Betrayed by My Ex, Marked by His Alpha Emperor Brother

Elara’s POV

Lyra’s sobs hit me like a blade between the ribs.

I didn’t think. I moved. Up the stairs, past Kaelen, past everything—straight to her.

She collapsed into my arms before I reached the top step. Her small body shook violently, hiccupping breaths rattling through her chest. Her fingers dug into my cloak like she was drowning.

"Mother—Mother, please—don’t go—"

"Shh. I’m here." I pressed her face into my shoulder. "I’m right here."

Valerius stood behind her, still as stone. Tears tracked silently down his cheeks, but his jaw was locked tight. He didn’t reach for me. He watched with those gold eyes—hard, ancient, betrayed.

Kaelen had followed me up the stairs. He hovered at the landing, haggard. Hollow. His mouth opened, then closed. He looked like a man watching his house burn from across a river.

I ignored him.

"Mother," Lyra whimpered against my neck, "you and Father were fighting again. I heard you. I heard the yelling."

"No more yelling," I whispered. "No more tonight."

"Promise?"

"Promise."

She pulled back, her face blotchy and swollen. Snot glistened on her upper lip. She looked so small. So fragile. So much like me, and so much like him, and the combination was unbearable.

"Stay tonight," she begged. "Just tonight. Please. Sleep in my room. You can have my whole bed. I’ll sleep on the floor. I don’t mind."

"You are not sleeping on the floor, little princess."

"Then we share. Please. Please, Mother."

I looked at Valerius.

He met my gaze. Cold. Guarded. Then he spoke, and his voice was a blade wrapped in silk.

"Go."

One word.

"Val—"

"We don’t need you." Each syllable was deliberate. Precise. Practiced. "You always leave. So just leave now and stop pretending."

The words landed exactly where he aimed them. Center mass. I flinched.

Lyra wailed. "Valerius, stop! Don’t say that—"

"It’s true." His voice cracked on the second word, betraying him. He swallowed hard and rebuilt the wall. "Every time she comes, she leaves. Every time. It’s worse when she stays first. So just—go."

He took Lyra’s hand and pulled her gently away from me. She resisted, reaching back, fingers grasping.

"No—I want Mother—"

"Come on, Lyra."

He guided her toward her bedroom door. She twisted in his grip, sobbing, stretching one arm toward me.

"Mother!"

"Lyra." I caught her hand. Held it. My son’s eyes burned into the side of my face, daring me to make another promise I wouldn’t keep. I crouched down and cupped her wet cheek. "Tonight. Just this one night. I’ll stay."

Her crying stuttered. "Really?"

"Really. I’ll be right beside you. All night."

Valerius’s grip on her other hand tightened. He stared at me for a long, scorching moment. Then he released Lyra without a word, stepped into his own room, and shut the door behind him.

The click of the latch was louder than any shout.

I gathered Lyra up. She clung to me—legs around my waist, arms around my neck, face buried in my hair. I carried her into her bedroom.

I laid Lyra on the bed and pulled the quilt over her. She wouldn’t release my hand.

"Stay," she murmured.

"I’m staying, my little sweetheart."

I kicked off my shoes and lay beside her. She curled into me immediately—her back against my chest, my arm draped over her, her small fingers laced through mine. Her breathing slowed. Hitched. Slowed again.

"Mother?"

"Hmm?"

"I love you."

"I love you too, my little princess. More than anything in this world."

She was asleep soon after.

I stayed perfectly still, listening to the rhythm of her breathing, feeling her heartbeat against my arm.

When enough time had passed and the room was thick with silence, I carefully extracted myself from Lyra’s grip. She murmured but didn’t wake.

I moved through the corridor like a ghost. The study door was open. Moonlight spilled across the desk in a pale stripe.

I sat. Found paper. Found ink.

The pen hovered. My hand trembled.

Then I wrote.

Kaelen,

I am sorry for leaving the way I did years ago. I should have spoken to you directly. That was a cruelty I regret, regardless of what drove me to it.

But I cannot stay in this marriage. Not like this. Not anymore.

I am requesting a formal legal separation. A full dissolution of all marital bonds, witnessed by the Imperial Court and the Council of Elders. I want fair division of shared holdings and guaranteed access to our children on terms we both agree to.

Seraphine deserves the chance to be your empress. She carries your heir. Give her what you never gave me—honesty.

Do not come looking for me tonight.

— Elara

I folded the letter. Set it in the center of the desk where he would find it.

Then I left.

The carriage ride back was silent. The driver didn’t speak. I didn’t speak. The streets were empty, the city asleep, and the only sound was the rhythmic clatter of hooves on cobblestone.

My rented lodgings sat at the end of a narrow, crooked lane. The walls leaned. The paint peeled. The single lantern by the door had gone out again.

I stepped down from the carriage and stopped.

Someone was standing at my door.

The silhouette was unmistakable. Slim. Poised. One hand resting protectively on the prominent swell of her belly.

Seraphine.

She turned as I approached. Moonlight caught her face—composed, serene, radiating the particular smugness of someone holding a winning hand.

Her pregnancy was undeniable now. The curve of her stomach pressed against the fine fabric of her cloak. She was obviously several months along.

"Elara." She smiled. Warm. Gentle. The kind of smile you’d give a wounded animal before putting it down. "I hope I’m not intruding."

"What are you doing here?"

"I thought we should talk. Woman to woman." She tilted her head. "You look tired."

"Leave."

"In a moment." She reached into her cloak and produced a folded document. Cream-colored paper. Heavy. Official. Stamped with the imperial seal of the royal treasury. "I wanted you to see this."

She held it out. I didn’t take it.

"Two million gold coins," she said, reading my hesitation with obvious pleasure. "Deposited into my personal account from the imperial treasury. Kaelen arranged it personally." She turned the document so the seal caught the moonlight. "For the child. His child. He’s taking responsibility, Elara. Properly. Financially. Publicly."

The words landed like stones dropped into still water. Each one sending ripples through everything I thought I understood.

Two million.

For her.

For the baby.

"He came to me recently," Seraphine continued, her voice soft, almost kind. "He held my hand. He asked about the baby’s health. He wanted to know if I needed anything." She paused. "He was gentle, Elara. The way he used to be gentle with you, I imagine. Before you drove him away."

"You’re lying."

"Am I?" She gestured to the treasury note. "Two million gold coins don’t lie. The imperial seal doesn’t lie. He’s chosen, Elara. He’s chosen me and this child. I know that hurts. But dragging this out only makes it worse for everyone—especially those beautiful children upstairs who keep getting caught in the crossfire."

Something inside me—something that had been bending and bending and bending under the weight of so many months—snapped.

Clean. Final. Like a bone breaking.

I stepped closer. My voice dropped to a register I barely recognized.

"You want to know what I did tonight, Seraphine?"

Her smile faltered.

"I left him a separation letter. On his desk. Formal. Legal. Witnessed and binding." I let that sink in. Watched her eyes widen. "So congratulations. You win. The title, the crown, the bed—it’s all yours."

"I—"

"And congratulations on your little bastard." The word came out razor-sharp. "I hope it inherits its father’s eyes. Those beautiful, lying eyes."

Seraphine’s expression hardened. The mask of warmth dissolved. Beneath it—cold calculation. "You’ll regret this, Elara. You used to speak so proudly about your mate bond. Look where that naive belief got you. When you’re alone in this rotting house with nothing—"

"I’m done," I said. "Completely done. So take your pregnant ass, your two million gold coins, and your precious baby, and get away from me." I slammed the door in her face.
