And just like that, he vanished again, leaving the scent of rain and the echo of two heartbeats pounding in the dark.
—-----------------
The nights grew heavier after that.
Every time Iris closed her eyes, she dreamed of heartbeats, his and hers racing together, then faltering apart. When she woke, her hands were cold and her skin pale. At first, she told herself it was lack of sleep but when she passed a mirror one morning, she froze. Her reflection was fading, not gone, but dim, like a photograph losing its color. She didn’t need a stethoscope to know what it meant.
The bond was stealing her life.
That evening, she found him waiting outside the hospital, Arden, silent beneath the streetlights, coat dark with rain. He looked weaker too; his eyes had lost their unnatural glow. Still, he smiled when he saw her, soft and painful at once.
“You look pale,” he murmured.
“You should see yourself,” she said. “You look… human.”
He gave a quiet laugh. “That’s not as comforting as it should be.” They walked without speaking, the rain drizzling around them. When they reached the small chapel behind the hospital, he stopped.
“This place feels safe,” he said, running a hand along the cracked stone walls. “Maybe because no one believes in anything sacred anymore.”
Iris turned to him. “Lucia said every heartbeat I give you feeds the curse. But you feel alive again. Isn’t that worth something?” He looked away. “It’s worth you. And that’s what terrifies me.”
“Why?” She asked.
“Because I’d trade eternity for one more heartbeat with you,” he said quietly. “And that’s the curse I can’t escape.” Her throat tightened.
“Then don’t fight it.”
He shook his head. “You don’t understand, Iris. The more I love you, the faster I fade. My kind aren’t meant to feel. Every emotion you awaken takes a decade from me.” She stepped closer. “Then let it. What’s eternity without love?”
His expression softened, fear and longing wrestling behind his eyes. “You speak like light, and I’ve lived too long in the shadows.” He brushed her cheek with his thumb, and her world tilted. Her knees weakened; her pulse staggered. He caught her before she fell, holding her close, desperate.
“You see?” he whispered. “You’re dying for me.” Her lips trembled. “Then stop pretending you don’t want this.”
He lowered his forehead to hers. “Wanting isn’t the same as deserving.”
Their heartbeats collided, one strong, one faltering and for a moment, time stood still.
Then, just as suddenly, he pulled away.
“I won’t let you die for me,” he said, voice breaking. “Even if it means forgetting what love feels like.”
“Arden…” He was already gone.
The chapel fell silent except for her breathing and the faintest echo of his voice lingering in her chest.

Dr. Marrin, an obsessed scientist and Iris' mentor, watched Iris through the glass wall of the lab.
She looked thinner, paler, distracted with a heart beating out of rhythm with the world.
He’d noticed the change weeks ago. At first, he blamed exhaustion. Now, as she handled vials that faintly glowed under the sterile light, he knew it was something else. Something he couldn’t explain yet. When she left, he stepped inside, eyes narrowing at the faint traces of silver luminescence on the table. Blood. But not human.
He smiled. “So that’s your secret.”

That night, Iris returned home to find the door slightly ajar.
Her chest tightened. “Arden?” No answer. Only the soft creak of floorboards. She stepped inside, heart hammering. A shadow moved by the window.
“Lucia?” she whispered.
“Not quite,” said a voice behind her.
Dr. Marrin emerged from the dark, holding the glowing vial between two fingers.
“Fascinating, isn’t it? Living blood. It somehow reacts to your heartbeat.”
She backed away. “You went through my lab?”
He smiled calmly. “Science demands curiosity. And yours, your miracle, deserves to be studied.”
“That’s not a miracle,” she said. “It’s a person.” “Is it?” he asked, his eyes gleaming. “Because I ran a test, Iris. No human cell behaves like this.
Whatever you’re protecting, it isn’t a man. It’s a specimen, now pray tell.”
She shook her head. “You don’t understand. He’s…”
“Dead,” Marrin interrupted. “Or something close enough.” Lightning flashed, illuminating his face. For a second, she saw obsession there, hungry, righteous. “You’ve always wanted to understand death,” he said softly.
“Now you can watch it obey your heartbeat.” A gust of wind burst through the window, scattering papers and dust. And then Arden was there, materializing between them, eyes burning silver.
“Step away from her,” he said, voice low and lethal.
Marrin froze. “Impossible…” Arden’s gaze hardened.
“You meddle in forces you can’t define and handle.” The doctor raised a syringe, hands shaking.
“Maybe not. But I can contain them.” He lunged. The syringe never reached its mark. Arden’s hand closed around it, glass shattering.
Blood — his blood — splattered across the tiles, glowing brighter than fire.
Marrin stumbled back. “You bleed light?…” Arden didn’t answer. He turned to Iris. “Go. Now.”
But Lucia’s voice came from the doorway. “No one leaves.” Her presence chilled the room. She stood in the rain-soaked frame, eyes sharp with fury. “He warned you, Iris. You never listen.”
“Lucia… please,” Arden said. “Don’t do this.” “I’m saving you,” she whispered. “Before love kills us all.” She moved faster than sight. The world blurred, cold hands, broken glass, a scream that didn’t sound human.
Then silence.
When Iris opened her eyes, the lab was burning with pale fire.
Lucia was gone. Marrin lay unconscious. Arden stood beside her, the glow of his blood fading.
“I told you,” he said, voice raw. “Every time I feel, the world seems to break.” She reached for him, tears mixing with the rain blowing through the shattered window.
“Then let it break,” she whispered. “As long as you’re still here when it does.”

Smoke drifted from the shattered lab, glowing faintly blue where Arden’s blood had burned through the tiles.
“I can’t leave him,” Iris said, glancing at Dr. Marrin’s still on the ground.
“You can,” Arden replied. His voice shook, not from fear, but from exhaustion. “He’ll live. For now.” Lucia’s attack had vanished with the storm, leaving only silence and the throb of sirens far away.
Arden swayed; Iris caught his arm. His skin was warmer than before, his pulse faint but human.
“You’re bleeding again.” She said, He smiled weakly. “You’re getting better at noticing.” They slipped into the alley behind the hospital, rain masking their footsteps. The city lights flickered as if the world itself held its breath.
“Where will we go?” she asked.
“Somewhere the sun can’t find us,” he said. “For tonight, that will have to be enough.”
He stumbled; she pressed her palm to his chest. The heartbeat beneath it was fragile, uncertain. It frightened her, how much of it felt like her own.
“Every time you bleed,” she said, “I feel it.”
“I know.” He met her gaze, eyes soft. “We’re the same wound now.”
They walked in silence until they reached the river. The bridge where they had first met loomed ahead, wet stone gleaming under the lamps.
“Full circle,” she whispered.
