Became Pregnant With the Demon King’s Child

“Was there such a place in the castle?”

“It’s the Mage Tower. It wasn’t a place I used often, but I’ve made it cozy, so it should be livable. If there’s anything lacking, don’t hesitate to say so.”
The Mage Tower was located at the far left end of the castle. Lowell had never taken an interest in it, not knowing its use. Judging the distance by glancing out the window, he tapped lightly on the window frame with his finger.
It feels too far from the main building. Wouldn’t it be inconvenient to go back and forth?

There was no burden in simply staying in the room—since it was cozy enough. But Lowell needed to take walks for exercise and occasionally check on the castle, so he had to visit the main building at least once a day. With his body gradually becoming heavier, this tower’s location felt more burdensome than his usual study.
But it’s clear he went to a lot of trouble, so I can’t just reject it outright.
As Lowell pondered how to express his thoughts, Felix began setting dishes brought by a servant onto the table one by one. Though the table was quite large, it was quickly filled to the brim.

“We could eat in the dining hall, you know.”
“The dining hall’s too far. From now on, I’ll have meals prepared here.”
As Lowell sat down on the chair Felix pulled out for him, a sense of suspicion deepened.

Something’s definitely off. He’s basically saying I’ll be eating here from now on. And since he said the dining hall is far, it means he’s aware that this place is a fair distance from the main building. Then why choose here, of all places?
When Lowell didn’t move his fork and knife, Felix brought food directly to his mouth. Like a baby bird accepting food, Lowell hurriedly grabbed his own fork, signaling that he would eat by himself.
“I noticed before—you really like roast quail.”

Even so, Felix didn’t stop. Though the food scent seemed to overwhelm him at times and he occasionally covered his mouth, he continued placing deboned meat onto Lowell’s plate. The rate at which he deboned outpaced the rate Lowell could eat, causing the meat to pile up like a tower. It was so natural it didn’t even seem intentional.
He’s never waited on anyone before in his life.
Felix, meanwhile, had only eaten a few bites of apple salad. As Lowell busily chewed, he took a sip of tomato juice and asked carefully,

“You still can’t eat properly?”
Looking at Felix’s pale face, he hadn’t needed to ask.
“That’s not something you need to worry about, Lowell. Just take care of your own body.”

His answer had a sharpness to it, as if drawing a boundary. Lowell’s brow furrowed slightly at the sense of dissonance. The sudden creation of this room was one thing, but Felix’s attitude also felt strange. And after the meal, no servants came in—Felix himself placed the dishes on the trolley and wheeled it out of the room.
I need to sit down and talk to him properly.
But that wish wasn’t granted. The moment the meal was over, Felix got up and left before Lowell could even react.
“It’s time to spar with the knights. I’ll be back soon.”

Felix opened the door, allowed the knights inside, then exited the room. Left frowning with arms crossed, Lowell eventually couldn’t take it and approached Caris and Tia.
“Tia, # Nоvеlight # do you happen to know why His Grace brought me here?”
“That’s not something I can answer.”

Tia gave an unmistakably troubled look. Feeling frustrated, Lowell headed for the door, deciding he might as well inspect the castle. But even that was blocked by Caris.
“I’m sorry.”
Caris stood in his path with a stern expression.

Wait. Am I... being locked up right now?
“Please step aside.”
Despite Lowell’s request, they didn’t move.

“I’m not just asking this time. That was a command.”
Implying this was no longer a suggestion but an order, the two hesitated and took a step back.
If Felix had ordered them to stop me from leaving, they wouldn’t back off this easily... Lowell thought, but he acted first. He pushed the door—only for nothing to happen. Not that “nothing happened” as in there was no reaction from the people around, but quite literally, the door didn’t budge.

What the...
He pushed again with more force, but the door remained immovable. All that came from it was drained energy and labored breath. Staggering back to the sofa, Lowell looked up and asked Caris,
“Am I... being locked up right now?”

“That’s not something I can answer.”
Lowell felt an urge to beat on his own chest from the frustration welling up.
What the hell is going on? Just yesterday I was tidying up the castle, and Felix was saying I could do whatever I wanted!

As he tried to understand this sudden shift, a bolt of realization struck him.
The note.
The very note he’d meant to talk about when he woke up.

If he thinks I was hiding it, then I guess it’s something he could misunderstand...
Reclining on the wide sofa, Lowell let out a sigh of certainty. There was no other reason Felix would suddenly do an about-face and lock him away like this.
But still... isn’t it too much to imprison me without even letting me explain? I really thought we’d built some trust...

His mouth tasted bitter.

“Your Grace, why did you lock me up?”

Lowell asked Felix directly when he returned that evening. Felix’s hands, in the middle of removing his coat, paused briefly.
“I didn’t lock you up—I only meant to protect you.”
“You sealed off the tower so I couldn’t leave. How is that not confinement?”

“You can leave if you’re with me, so it can’t be considered imprisonment. If you’re frustrated, just say so.”
To say it wasn’t confinement simply because he couldn’t leave alone—Lowell found it ridiculous.
“Did you see the note?”

Lowell asked cautiously. Felix didn’t answer, but he also didn’t ask, what note?—which was already more than enough of an answer for Lowell.
“That note was—”
Just as Lowell opened his mouth to explain, Felix suddenly leaned in until his face filled Lowell’s vision.

“May I kiss you?”
“We were in the middle of another conversation.”
After realizing he’d been locked in, Lowell had made a firm decision: he wouldn’t allow physical intimacy unless a real relationship of trust had been built.

“So I can’t?”
The young man gazing down at him looked desperate. For a moment, Lowell saw a large dog waiting for its master’s command superimposed over Felix’s face. It was as if he could hear the sound of his previous resolution crumbling in real time.
A kiss should be fine… it’s just a way of expressing affection...

The very fact that he considered it an excuse meant he’d already lost. His head was already filled with Felix’s yearning expression.
“N-no… it’s not like you can’t...”
The moment permission was granted, Felix leaned in.

His heated breath poured into Lowell’s mouth like someone who had just finished a long-distance sprint. Without even time to catch his breath, Felix’s thick tongue swept inside, tangling with his. Lowell had meant to explain, but now all he could do was open his mouth and accept him.
“Nnngh…”
Lowell let out a faint moan as he tapped Felix’s shoulder, overwhelmed by the intensity. This kind of forceful intimacy wasn’t his style, and he intended to push Felix back to slow things down. But once separated, Felix only became more eager, drawing Lowell’s tongue deeper into his mouth.

Then he lightly bit down on Lowell’s tongue. It wasn’t enough to hurt, but it was deliberate—like he wanted to leave a mark. As Lowell submitted, Felix slowly soothed the spot with his tongue, almost apologetically. It felt like every inch of his tongue was being played with.
“Lowell.”
When their mouths finally parted, Felix whispered his name in a low voice.

“Felix.”
Lowell answered, and the fire reignited in Felix’s eyes as he kissed him again. That heavy tongue scraped against his palate and pressed hard. What started as a juvenile kiss deepened into something thick and intense. Feeling the heat rise in his belly, Lowell closed his eyes and knit his brow.
Felix watched every expression Lowell made and wrapped an arm around his waist. Their shared warmth brought beads of sweat to their chins.

No. If this keeps going, we’ll end up in bed. And there’s still so much we need to talk about.
Feeling it was getting out of hand, Lowell genuinely pushed Felix away. Rather than looking disappointed, Felix seemed relieved by the restraint—turning his head aside.
“R-right… let’s go back to the note. If you locked me up because of it—”

Coming back to his senses, Lowell realized Felix had deliberately avoided the conversation, and brought it up again. But before he could finish, Felix interrupted him.
“Keeping you here has nothing to do with that note.”
Felix said in a low, hoarse voice. His tone was more firm than Lowell expected—and the direction of the conversation was going someplace entirely unanticipated. If Felix had gotten angry over the secret note, Lowell could’ve at least understood. But instead, he had chosen evasion.

“Then why…?”
“I told you—it’s for protection.”
“Then you’re not saying you suspected me because of the note?”

Lowell had been sure of that. Even if Felix loved him, he knew Felix didn’t fully trust him. That was only half a love. As Felix tapped the hilt of his sword with his finger, he finally spoke.
“The paper that note was written on… belongs to the Imperial family.”
