My Ruthless Ceo

Chapter 1: The Chair He Wasn't Supposed to Sit On

The Sinclair Tower was the kind of building that made you feel small on purpose.

Glass that reflected the sky. Marble floors that echoed every step. Security guards who looked at your resume like it was a criminal record.

Noah Reed hated it already, and he hadn’t even made it past the lobby.

“Interview Room 7B. 9:00 AM sharp,” the receptionist had said, without looking up. “Don’t be late. Mr. Sinclair doesn’t tolerate lateness.”

Noah had been unemployed for three months. Three months of instant noodles, rejected applications, and his mom’s worried phone calls. This was his last chance. The last company that hadn’t auto-rejected him.

He clutched the folder with his resume like it was armor. Wrinkled shirt, borrowed tie, shoes polished twice that morning. He’d practiced answers in the mirror. I’m a hard worker. I learn fast. I’m very detail-oriented.

The elevator shot up 70 floors in 20 seconds. His ears popped. His hands sweated.

Wrong turn. Wrong hallway. Wrong door.

It should’ve been 7B. Instead, the gold plaque said: KAIRO SINCLAIR – CHIEF EXECUTIVE OFFICER. NO ENTRY WITHOUT APPOINTMENT.

Noah froze. His brain short-circuited. The door was half-open. He could hear the quiet hum of the AC, the distant sound of the city below. And he could see it — the chair.

Massive. Black leather. Tall back, like a throne. Sitting in front of floor-to-ceiling windows that showed all of Chicago sprawled underneath.

His knees gave out. Not dramatically. Just… tired. He’d been up since 4 AM rehearsing. He hadn’t eaten. He just needed to sit for one second.

He didn’t mean to. He really didn’t. But his legs buckled and the leather caught him. It was still warm, like someone had just stood up. The scent hit him next — cedar, expensive cologne, and power.

Noah’s eyes widened. “Oh no. Oh no—”

The door slammed open behind him.

The air in the room dropped ten degrees.

“Get. Out. Of. My. Chair.”

The voice wasn’t loud. It didn’t need to be. It cut through the room like a blade.

Noah turned slowly, like he was in a horror movie.

Standing in the doorway was a man who looked carved from ice and tailored wool. Pinstripe suit, no tie. Dark hair, perfectly messy. Eyes so dark they looked black. He held a slim folder in one hand, but the way he held it made it look like a weapon.

Kairo Sinclair.

The name was everywhere. Youngest CEO in Sinclair Corp history. Ruthless. Brilliant. The man who’d fired his own uncle during a board meeting. The man who didn’t do second chances.

Noah scrambled up, face burning. His resume slipped from his folder and scattered across the floor like confetti at a funeral.

“I’m so sorry, Mr. Sinclair, I swear I was looking for 7B, the interview room, I took the wrong turn, I didn’t mean to—”

Kairo didn’t blink. He walked in, closed the door behind him with a soft click that felt louder than the slam. He set the folder down on the desk. Then he looked at the chair. Then at Noah.

“You’re early,” he said. Flat. No emotion. “You’re unqualified. And you’re sitting in my chair.”

Noah bent to pick up his resume, hands shaking. “I can explain, I just—”

“30 seconds.” Kairo leaned against the desk, arms crossed. “Explain why I shouldn’t have security escort you out right now.”

30 seconds. For the rest of his life.

Noah’s mind went blank. All those practiced answers evaporated. He looked up through his glasses, and for some reason, honesty was the only thing left.

“I don’t know,” he whispered. “I don’t have a good reason. I’m tired. I’m scared. I need this job. And when I saw the chair… I just needed one second where I wasn’t failing.”

The words hung there. Too honest. Too much.

Kairo’s expression didn’t change. But his eyes did something subtle. They assessed. Like he was running Noah through a calculator in his head.

“You’re trembling,” Kairo observed.

“It’s cold in here.”

“It’s 22°C.”

Noah swallowed. “Then it’s me.”

Another pause. The city kept moving 70 floors below. Kairo picked up his folder, opened it, then closed it again.

“You have no experience,” he said. “Your GPA is average. You quit your last job after 6 months. On paper, you’re exactly the kind of person I fire on sight.”

Noah’s heart sank.

“But,” Kairo continued, “you didn’t make excuses. You didn’t lie. You sat in my chair knowing I’d destroy you for it. That’s either stupidity… or guts.”

Noah didn’t know which one he was. Maybe both.

Kairo walked around the desk and stopped in front of him. Close. Noah could smell the cedar cologne now. He could see the faint scar on Kairo’s jaw. He could see that Kairo’s eyes weren’t black. They were dark brown. Almost human.

“5 minutes,” Kairo said finally. He gestured to the chair. “In that chair. Convince me.”

Noah stared. “Sir?”

“You heard me. Sit down. 5 minutes. Tell me why I should let you stay in this room instead of calling security.”

Noah’s legs shook as he sat back down. The leather felt even warmer the second time. Like it remembered him.

He had 5 minutes. No resume. No rehearsed speech. Just him.

“I’m good at remembering things,” he started, voice small. “I notice patterns. I notice that your assistant before me lasted 2 weeks because she kept scheduling your meetings during your coffee break. I notice that you prefer your blinds at 70% closed, not fully open. I notice that when you’re thinking, you tap your pen twice, then stop.”

Kairo’s pen was in his hand. He stopped tapping.

“I don’t know much,” Noah continued, gaining a little courage. “But I know how to pay attention. And I know how to make sure the person I work for doesn’t have to worry about the small things. So they can focus on the big things. Like running a company. Or firing people.”

Silence.

Kairo walked back to his side of the desk. Sat down. Didn’t look at Noah for a long time. Just typed something on his computer.

Finally, he spoke without looking up. “Your interview was in 7B. At 9:00 AM. It’s 8:57.”

Noah’s stomach dropped.

“You’re late for your interview,” Kairo said. Then he looked up. “But you’re early for mine.”

Noah blinked. “What?”

“Secretary position. My secretary quit yesterday. Threw her resignation on my desk and walked out. Said working for me was ‘soul-crushing.’” Kairo leaned back. “I need someone who won’t flinch. Someone who notices things. Someone who isn’t afraid to sit in my chair when they have to.”

He slid a contract across the desk. One page. Simple.

Noah stared at it. “You’re hiring me? Just like that?”

“I’m not hiring you,” Kairo corrected. “I’m testing you. 3-month probation. You mess up my coffee once, you’re gone. You mess up my schedule twice, you’re gone. You sit in that chair again without permission, you’re gone.”

Noah picked up the pen. His hand shook as he signed. Noah Reed.

When he looked up, Kairo was watching him. Not cold. Not warm. Just… watching.

“One more thing,” Kairo said as Noah stood. “That chair? It’s ergonomic. Custom made. Don’t get used to it.”

Noah nodded, clutching the contract. “Yes, sir.”

He was at the door when Kairo’s voice stopped him.

“Noah.”

He turned.

Kairo didn’t smile. Kairo Sinclair didn’t do that. But his voice was quieter when he said: “Don’t be late tomorrow.”

Noah walked out of the office in a daze. He’d come for an entry-level interview. He’d left as the personal secretary to the most feared CEO in the city.

He had no idea he’d just been hired… as Kairo’s personal exception.

And he had even less idea that the man who just hired him would never let him sit in that chair again… unless he was the one who told him to.

Chapter 2: First Day, Worst Coffee

Noah showed up 45 minutes early. That was mistake number one.

Mistake number two was thinking “early” would earn him points with Kairo Sinclair.

The Sinclair Tower at 7:15 AM felt like a different building. No crowds. No echoing footsteps. Just silence, glass, and security guards who now recognized his face. They scanned his new ID badge without a word. NOAH REED – SECRETARY TO CEO. The title still didn’t feel real.

The elevator ride to the 70th floor gave him time to rehearse. Good morning, Mr. Sinclair. Your schedule is ready. Your coffee will be 82°C. One ice cube. He’d written it on his palm like a cheat sheet.

The CEO’s office was already lit. Floor-to-ceiling windows, the city still dark and glittering below, and Kairo standing with his back to the door. White shirt, sleeves rolled to the elbows, no tie. He looked less like a CEO and more like a man who hadn’t slept. Hair slightly messy. Shoulders tense.

He didn’t turn when Noah entered.

“Mr. Sinclair?” Noah’s voice came out quieter than he intended. “I’m here. For work.”

“Secretary,” Kairo corrected. Still facing the window. “Not assistant. Not intern. Not ‘the kid who panicked in my chair yesterday.’ Secretary. My schedule, my files, my coffee. In that order.”

He turned then. Dark eyes, sharp and assessing. Like he was scanning Noah for weakness and finding plenty.

“You’re 45 minutes early,” Kairo said. He walked to his desk and slid a sticky note across the surface. Perfect black handwriting. Black coffee. No sugar. One ice cube. 82°C. Delivered at 8:00 AM sharp. Not 7:59. Not 8:01.

Noah stared at the note. “82 degrees?”

“Any hotter and the beans burn,” Kairo said. “Any colder and it’s water pretending to be coffee. I don’t waste time on pretense, Noah.”

He said Noah’s name like he was still deciding if it was worth remembering.

“You have 10 minutes,” Kairo continued, already looking back at his tablet. “Kitchen is third door on the left. Don’t destroy the equipment. The last secretary did. She also cried. I don’t have time for tears.”

Noah nodded and bolted.

The office kitchen was terrifying. Stainless steel, spotless, and three coffee machines that looked like they belonged in a lab. None were labeled. One had a warning taped to it: DO NOT TOUCH. K.S.

His hands shook. He burned his tongue testing the water. Spilled grounds across the counter. Set off the smoke alarm once when the steam function went wrong. By 7:58 AM he was sprinting back down the hall, mug clutched in both hands, one ice cube floating perfectly on top. He’d used a thermometer app on his phone. 81.8°C. Close enough.

He pushed the door open with his shoulder at exactly 8:00 AM.

Kairo looked up at the second the second hand hit twelve. He picked up the mug, brought it to his lips, sipped.

One second. Two seconds. Three.

Noah forgot how to breathe.

Kairo set the mug down. Didn’t drink again.

“79 degrees,” he said flatly.

Noah’s stomach dropped. “I swear I checked— my phone said 81.8—”

“Your phone is wrong. Or you’re slow.” Kairo opened his laptop. “Try again. 5 minutes.”

Five minutes. Noah ran. Back to the kitchen. Back to the machines. His phone thermometer crashed. He guessed. He prayed. He poured, holding his breath.

This time he walked back in with a coffee stain blooming on his sleeve. He didn’t notice. Didn’t care.

Kairo took the mug. Sipped. Paused.

Noah braced for the word “fired.”

Kairo drank half the mug before setting it down. For ten seconds he said nothing. Just typed on his keyboard, the sound sharp in the quiet.

“82°C,” he said finally. “Exact.”

Noah exhaled so hard his knees felt weak. “Thank you, sir.”

“Don’t thank me yet.” Kairo turned the massive screen behind his desk on. A calendar exploded across it, color-coded down to 5-minute blocks. “30 seconds. Memorize today. Then I’ll delete it.”

Noah’s eyes darted. 9:00 AM — Board check-in. 9:30 AM — Investor call, Tokyo. 10:15 AM — Budget review, Q3. 11:00 AM — Coffee. 11:05 AM — Termination meeting.

“Termination?” Noah blurted.

Kairo glanced at him. “Performance review. The man will be fired. I don’t schedule reviews unless the outcome is decided.” He closed the calendar. Screen went black. “Recite it.”

Noah closed his eyes. Board. Tokyo. Budget. Coffee. Fire. He missed the time on the budget review but got the order right.

Kairo nodded once. Minimal. “Not terrible. For someone unqualified.”

Noah let himself relax a fraction. Maybe he wouldn’t be fired in the first hour.

Then Kairo added, still typing: “You didn’t flinch yesterday. When I said I destroy people who waste my time. Most do.”

Noah looked up, surprised. “I’ve been yelled at by worse.”

Kairo’s fingers paused on the keyboard. “Worse than me?”

“My mom,” Noah said before his brain could filter it. Then immediately wanted to disappear. “I mean— she’s terrifying when I forget to call on Sundays.”

For half a second, Kairo’s mouth did something that wasn’t quite a smile. It was smaller. Quieter. Like his face forgot how to be ruthless for a moment.

“Don’t be late tomorrow,” Kairo said, turning back to his screen. Dismissal.

Noah backed toward the door, folder clutched to his chest. “Yes, sir. 7:15 AM. 82°C. One ice cube.”

He was halfway out when Kairo’s voice stopped him.

“Noah.”

Noah froze. “Sir?”

“Good coffee.”

The door clicked shut behind him before he could respond.

Noah leaned against the wall in the empty hallway and stared at his shaking hands. Not from fear. From relief. He still had a job. The most feared CEO in the building just said two words that felt like approval.

He didn’t know yet that “good coffee” from Kairo Sinclair was rarer than a raise.

He didn’t know yet that getting the temperature right would become the smallest, most dangerous thing between them.

He just knew he’d be back tomorrow. 45 minutes early. With a real thermometer and a tie that didn’t have coffee on it.

And maybe, if he was lucky, Kairo would remember his name again.

Chapter 3: Overtime at Midnight

Noah lost track of time. Again.

The Sinclair Tower at 11:47 PM was a different kind of quiet. Not peaceful. Heavy. Like the building itself was holding its breath. Only his desk lamp and Kairo’s office light were still on. Floor 70 felt like its own planet.

“Reed.”

Noah jumped. Kairo’s voice came through the intercom on his desk, low and clipped. No greeting. No please.

“Come in.”

Noah grabbed the folder of budget revisions he’d been color-coding for the last 4 hours. His eyes burned. He’d told his mom he’d be home by 8. She’d sent 3 “you okay??” texts. He sent back a thumbs up and prayed she wouldn’t call.

He pushed the door open. Kairo didn’t look up. He was standing by the window again, tie loosened, jacket off, sleeves rolled up. The city lights reflected in the glass behind him. He looked less like a CEO and more like a man who lived at his desk.

“Numbers on Q3 projections are wrong,” Kairo said. He turned half an inch. Just enough for Noah to see the line of his jaw, tense. “Fix them. Now.”

Noah set the folder down. “I already fixed them, sir. Version 4 is on your drive.”

Kairo finally looked at him. Really looked. Eyes tired but sharp, scanning Noah’s face like he was searching for mistakes. Finding dark circles instead.

“You’ve been here 16 hours,” Kairo said. Not a question.

Noah shrugged. Tried to act casual. Failed. “You said the board needs it by 7 AM. I wanted to double-check.”

“You don’t have to double-check my work, Noah. That’s my job.” Kairo walked to his desk and picked up Noah’s mug from earlier. Empty now. Cold. “And you don’t have to stay this late.”

Noah didn’t know what to say to that. “I know, sir. But... you looked stressed earlier. During the investor call. And I thought maybe if I got ahead—”

“Don’t.” Kairo cut him off, but his voice wasn’t cold. Just tired. “Don’t try to fix me, Reed. I don’t need fixing.”

The room went quiet. Only the hum of the AC and the city 70 floors below.

Noah nodded and started backing toward the door. “I’ll send you Version 5 in 20 minutes. Then I’ll go home, I promise.”

“Don’t promise things you can’t keep,” Kairo said suddenly. He walked past Noah to the small kitchenette in his office. Poured water. Didn’t offer any. “You’re still here.”

Noah froze with his hand on the doorknob. “Sorry, sir. The formulas kept breaking—”

Kairo set the glass down harder than necessary. Water sloshed. “Sit.”

Noah sat. In the same chair from Day 1. The “CEO chair” he wasn’t supposed to touch. His back went rigid.

Kairo leaned against his desk, arms crossed. Close enough that Noah could smell his cologne. Expensive. Clean. Tired.

“You’re bad at leaving,” Kairo said. “That’s a problem in this job. Secretaries who care too much burn out in 2 months.”

Noah stared at his shoes. “I don’t burn out easy, sir.”

“No? You look exhausted.” Kairo’s eyes dropped to Noah’s hands. They were shaking a little from too much coffee, too little food. “When did you last eat?”

Noah opened his mouth. Closed it. “Lunch? Maybe?”

Kairo sighed. It was quiet, but Noah heard it. Like the sound of a man giving up on being ruthless for 30 seconds.

He walked to his private mini-fridge, pulled out a wrapped sandwich and a bottle of water, and set them on the desk in front of Noah. Didn’t say anything. Didn’t meet his eyes.

“Eat,” Kairo ordered. “Then go home.”

Noah stared at the sandwich. Turkey. No mayo. The exact kind he bought for himself because it was cheap. He never told Kairo that. He never told anyone.

“How did you—”

“I pay attention,” Kairo interrupted. He was back at the window now, back to Noah again. “It’s my job. I notice when my secretary doesn’t leave his desk for 6 hours and his hands shake.”

Noah unwrapped the sandwich slowly. His throat felt tight. “You didn’t have to do this, sir.”

“I didn’t,” Kairo agreed. “I wanted to.”

Noah nearly choked on his water. Kairo Sinclair saying “I wanted to” felt more dangerous than “you’re fired.”

He ate in silence. Kairo didn’t turn around. Didn’t talk. Just stood there, a shadow against the city lights, while Noah tried not to cry over a turkey sandwich.

When he finished, Noah stood up, folder clutched to his chest. “Version 5 will be in your drive by 12:30 AM, sir. Thank you... for the food.”

Kairo nodded once. Still didn’t turn. “Go home, Noah. That’s an order.”

Noah walked to the door. Paused. “Sir?”

“What.”

“Are you gonna go home too?”

Silence. Then: “No.”

Noah’s chest hurt. He wanted to say you should rest. Wanted to say you don’t have to do this alone. But he was just the secretary. So he just whispered, “Goodnight, Mr. Sinclair,” and left.

The door clicked shut. 

Kairo didn’t move for a full minute. Then he glanced at the empty sandwich wrapper on his desk. Picked it up. Threw it away.

His reflection in the window looked softer than it had all day. 

He muttered to himself, barely audible: “He noticed I was stressed.”

Down the hall, Noah leaned against the elevator wall and pressed the back of his hand to his mouth. He wasn’t sure if he was crying from exhaustion or from the fact that the most feared CEO in the building just bought him dinner.

He didn’t know yet that “overtime” would stop being about work soon. 

He just knew he’d be back tomorrow. And maybe, if he was lucky, Kairo would have another sandwich waiting.
