Old habits didn't change easily.*

Here's the corrected version of your text:

Eunji left at the first sight of the sun's rays; she wasn't the best example to anyone. She didn't sleep well, eat well, her mood was bad, and her patience nonexistent. Well, would anyone put up with her if she weren't paid for it?!

She had no real hope that someone would choose to put up with her simply out of love; there must be some limit to sadomasochism. After all, limits must exist, right?!

She drove to her company, but there weren't many employees yet, few needed to come on Saturdays if she wasn't working overtime.

Junseo anxiously waited for her along with her list of the day's innumerable tasks.

He felt sleepy and tired, he hadn't even worked a full week and was already exhausted.

He took a deep breath, letting all the air out of his lungs, another day of work and martyrdom.

Each had their own cross to bear.

"Miss."

Eunji just threw the car keys to Junseo and hoped he knew how to drive; she wouldn't bother parking.

Her head felt like it was about to explode.

Young Kim was walking with firm, slow steps towards the elevator.

Junseo could see his boss's tired face, in addition to the repeated clothes.

She clearly hadn't spent the night at home.

"Good morning, buy coffee and take it to my room."

Eunji didn't mind her secretary spending on her card; if he bought what she sent, he could buy something for himself too.

It made no difference to her bank account.

The secretary nodded obediently and was already getting ready to go in search of coffee until he heard Eunji's voice once more. "Did you get the names I asked for?"

"Yes, the list is already on your desk."

Of course he had; it had taken a full night of sleep to get it in time.

Kim smiled. "Fine... Buy me something to eat and some headache medicine."

"R-right."

The young president put her fingerprints on and saw the elevator doors finally opening for her. But what she saw as she walked in and turned to face the door was her secretary standing statically in the same spot as before with a confused expression on his face.

She massaged her temples; drinking without eating was really troublesome.

"Bring sandwiches and don't overthink what I like to eat. Just remember one detail: if it's not sweet, I can eat well."

Junseo always felt insecure about buying food for Eunji... How would he know if it was something she would enjoy eating?!

He nodded in agreement and made a mental note: avoid sweets, except lemon ice cream.

"OK."

Meanwhile, on the other side of town, Hye-jin faced the new disguise prepared by Mark.

She really hated him a lot now.

"Mark, what the hell is this?"

Mark laughed shamelessly; he felt his belly hurt. How can they say that crime doesn't pay when you laugh like that?! Very good.

Hye-jin watched the taxi parked in her garage.

That was a joke, right?

"That's a perfect disguise."

Young Jeon opened the driver's door and came across the car's documents all in her name... Yes, it was indeed the cover of the day.

"Seriously?"

"Absolutely."

"Yesterday, I was an ice cream saleswoman, and today I'm going to be a taxi driver?"

Mark was laughing as he ate his nightly snacks; Hye-jin could hear him chewing fervently. Did that idiot just know how to eat? It felt like he just did this all day.

She rolled her eyes in irritation.

Next to the documents was a uniform, and this time her outfit would be simple with just black pants and a white blouse, no big deal.

Of course, no blonde wigs.

Mark was filling his mouth and looking like he was eating like a savage.

Maybe he was Tarzan's cousin, or something similar.

She quickly put on her clothes while watching the last details of the documents and accessories that made up her look.

"It was the best in such a short time. Also, do you think I don't sleep?"

"I don't pay you to sleep."

She pressed the button for the gate to open and finally got out in her car.

Mark had arranged for her to have a privileged view of the park coordinated by Kim companies.

She would have a direct view of the presidency's room.

Also, Mark had gotten Eunji's personal schedule.

Well, how to say? She had no personal life.

Her appointments were Sunday through Sunday down to meetings, and there wasn't a day for the next month that she didn't leave after 10 pm.

Even she would be in a meeting in half an hour.

She drove quietly as she watched the growing traffic of cars.

Hye-jin could walk around the city without any GPS help.

Killing people made you go through every possible place in the city, every day a different discovery.

"Mark, have you made any headway with the cameras inside the building?"

Mark let out a weary mutter; that company's security system was so good it irritated him.

"No, we will need to make some adjustments manually."

"Seriously? Great..."

She really should have charged more for this service. One problem after another.

Manual adjustment meant: Hye-jin would have to personally break into the security system, risking arrest, death, and the adjacencies.

"Yes, I need you to put a virus in their files so we can access them; without that, the most I can do is see the city's security system cameras in real-time."

Hye-jin preferred not to think about how troublesome that would be; thinking about facing traffic seemed like the least stressful option, even though the traffic was completely stopped. "You already know what to do."

Mark smiled; it sounded like music to his ears. "Of course, a new disguise. Next week the team that takes care of the ventilation system will have to pay a visit for repairs, and they will be very close to the surveillance room, and I already got your employee badge."

"Great, but keep an eye on the street cameras; there's not much to do."

"Right."

Mark already had the cameras open on his computer; he was your typical movie hacker geek: sitting all day in front of his computer staring at its wall full of monitors.

Mark was a college art student before he started working with Hye-jin, but now a lot of his day was spent on a life of crime, sleeping, and painting.

He often stayed on the phone with Hye-jin without any action or use, so to pass the time, he painted.

Old habits didn't change easily.

At that moment, he was staring at his red-colored inks; he had his favorite brands for different purposes. Choosing the first color was always a big dilemma.

"How was your uncles yesterday?"

Hye-jin finally got out of the huge traffic jam. She smiled satisfied. "Relax, they are managing to pay the building financing."

Young Jeon had no problem talking about the details of her life; it wasn't like Mark wouldn't find out if he tried, so why hide it?!

Here's the corrected version of your text:

Mark didn't understand how Hyejin could be so good at hiding her secret life; she was probably the biggest assassin for hire in the country, and they lined up to have her services, so money wasn't an issue. "Why don't you pay them all the money soon?"

"That would attract a lot of attention."

"Having a laundry and a cafeteria doesn't call for suspicion?"

Hyejin didn't mind having a cafeteria and a laundry room; as clichéd as it was, it was useful and easy to manage.

Her laundry room was in an upscale area, and the rent was so expensive that it sometimes gave her a big headache. But she could make a good income just from the good location; she could charge an exorbitant amount just for washing rich people's clothes.

"It's the best way to launder money, don't be annoying."

Mark stopped staring at the shades of red when he noticed a small movement in one of the cameras. Eunji had finally arrived.

"Target just arrived... She drove this time."

Hyejin was five minutes away from the Kims' building; she wouldn't make it in time to see Eunji enter the building.

"Anyone around?"

"Just the handsome secretary."

Young Jeon laughed; Mark really wasn't worth a penny.

"By the time you got there, she has a shareholders' meeting today."

"Yes, in exactly 13 minutes, the meeting should start."

"Good."
