Chapter 117: Romantic Quests and Other System Malfunctions

As the night wore on, the four parted ways under the quiet gaze of the stars. The dragon had been the last to leave, lifting into the sky with wings of shimmering green fire, offering only a cryptic farewell:

’I’ll return tomorrow. Be ready.’

No explanation. Just the wind and the shimmer of scales vanishing into the clouds.

"Well, that was sure fun..." Marcus muttered to himself, the weight of fatigue settling into his limbs as he crossed the cobbled street alone. The city, once alive with festival lights and chatter, now lay blanketed in gentle stillness.

His footsteps echoed lightly against the ground as he approached the front gates of his estate—tall wrought iron framed by cold stone pillars. And there, waiting, was a familiar and mildly terrifying figure.

Aveline.

She stood dead-center in front of the gate, arms crossed, one foot tapping rhythmically against the ground. Her black hair shimmered faintly under the moonlight, but it was the pout—and the glare in her dark eyes—that cut through the air like a dagger.

"Came to greet your charming older brother?" Marcus said, smirking.

"Shut up," Aveline snapped. "I heard you solved the myth."

Her voice was tight, sharp with restrained irritation.

"What’s it to you?" Marcus replied casually, already knowing where this was going.

"Huh...? It was supposed to be my project, remember?" she said, stepping forward with fire in her voice. "Now I need to find something else to investigate."

She paused. Her tone dropped lower. Dangerous.

"Or, of course, you could tell me everything about the myth. And I might consider not splitting your skull in two."

She was half-joking. Probably.

Marcus raised an eyebrow, unimpressed by the threat but smart enough not to test it. "Fine. But don’t blame me when it’s underwhelming. Honestly? It’s fifty-fifty."

He moved past her, pushing open the iron gate with a metallic groan.

"You’re making no sense." Aveline followed with a frown.

"Well," Marcus said with a crooked grin, "you’re about to understand."

They stepped into the estate together, the heavy gate clicking shut behind them. The cool night air gave way to the soft warmth of the foyer, where the floor absorbed their steps and chandeliers painted the hallway in flickering amber light.

As they made their way up the stairs, Marcus paused, a thought creeping into his mind.

"Hey, sis," he said, glancing back.

"What?" she replied, climbing the steps a few feet behind him.

"Are Mom and Dad home yet?"

"No," Aveline sighed. "I heard they’re gonna be stuck at work for a while. Something about tracking an extremist mage group in the city."

Marcus stopped. His brows drew together.

"You think it’s connected?"

She met his eyes.

"Yeah. Probably tied to the masked figure we met last night."

Their pace slowed as they turned the corner onto the second-floor hallway. Marcus scratched the back of his neck, thoughtful.

"Aren’t you worried at all?"

Aveline shrugged, lifting a hand lazily. "Not really. If we managed to beat one of those guys, Mom and Dad can definitely handle a few more."

Marcus chuckled, the tension easing from his shoulders. "Fair point."

They reached his room. The door creaked slightly as he pushed it open, revealing a mess of books, clothes, and various magical artifacts scattered in organized chaos.

Inside, Marcus launched into a full rundown.

He recounted everything—the myth, the Archmage’s sudden appearance, the way the waterfall opened, the masked figure who reappeared with ominous timing. Then came the dragon: its presence, its power, and the pact now pulsing inside Marcus like coiled heat.

Aveline sat on the floor in the corner of the room, legs tucked under her, brows furrowed in concentration.

"All that happened... today?" she asked slowly, disbelief dripping from every syllable.

"Yeah," Marcus replied, lounging on the edge of his bed, arms stretching above his head. "Nothing out of the ordinary."

"I beg to disagree."

"Then beg."

His smirk didn’t last long—Aveline stood, grabbed the thickest book she could reach from his shelf, and launched it at his face.

"Aghhh—!" Marcus flinched as it hit him squarely in the forehead, the thump echoing across the room.

"Watch yourself..." Aveline muttered, brushing invisible dust from her hands.

But before Marcus could retaliate with a pillow—or another terrible joke—a soft chime echoed through the house. The bell. Dinner time.

Aveline was already on her feet, heading for the door. She paused in the frame and glanced over her shoulder.

"But seriously," she said, her voice softer, "please be careful."

Marcus blinked. "What’s with the sudden soft side—"

Click.

She shut the door before he could finish.

He exhaled, rubbing the sore spot on his forehead.

"Siblings... still not used to them," he mumbled, rising from the bed and stretching with a groan. Joints popped. Muscles ached. Magic thrummed somewhere under his skin.

He crossed the room to the door, placing his hand on the knob, but paused.

A quiet thought flickered in the back of his mind.

"Tomorrow is my fourth day in this world... and all in all, I can’t complain."

Another thought followed, sharper.

’I should check my system again... I’ve been ignoring it too long. Figured I didn’t need it—but that was then.’

’Also the quest... It never updated it. I should look at that tonight.’

He opened the door and stepped into the hallway, the soft scent of spices wafting up from the dining room below.

Tomorrow promised more mystery. More danger.

But tonight, at least for a little while, he could afford to breathe.

Dinner passed uneventfully.

Which, after the chaos of the day, was a small miracle in itself.

Marcus returned to his room with a satisfied groan, unbuttoning his shirt one-handed, only now realizing he had completely forgotten to change out of his uniform before heading down to eat. The fancy collar clung to him with a strange mix of sweat and lingering dust.

"I think I may have eaten too much..." he muttered, patting his stomach.

First a mythical feast with a serpentine dragon spirit—then a full-course family dinner.

"From that dragon banquet to this... I’m definitely gonna sleep like a corpse."

After changing quickly into something more comfortable, he collapsed at the edge of his bed. The mattress creaked under him, welcoming his weight. The soft glow of the moonlight spilled in through his window, casting silver streaks across the floor.

And then, with a breath, he uttered the familiar word.

’System.’

A soft chime echoed in his mind. A glowing panel blinked into existence before his eyes, its golden text hovering gently in the air.

[Quest: Myth of the Three Fates – "Romantic Entanglements Unlocked"]

Marcus blinked.

"Huh. Still no update on the affection stuff either... This must be what’s been clogging it up."

He leaned forward, elbows on his knees, fingers laced together in thought. The screen hung silently in front of him, almost smug in its lack of guidance.

Most of his previous quests had come with detailed breakdowns. Conditions, rewards, progress bars. This?

This one was just... a title.

He already had a hunch it involved Victoria and Cynthia. Too many coincidences, too many strange interactions.

But assumptions weren’t the same as confirmation. And the last thing he needed was to accidentally ruin things by diving headfirst without context.

"Victoria definitely knew more about this quest than I did..." Marcus murmured.

Then another thought flickered through his mind. A frustrating realization.

In his previous life, he’d rarely read LitRPG novels or system-based comics. He’d always skimmed past them, more drawn to raw fantasy or gritty post-apocalypse. So now, tossed into a world with a literal functioning system, he was practically flying blind.

Still.

Better to experiment than sit in the dark.

"Uhh... quest details?" he said, hesitating.

The system blinked again.

[Quest: Myth of the Three Fates – "Romantic Entanglements Unlocked"]

Condition: Establish a relationship with both Victoria and Cynthia simultaneously.

Optional Condition: Ensure both parties are aware of, and agree to, the situation.

"...Huh."

Marcus tilted his head slowly.

"Seriously...? That’s it?"

His eye twitched slightly.

"It’s literally the same old format—it just refuses to spoon-feed me unless I ask?"

A wave of irritation crept up his spine.

"Is this thing updating in real time now?!"

Before he could get any more worked up, a sudden knock echoed against the door. Sharp. Annoyed. Familiar.

Aveline’s voice pierced through the wood.

"Can you quiet down?!"

Marcus sighed.

"Go to bed already," he shot back lazily.

"Then lower your voice," she snapped, before her footsteps trailed off down the hallway.

The silence returned.

Marcus stared at the glowing quest screen for a while, then dismissed it with a flick of his hand. The room dimmed again, the only light now the silver cast of the moon.

He lay back, arms behind his head, eyes on the ceiling.

"I already suspected this... but seeing it spelled out like that hits different," he said quietly, a dry laugh escaping his lips.

"I figured I could coast through this quest passively and naturally... but with some of my other systems acting up ever since it activated, maybe it’s time I start taking it seriously."

He sighed again, deeper this time.

Sleep crept in at the edges of his vision. But his thoughts remained tangled in the web of conspiracies, dragons, and now—romantic complications written into fate itself.
