracious mother, I'll naturally let you out."

He wanted me to learn to be a gracious mother while stripping away my marriage, my work, my freedom.

Meanwhile, Mira enjoyed everything that should have been mine under his protection.

I covered my face, laughing until tears streamed down.

The baby beside me suddenly began wailing. I touched the child's burning forehead, my heart twisting with pain.

"Coran, let me out! Jack has a fever!"

I pounded on the door hysterically, my nails leaving bloody scratches.

The crying finally brought Coran.

He frowned. "What are you making a fuss about now?"

I begged without dignity. "Coran, please look at Jack. He's your son! He could really die!"

Hesitation and conflict flashed in his eyes. "But..."

My mother suddenly entered. She glanced once and said flatly, "Making a big deal out of nothing. You had fevers when you were little too. Some fever medicine will be fine. You're making such a scenecould it be because... today Mira is giving her speech as the new Luna? You wouldn't be trying to sabotage her work, would you?"

Coran's expression instantly darkened. "Rowenna, enough is enough. When did you become so unreasonable? Using even your son as an excuse."

I laughed until my whole body shook. "I'm unreasonable?"

He looked puzzled. "Mira is your sister. Why can she accept all this, but you can't?"

It was as if my breakdown and helplessness were trivial in Coran's eyes. He took a phone call, a smile spreading across his face as he strode away. "Mom, Mira's speech is about to start. Let's go."

I looked at the child in my arms, his face flushed red. As if I couldn't feel pain, I desperately kicked down the door.

But I was covered in blood. Drivers who passed by didn't dare let me in their cars. When I finally got a ride, I realized Coran had confiscated my phone, and I had no bank cards or cashno way to pay. The driver kicked me out.

By the time a kind person took me to the hospital, the doctor shook his head helplessly. "Why didn't you bring him sooner? The child was already premature. You're too careless as a mother."

Holding my child's cold body as I returned home, my heart dead as ashes, I lit a fire.

In the flames, the roar of a helicopter was particularly harsh.

A figure slowly walked toward me...

"I'm sorry. I came too late."
