Became Pregnant With the Demon King’s Child

The morning had been manageable. As long as Lowell didn’t consciously think about the fact that Felix was away, it didn’t feel that different from usual. The problem began in the afternoon. Around three o’clock, Lowell’s hand, which had been flipping through pages, began to slow—and by four, it had stopped entirely.

Felix was away from the castle not long ago, and I didn’t react this sensitively then. Is it just because I don’t have anything particular to do right now? Or is it because I’m aware that he’s physically far away, and my hormones are responding?
Realizing he couldn’t concentrate due to the unease, Lowell began organizing his books and documents.
“Shall we return to the tower?”

Deciding it was better to rest than to do nothing, he headed back earlier than usual. Once he arrived, walking slowly all the way, his eyes immediately settled on the magic sphere Felix had left behind.
“Please relax. We’ll notify you when a message comes through.”
Tia, having noticed, spoke with consideration—but Lowell’s waiting didn’t end. As the sun disappeared behind the snowy mountains, it became increasingly difficult to keep his limbs still.

It’s about time for a message…
Even as his eyes grew heavy from fatigue, tension continued to settle into his body. Instinctively, Lowell wrapped himself tightly in the blanket and inhaled the lingering scent of Felix’s pheromones. He didn’t realize it, but it was an unconscious attempt to lower his tension levels.
When full darkness had fallen and Lowell was dozing off and startling awake over and over, the magic sphere finally began to glow.

“Young master.”
At Karisse’s call, Lowell leapt out of bed without hesitation. He nearly tripped on the blanket but managed to catch himself and sit at the table.
But the face that appeared in the glowing sphere wasn’t the one he’d been desperately waiting for. The figure was smaller in build, and more than anything, had light brown hair and eyes—the most common coloring. Yet Lowell had no trouble recognizing the man as Felix. The unabashed, possessive gaze and restrained posture were unmistakable.

“Your Grace.”
When Lowell called out without hesitation, Felix raised one eyebrow.
—How did you know?

“Just did.”
The moment he saw Felix’s face looking perfectly fine, the tension that had knotted inside Lowell’s chest finally unraveled. The ache in his fingertips, taut with anxiety, loosened; the pressure in his belly eased. Only after that faint discomfort disappeared did his rational mind return. He finally understood the true nature of the unease that had blended so seamlessly with his longing.
I was worried.

Lowell knew that the Crown Prince wasn’t an idiot—he would’ve arranged a safe route to meet Felix. But the heart didn’t always follow reason. Deep down, he had been afraid that Felix might walk into a trap or that something might go wrong.
Disaster always comes out of nowhere.
That was a lesson left behind by the farewell Eunoh had once lived through. A flash of his parents’ funeral crossed Lowell’s mind, but he shook his head to chase it away.
Damn trauma.

Whenever someone he loved went somewhere even slightly dangerous, his anxiety spiked.
—Did something happen?
Felix frowned and leaned closer to the sphere when Lowell stayed silent, a bitter expression on his face. Then he pressed his fingers to his forehead to smooth the wrinkle—a clear recall of what Lowell had once told him.

At that sight, Lowell felt the heavy fog of gloom suddenly lift.
Focus on the moment.
He looked more closely at Felix’s appearance.

“No, nothing happened. By the way, is that transformation magic?”
—It’s called polymorph.
“Polymorph?”

—It’s a type of shape-shifting spell. It takes a lot of mana, so it’s not something you use lightly, but I had to pass through a city today—so it was necessary.
When Lowell looked confused by the short reply, Felix kindly explained further. Everyone present, except Lowell, ◆ Nоvеlіgһt ◆ (Only on Nоvеlіgһt) knew he wouldn’t have bothered to explain like this for anyone else.
“It’s completely convincing.”

—That’s the point of the spell.
Despite having used a very difficult spell, Felix answered as casually as always, like it was no big deal.
“Have you eaten?”

—Yes.
The brief answer might’ve ended the conversation, but Lowell had long grown skilled at coaxing longer replies from him.
“It must’ve been hard to eat while traveling. And your stomach still hasn’t fully settled.”

—Thanks to the ring you gave me, I’ve been fine so far.
Lowell couldn’t tell if that was sincere or just words, since he wasn’t there to see it—but the words alone were enough to satisfy him. When Lowell smiled brightly, Felix’s eyes stayed fixed on his face. The two acted as if no one else existed, and the knights standing nearby pretended not to hear their conversation.
“I’m glad. Will you be on the move again tomorrow?”

—I need to find someone here first. After that, I’ll decide whether to move on or stay a bit longer.
“You’re not too tired?”
—As if this would tire me. You, maybe, with your stamina.

“Still, it was a long journey. Did anything happen on the way?”
Felix parted his lips, then looked as though he’d made up his mind about something and opened his eyes slightly wider.
—After splitting from the knights and entering the village… I saw a cat.

The sudden change in topic made Lowell perk up.
Was the cat related to something important? Maybe it delivered a message?
—It looked like you.

The rest of the sentence made Lowell, who had been resting his chin in his hand, lose balance and nearly fall over.
—Are you all right?
“W-what? Ah, yes, I’m fine.”

Lowell never imagined he’d be told he resembled a cat. He rubbed the back of his neck. They had agreed to share trivial stories before parting—but this kind of sweet, couple-like remark without warning? It felt like cheating.
Whether Lowell flailed or not, Felix continued.
—It was a yellow cat. Its fur sparkled in the sunlight. Its tail stood straight up, and it yawned—its fangs were sharp, just like yours.

“I’ve never heard that before.”
—From anyone?
When Felix asked with surprise, Lowell almost replied that he was being delusional—but settled for a quiet, “No.”

—They’ve all got poor taste, then.
“I stopped by the greenhouse today. By the time you return, it’ll probably be fully restored. I want to see it with you.”
—Okay.

They were about to continue with more idle conversation when a knock came from behind Felix. A knight’s voice called, “Lord Rick,” suggesting there was a message to deliver.
“I guess that’s it for today.”
—Yeah. We’ll talk again tomorrow.

Felix, who had been rising to stand, paused and bent slightly at the waist. Even though they’d agreed to end the call, Lowell remained seated.
—There’s nothing you need to worry about. I’ve made sure even the worst-case scenarios are covered. So don’t make that face.
When he bent forward, Lowell caught a glimpse of the chain around his neck. It was the necklace Lowell had given him.

“I believe you.”
Astonishingly, his heart settled at once. The anxiety that had ruled his day sank below the surface like it had never been there.
***

After that first day, Lowell’s mood improved significantly. During the day, he wandered around the estate or sorted out matters and concerns for the future in the study. At night, he still waited for Felix’s messages, but he no longer felt so anxious he couldn’t function. He believed in Felix, who always showed up on time, promising safety.
Things went off track on the sixth day after Felix had left the castle.
—It looks like I’ll be later than expected.

“How much later?”
—It might take up to ten days.
“Nothing went wrong, did it?”

—Our side’s fine. One of their key figures was injured while fighting monsters.
From that short reply, Lowell was sure—it was the Crown Prince’s partner, the original protagonist of this novel, who had been hurt.
I thought with Felix’s decision, nothing would go wrong.

It was a frustrating situation. If his guess was right, the delay wouldn’t just be a few more days—it might be much longer.
“I hope it’s not a serious injury.”
—Yeah.

After ending the short call, Lowell sat by the window and gazed at the moon, which was more than twice the size of the one in his original world. Tonight, it shone especially bright, making the surrounding stars hard to see. Hugging his knees, Lowell fiddled with the obsidian jewel that resembled the night sky. It was going to be a long night.
And just as Lowell feared, the next day Felix said the delay might be two more days. The day after that, he said it could take another three. The extended trip finally came to an end only after fifteen full days had passed.
