Becoming Lailah: Married to my Twin Sister's Billionaire Husband-Chapter 126: The Shadow

MAILAH WOKE to whiskers in her face and a rhythmic purring that sounded like a small motor running directly against her cheek.

"Good morning to you too," she muttered, gently pushing the cat away.

The creature—she really needed to ask what Mrs. Baker had named it—merely blinked at her with amber eyes that held far too much judgment for something that had spent half the night licking its own behind.

Sunlight streamed through the windows, painting everything in shades of gold and honey.

For a moment, Mailah lay still, letting the events of last night wash over her.

Lucien appearing at her window with tea. Grayson’s barely controlled restraint. The kiss that had left her dizzy and wanting. And of course, the cat that had appointed itself moral guardian of the estate.

Her lips curved into a smile despite herself. Her life had become absolutely ridiculous.

The cat meowed—loudly, insistently—and pawed at her shoulder.

"Alright, alright," Mailah said, sitting up. "I’m getting up. Though I don’t remember signing up to be your personal servant."

The cat hopped off the bed with feline grace and trotted toward the door, pausing to look back at her expectantly.

"You’re not seriously expecting me to follow you, are you?" Mailah asked.

Another meow, more demanding this time.

"Fine," she sighed, throwing off the covers. "But if this is some elaborate prank, I’m going to be very annoyed."

She pulled on a robe over her pajamas and followed the cat into the hallway.

The estate was quiet in that particular way that suggested everyone else was already awake and going about their morning routines.

Mailah could smell coffee brewing somewhere below, and the faint sound of voices drifted up from the lower floors.

The cat led her down the grand staircase with surprising determination, its black tail held high like a flag. They passed the library, the sitting rooms, and finally arrived at Grayson’s private study.

The cat sat in front of the closed door and meowed again.

"I’m not just walking into his study uninvited," Mailah said. "That’s... that would be rude."

The cat looked at her with such withering disdain that Mailah actually felt judged.

"You’re a cat," she told it. "You don’t get to make me feel bad about boundaries."

Another meow, followed by the cat raising one paw and deliberately scratching at the door.

"Oh, for heaven’s sake," Mailah muttered, reaching for the handle. "If I get in trouble for this, I’m blaming you."

The door swung open to reveal Grayson sitting at an enormous mahogany desk, papers spread before him, his glasses perched on his nose in a way that made him look both scholarly and unfairly attractive.

He glanced up and his expression shifted from focused concentration to something warmer.

"Good morning," he said, his voice still slightly rough from sleep. "I see you’re with Shadow."

"Shadow?" Mailah repeated, looking down at the cat, which had already padded into the room and jumped onto Grayson’s desk with complete disregard for the papers it was walking across. "That’s what Mrs. Baker named it?"

"That’s what it named itself, according to her," Grayson replied, gently moving the cat aside before it could sit on what looked like important contracts. "Apparently it appeared in the kitchen three nights ago and refused to leave. Mrs. Baker insisted it had ’chosen us.’"

"Chosen us," Mailah echoed, moving further into the room. "Since when does Mrs. Baker believe in mystical cat selection?"

"Since this particular cat walked through the wards without triggering a single alarm," Grayson said dryly. "Which shouldn’t be possible for a normal animal."

Mailah paused mid-step. "Wait. You’re saying Shadow is supernatural?"

"I’m saying Shadow is suspicious," Grayson corrected. "But so far, the only thing it’s done is knock things over, demand food at inconvenient hours, and apparently act as an impromptu chaperone."

The memory of last night—of heat, laughter, and one very opinionated cat—still lingered in Mailah’s mind.

She couldn’t help but stare at Grayson. The morning light caught the edges of the frames, making him look like the world’s most dangerously handsome librarian.

Mailah tilted her head. "Do you actually need those?"

Grayson didn’t look up. "Need what?"

"The glasses." She stepped closer, crossing her arms. "I just figured demons had, you know, perfect vision. Supernaturally perfect."

That earned her a pause. His pen stopped moving.

He lifted his gaze slowly, eyes gleaming faintly behind the lenses. "Most of us do."

"So...?" she pressed, her tone teasing but curious. "Are you secretly farsighted, or is this your attempt at blending in with the mortals?"

Grayson hesitated—just for a moment. Then he set the pen down and leaned back in his chair. "I’m conserving energy."

Mailah blinked. "Energy?"

He nodded once. "Every little use of power adds up. Sight adjustment, aura masking, ward maintenance—it all drains the same well."

Her teasing smile faltered as realization dawned. "You’re saving it," she said quietly. "Because if you save enough..."

He didn’t answer. He didn’t have to.

Mailah’s voice softened. "Then you don’t have to feed yet."

His expression gave her confirmation more honest than words.

The air between them shifted—less playful now, but charged with something else entirely.

Concern. Understanding. A trace of tenderness she hadn’t expected.

"Grayson," she murmured, stepping closer to the desk. "How long have you been doing that?"

He gave a small, dismissive shrug. "Long enough to make your observation impressive but not enough to be concerning."

"That sounds exactly like something concerning," she said, narrowing her eyes.

He smiled faintly. "You worry too much."

"Maybe because you don’t worry enough."

That earned a low chuckle from him—the kind that softened the edges of his usual stoicism. "I assure you, I worry quite adequately."

"Mm-hm," she said, unconvinced. "You’re sitting there pretending to be human with your cute glasses, trying not to drain your power, and you think that’s normal?"

"Cute?" he repeated, a spark of amusement flickering in his gaze.

She rolled her eyes. "Don’t make me take it back."

Too late—he was already smiling. "Noted."

At that exact moment, Shadow, the resident cat, leapt onto the desk and strutted right across his papers, tail flicking like a metronome of judgment.

Mailah smirked. "Your assistant’s here."

Grayson sighed. "She has terrible timing."

"Must run in the house," Mailah quipped.

His laugh—low and reluctant—was worth every ounce of teasing.

Shadow chose that moment to meow loudly and paw at a stack of papers, sending several sheets fluttering to the floor.

"And you," Grayson said to the cat, "are becoming increasingly suspicious."

As if in response, Shadow’s form seemed to shimmer for just a moment—a flicker of something not quite feline, not quite solid—before resolving back into ordinary cat shape.

Mailah’s eyes widened. "Did you see—"

"Yes," Grayson said grimly. "Which confirms my theory that this is not actually a cat."

"Then what is it?"

"A familiar, most likely," a new voice said from the doorway.

They both turned to find Lucien leaning against the doorframe, looking far too pleased with himself.

He’d changed since last night—gone was the casual elegance, replaced by what could only be described as business angel attire. Dark slacks, crisp white shirt, silver cufflinks that caught the light.

He looked like he was about to close a deal or smite someone, possibly both.

"A familiar," Mailah repeated. "As in, a witch’s familiar?"

"Or a guardian’s," Lucien replied, stepping into the room uninvited. "Or in this case, probably sent by someone who wants to keep an eye on the estate without being obvious about it."

Grayson’s expression darkened. "Who?"

"That’s the interesting question, isn’t it?" Lucien moved to the bookshelf, running his fingers along the spines with casual interest. "Could be someone friendly, making sure you survived the anniversary fallout. Could be someone less friendly, gathering intelligence on your new domestic arrangement."

He glanced at Mailah with that knowing smile that suggested he saw far too much. "Or could be someone who’s simply curious about the human who’s managed to domesticate the most isolated demon in existence."

"I haven’t domesticated anyone," Mailah protested.

"You got him to ride a bus," Lucien pointed out. "That’s basically the same thing."

Grayson stood, moving around the desk with predatory grace. "If you know who sent the familiar, stop being cryptic and tell me."

"But where’s the fun in that?" Lucien’s smile was all teeth and mischief. "Besides, I genuinely don’t know. The magical signature is... obscured. Deliberately so. Whoever sent it is skilled enough to hide their tracks."

Shadow—or whatever it actually was—sat on the desk and began grooming itself, apparently unconcerned by the revelation of its true nature.

"So we have a supernatural spy living in our house," Mailah said slowly, trying to process this. "And we’re just... okay with this?"

"We’re monitoring it," Grayson corrected. "There’s a difference. If it makes any hostile moves, I’ll deal with it. But so far, it seems content to knock things over and interrupt intimate moments."

Lucien’s laugh was delighted. "Oh, I heard about that. Mrs. Baker mentioned something about Shadow having impeccable timing."

"Mrs. Baker talks too much," Grayson muttered.

"Mrs. Baker is a treasure," Lucien countered. "And she’s worried about you, though she’d never admit it. The whole household is. You’ve changed since..." He gestured vaguely at Mailah. "Since she arrived."

"Changed how?" Mailah asked, genuinely curious.

Lucien considered her question seriously. "You’re more grounded. More... present. For centuries, you’ve been going through the motions of existence without actually living. Now you’re investing in things. People. Feelings you spent lifetimes avoiding."

Something flickered across Grayson’s face—vulnerability quickly masked. "And you’re telling me this because?"

"Because change makes you a target," Lucien said bluntly. "And I’d rather you be aware of how visible you’ve become. The supernatural community is watching, Grayson. Some with approval, many with concern, a few with outright hostility."

The lightness that had filled the morning evaporated, replaced by cold reality.

Mailah felt it settle over her shoulders like a weight—the reminder that their happiness existed in a bubble that could burst at any moment.

"Varrow," she said quietly.

"Among others," Lucien confirmed. "The collective he’s building isn’t just about pain-feeding. It’s about establishing a hierarchy—demons above humans, with strict controls on any relationships that might blur those lines."

"And our engagement," Grayson said, "directly challenges that hierarchy."

"Your entire relationship challenges it," Lucien corrected. "You’ve taken a human as an equal partner, publicly defended her choices, granted protection rights that undermine demon authority over their ’property.’ You’ve essentially declared war on a system that’s existed for millennia."

Mailah’s hand found Grayson’s, threading their fingers together. "So what do we do?"

"You prepare," Lucien said simply. "You strengthen your defenses, call in favors, and make alliances with those who believe in what you’re trying to build. And you accept that there will be a reckoning—probably sooner rather than later."

"Cheerful," Mailah said.

"Realistic," Lucien replied. "But not without hope. You have more support than you know. Dr. Morrison, for one. He’s been healing victims of the collective for years—he’ll back any play you make against them. And your brothers," he said to Grayson, "are less united in their opposition than you might think."

"My brothers are opportunists," Grayson said flatly.

"Your brothers are complicated," Lucien corrected. "Carson especially. His involvement with the collective isn’t what you assume."

Before Grayson could respond, a sharp crack split the air—the sound of magical wards being triggered.

All three of them moved at once, Grayson toward the window, Lucien toward the door, Mailah frozen between them as adrenaline flooded her system.

"What was that?" she asked, though she already knew it wasn’t anything good.

Grayson’s expression had gone hard and cold, every trace of the man who’d kissed her last night vanishing beneath the demon who’d survived centuries of supernatural politics.

"Someone just breached the outer perimeter."
