Mina didn't mean to tell anyone.
It slipped out the way most personal details slipped out of her life, by accident, in the middle of something boring.
Cora was squinting at Mina's staff profile for a verification check when she frowned.
"Hold on," Cora said. "Your status updated."
Mina leaned in. "Updated how?"
Cora scrolled. "Age flag lifted. You're cleared for extended rotations."
Mina nodded. "Right. That makes sense."
Cora went still. "You turned eighteen."
Mina shrugged. "Yeah. Last week."
Cora stared at her like Mina had just confessed to eating glass.
"Last week," Cora repeated. "And you said nothing."
Mina hesitated. "I didn't think—"
"That's not a sentence," Cora cut in. "That's a crime."
Lira, who had been pretending not to listen while absolutely listening, turned slowly in her chair.
"Okay," Lira said. "So we're doing something."
Mina's stomach dropped. "No, you don't have to—"
"We do," Lira said firmly. "Not because of the birthday. Because of the part where you thought you weren't allowed to have one."
Mina blinked. "I didn't—"
Lira pointed at her. "You did."
Then she stood and looked around the library staff area like a general preparing for war.
"Tomas," Lira called. "Don't ask questions. Help."
Tomas glanced up from across the room. "That sentence always ends badly."
"It ends with cake," Lira said. "Move."
⸻
It wasn't elaborate.
That was what made it hit harder.
No banners. No big announcements. No fake cheer. Just a quiet shifting of people staying a little later than usual, like the building had decided to hold its breath for ten extra minutes.
Someone brought a cake from the lower kitchens. Someone else found candles that definitely weren't meant for a cake. Cora stole paper plates from a supply cart like it was a high-stakes mission.
Mina sat at the end of the table, hands in her lap, feeling awkward in the way she always did when attention landed on her.
"This is unnecessary," she said, voice small.
Cora snorted. "It's sugar. It's always necessary."
Tomas put a small box in front of her.
Mina stared at it like it might bite.
"It's nothing," Tomas said quickly. "Just open it whenever."
Mina opened it immediately because the tension of not opening it was worse.
Inside was a notebook. Plain cover. Thick pages.
"For writing things down," Tomas said, a little too casual. "You keep using scraps. Half the time your scraps end up in my pocket somehow."
Mina's throat tightened. "Thank you."
Lira leaned in, elbows on the table. "Okay. We're not singing. That's cruel. But you have to blow out the candles."
"And make a wish," Cora added.
Mina stared at the cake.
The candles flickered unevenly. Wax already dripping.
"I don't really—" Mina started.
"Yes, you do," Lira said softly. "You just don't think you're allowed."
That stopped Mina cold.
She took a breath, leaned forward, and blew.
All the flames went out at once.
People clapped, laughed, started talking again like they hadn't just done something huge.
Mina sat there with a paper plate in her hands, listening to the noise fill the room.
It wasn't loud joy.
It was normal joy.
And Mina realized, suddenly and painfully, that she didn't know what to do with it.
⸻
It happened when she stood to help clear plates.
Cora immediately snapped, "Sit down. You're the birthday person."
"I don't know what that means," Mina said honestly, reaching for a stack of plates anyway.
"That means," Lira said, "you're allowed to be taken care of for five minutes."
Mina flushed and looked down, embarrassed, and that was when a hand landed on her waist.
Not hard.
Not violent.
Just… familiar.
Too familiar.
Mina froze.
The guy wasn't Tomas. Wasn't anyone she knew well. One of the newer staff, always lingering, always joking too much, the kind of man who tested boundaries like it was a hobby.
"Relax," he said, smiling like she was being dramatic. "I'm helping."
Mina's stomach turned.
Her first instinct was to laugh it off. Step away. Make it small.
But something in her snapped into place, not confidence, exactly.
Clarity.
Mina gently but firmly removed his hand from her waist, like she was lifting it off a hot surface.
"Don't," she said.
He blinked, still smiling. "Don't what?"
"Don't touch me," Mina said, calm and even. Not loud. Not shaky. "If you want to help, pick up plates. Not me."
The room didn't go silent, not fully, but it shifted.
Cora straightened so fast her chair scraped.
Lira's expression went flat in a way Mina had never seen before.
The guy's smile twitched. "Okay, wow. I was just—"
"I know what you were doing," Mina said quietly. "You can stop."
He stared at her for a second, then did what men like that always did when they realized they'd pushed too far.
He laughed, small, fake, dismissive.
"Whatever," he muttered, and walked away like he hadn't done anything.
Mina stood there with a stack of plates in her hands, heart beating hard, face warm.
Cora came to her side immediately. "You okay?"
Mina nodded, but her throat felt tight. "Yeah. I'm fine."
Lira took the plates from her without asking. "Go sit."
Mina obeyed because she suddenly didn't trust her own legs.
⸻
The next day, the story was already everywhere.
Not the real version.
The staff version.
"She shut him down cold."
"She didn't even raise her voice."
"She didn't smile."
"He looked like someone slapped him."
People said it like it was entertainment. Like it was proof of something.
Mina kept her eyes on her work and tried to pretend she didn't hear any of it.
But she did.
⸻
Sentinel registered it later.
Not with drama. Not with confrontation.
A short incident note hit his queue: unwanted physical contact, boundary asserted, no escalation, no further risk observed.
He read it once.
Then again.
Then he opened the staff profile attached, the man's name, the pattern of minor flags, the small history that people dismissed until it became a habit.
Sentinel made a single adjustment.
Nothing loud. Nothing visible to staff.
Just a quiet restriction. A shift in assignments. A schedule that would keep that man away from Mina's work areas without anyone having to explain why.
He closed the file.
And somewhere in the estate, a corridor became safer.
Not because Mina asked for protection.
Because someone noticed she shouldn't have to.
