Bound By The Billionaire’s Rules

The Brother

A week into her contract, Sera had developed a routine of sorts. Breakfast with Noemi at seven, mornings spent in the estate’s smaller library pretending to read while actually cataloguing every door, every camera, every place the west wing corridor might connect to the rest of the house. Afternoons were her own, technically, though Orion’s security team seemed to know exactly where she was at all times regardless of whether she notified them.

It was on the eighth day that she met Lucien Vale.

She was in the east garden, the one Mireille had told her was safe to walk in, cutting flowers for the kitchen at Mireille’s request, when a voice behind her said, “You must be the mystery woman my brother locked in his house.”

Sera turned to find a man leaning against the garden wall with the kind of ease that suggested he’d never once worried about anything in his life. He had Caius’s height, Caius’s dark hair, but none of his brother’s stillness. His face moved constantly, amusement flickering across it like weather.

“I’m not locked in,” Sera said. “I signed a contract.”

“Sure you did.” Lucien pushed off the wall and approached with the loose, easy walk of someone who had never had to earn a room’s attention, because he’d always simply had it. “Lucien Vale. Caius’s much better looking younger brother. Don’t tell him I said that, he gets prickly.”

“Seraphina Ashcroft.”

“I know who you are.” Something in the way he said it made her look up sharply, and for just a moment the easy charm dimmed, replaced by something more assessing. Then it was gone, tucked away so smoothly she almost doubted she’d seen it. “Caius mentioned a new hire. Didn’t mention you’d be this interesting.”

“I’m not that interesting. I’m a chemist who needed a job.”

“Everyone who ends up in this house needed something,” Lucien said, and there was a weight to it that didn’t match his smile. “That’s rather the point of it, isn’t it.”

“What’s the point of it?”

He laughed, easy and bright, and the shift was so fast Sera wondered if she’d imagined the darker note underneath. “Ignore me, I’m being dramatic. It’s a family trait, apparently, though Caius expresses his differently. Mine’s charm. His is ice.” He plucked a flower from her basket, twirled it, handed it back with a flourish. “Has he shown you the west wing yet?”

Sera’s hand tightened on the basket handle. “No one’s shown me the west wing. It’s rule number two.”

“Ah.” Lucien’s expression did something complicated, amusement and something darker braided together so tightly she couldn’t separate them. “Right. Rule number two. Best rule in the book, that one. Follow it closely, Miss Ashcroft. I mean that as a friend.”

“Are we friends?”

“We could be.” He smiled, and this time it reached his eyes, warm and genuine and disarming in a way that made her instinctively want to trust him, before some quieter instinct reminded her that everyone in this house seemed to be exactly what they wanted her to see and nothing more. “I’m the fun Vale brother. Ask anyone.”

“What does the fun Vale brother do, exactly? For work, I mean.”

“Officially, I sit on two boards and consult for the aviation division whenever Caius needs someone charming enough to close a deal he’s too cold to close himself.” He said it lightly, though something flickered behind the words, quickly smoothed over. “Unofficially, I mostly try to remind my brother that a life can exist outside of quarterly earnings reports. He doesn’t always appreciate the reminder.”

“That sounds lonely. For him.”

“Caius has been lonely since he was seventeen years old, Miss Ashcroft. I don’t think there’s a reminder loud enough to fix that.” Something genuine and sad crossed his face before the charm reasserted itself, smooth as water closing over a stone. “But don’t tell him I said anything that serious. It’ll ruin my reputation.”

“Ask anyone” turned out to mean ask Noemi, who, when Sera brought it up over dinner prep in the kitchen that evening, went uncharacteristically quiet.

“Lucien’s charming,” Noemi said carefully, chopping herbs with more focus than the task required. “Everyone likes Lucien. That’s sort of the problem.”

“What do you mean?”

“I mean Caius has spent his whole life being the responsible one, the cold one, the one who holds the empire together with his bare hands while everyone calls him the Ice King behind his back.” Noemi set down the knife. “And Lucien gets to be charming, and funny, and everyone forgives him everything, because he smiles so easily you forget to ask what he’s smiling about.”

“That sounds like resentment.”

“It sounds like observation.” Noemi’s eyes flicked toward the doorway, checking, Sera realized, whether anyone was listening. “Look, Sera, I like you. You’ve been here a week and you’re already asking the questions everyone else stopped asking years ago. That’s either very brave or very stupid, and I haven’t decided which yet. But do yourself a favor. Watch Lucien’s smile. Watch how it never quite reaches his eyes when Caius’s name comes up. And be careful what you tell him.”

“Why?”

“Because I don’t know what he does with what people tell him,” Noemi said simply. “And in six years, I’ve never once caught him lying. Which, in a house like this, should worry you more than if he had.”

Sera turned that over for the rest of the evening, sitting in the small library with a book she wasn’t reading, watching rain begin to streak the windows, thinking about a brother who never lied and a house full of people who flinched at the mention of a locked door.

She was still turning it over when Caius found her there, later than she expected, his tie already loosened, the first crack of exhaustion she’d seen in his usually flawless composure.

“You’re still awake,” he said, more observation than question.

“I don’t sleep well in new houses.”

“You’ve been here a week.”

“This house doesn’t feel like the kind of place that gets less new with time.” She closed her book, though she’d read perhaps four pages of it. “I met your brother today.”

Something shuttered behind his eyes, fast and complete, a door closing. “Lucien.”

“He said he was the fun Vale brother.”

“Lucien says a great many things.” Caius crossed to the window, looking out at the rain, and for a moment Sera studied his reflection in the glass rather than the man himself, finding it easier somehow to read him sideways than head on. “What else did he say?”

“That I should be careful about the west wing. That it was rule number one, apparently, in his opinion, if not officially.”

Caius’s jaw tightened. “He’s right about that much.”

“Is he right about anything else?”

“I don’t know what you’re asking, Miss Ashcroft.”

“I’m asking if I should trust him,” Sera said plainly, tired of the careful sideways conversations this house seemed to specialize in. “Everyone here talks to me like I’m walking through a minefield blindfolded and no one will hand me the map.”

Caius turned from the window, and for a moment, just a moment, something in his expression looked almost like exhaustion, real and unguarded. “Trust is not something I can hand you a map for, Seraphina.”

It was the first time he’d used her first name. She noticed it the way she noticed a reaction change color, small and significant and impossible to unsee.

“Then what can you give me?” she asked quietly.

He was silent long enough that she thought he wouldn’t answer at all. Then: “A warning. Trust Edmund. Trust Mireille. Trust Orion with your safety, if nothing else. Be careful with Noemi’s kindness, it’s real, but it comes with opinions she won’t always share directly.” He paused at the door, hand on the frame, not quite looking back at her. “And be very, very careful with my brother’s smile. It has cost people more than they expected to pay.”

He left before she could ask what he meant, and Sera sat alone in the library with the rain against the glass, adding one more locked door to the growing list of things in this house that no one would explain, only warn her about.
