Under the Surface

The morning sun streamed through the windows of Shinwa Marketing Group as Yuna and Joon reconvened in her office. The air was thick with unspoken thoughts and unvoiced suspicions. Today, they planned to dive deeper into the employees' personal interactions, hoping to unearth any hidden connections or motives.

"Morning, Joon," Yuna greeted him with a determined nod.

"Morning, Yuna. Ready for another day of playing detective?" Joon replied with a slight smile.

"Always," Yuna said, returning his smile. "Let's start with Min-seok. His cheerful demeanor makes it hard to suspect him, but we can't overlook anyone."

"Agreed," Joon said, setting down his coffee. "Let's see what we can find."

They headed to Min-seok's office, where he was already immersed in his work. Min-seok looked up and greeted them warmly.

"Good morning, Yuna, Joon. What brings you to my corner of the world?" Min-seok asked, flashing his usual bright smile.

"Good morning, Min-seok. We just wanted to ask you a few questions about the recent leak," Yuna said, trying to sound casual.

"Of course. Anything I can do to help," Min-seok replied, his expression earnest.

"Have you noticed anything unusual or anyone acting out of character?" Joon asked, leaning against the doorframe.

Min-seok thought for a moment, then shook his head. "I can't say I have. Everyone seems to be their usual selves. But I'll keep my eyes open."

"Thanks, Min-seok. We appreciate it," Yuna said.

As they walked away, Joon turned to Yuna. "He seems genuine, but we should still keep an eye on him."

"Agreed," Yuna said. "Let's check in with Seo-jin next."

They found Seo-jin in the break room, chatting with a few colleagues. When she saw Yuna and Joon, she excused herself and walked over to them.

"Hi, Yuna, Joon. Any updates?" Seo-jin asked, her tone friendly.

"Not yet. We wanted to ask if you've noticed any unusual behavior or anything that seemed off lately," Yuna said.

Seo-jin shook her head. "I've been keeping an eye out, but nothing has stood out to me. Everyone seems normal."

"Thanks, Seo-jin. If you do notice anything, let us know," Joon said.

"Will do," Seo-jin replied with a smile.

As they left the break room, Yuna couldn't shake the feeling that they were missing something. Everyone seemed so cooperative and friendly, but she knew appearances could be deceiving.

"Let's dig into the company's communication logs," Joon suggested. "There might be something there that we've overlooked."

"Good idea," Yuna said. "Let's head to the IT department."

They spent the next few hours going through the communication logs with the help of the IT team. They looked for any unusual patterns or messages that might point to the source of the leak. It was tedious work, but they were determined to find a lead.

Just as they were about to call it a day, Yuna's phone buzzed with a message from Ji-won.

Ji-won: Yuna, do you have time to chat tonight? I need some advice.

Yuna: Sure, Ji-won. I'll call you when I get home.

Yuna turned to Joon. "Ji-won needs some advice. I'm going to head home and call her."

"Alright. Get some rest, Yuna. We'll continue this tomorrow," Joon said.

"Thanks, Joon. See you tomorrow," Yuna replied.

Later that evening, Yuna settled onto her couch and called Ji-won. The phone rang a few times before Ji-won picked up.

"Hey, Yuna!" Ji-won said, her voice cheerful but with an undercurrent of worry.

"Hey, Ji-won. What's up?" Yuna asked.

"I need your advice about Min-woo," Ji-won said, sounding a bit anxious. "Things have been going really well between us, but he's been acting distant the past few days. I'm not sure what to do."

Yuna frowned, thinking about her friend's situation. "Have you talked to him about it?"

"I tried, but he just says he's been busy with work," Ji-won replied. "I don't want to pressure him, but I'm worried something else might be going on."

"Maybe he's just stressed about something," Yuna suggested. "Give him some space, but let him know you're there for him."

"You're right. Thanks, Yuna," Ji-won said, sounding relieved. "How's the investigation going?"

"It's slow," Yuna admitted. "Everyone seems so friendly and cooperative, but we haven't found any solid leads yet."

"Hang in there. You'll figure it out," Ji-won said encouragingly. "And remember to take care of yourself too."

"I will. Thanks, Ji-won," Yuna said, feeling a bit better. "Talk to you soon."

As Yuna hung up, she couldn't help but think about Ji-won and Min-woo. Relationships were complicated, whether they were personal or professional. She hoped things would work out for her friend.

The next morning, Yuna and Joon resumed their investigation with renewed determination. They decided to focus on the department heads, as they had the most access to sensitive information.

"Let's start with Soo-bin again," Joon suggested. "We need to dig deeper into his activities."

They approached Soo-bin's office, finding him engrossed in his work as usual.

"Soo-bin, do you have a moment?" Yuna asked, knocking on his door.

"Of course, come in," Soo-bin replied, looking up from his computer.

"We wanted to ask you about the financial reports," Yuna began. "Have you noticed any discrepancies or unusual transactions?"

Soo-bin shook his head. "No, everything seems to be in order. But I'll double-check and let you know if I find anything."

"Thank you, Soo-bin," Joon said. "We appreciate your cooperation."

As they left Soo-bin's office, Yuna sighed. "This is getting us nowhere. Everyone seems so genuine."

"We need to approach this from a different angle," Joon said thoughtfully. "What about the personal lives of the employees? Maybe there's something there that could give us a clue."

"That's a good idea," Yuna agreed. "Let's start with Min-seok. He's always so cheerful, but maybe there's something beneath the surface."

They decided to visit Min-seok after work, hoping to catch him in a more relaxed setting. They found him at a nearby bar, enjoying a drink with some colleagues.

"Hey, Min-seok," Yuna greeted him, taking a seat beside him.

"Yuna, Joon! What a surprise," Min-seok said, smiling. "What brings you here?"

"We just wanted to catch up," Yuna said casually. "How have you been?"

"Good, good," Min-seok replied. "Just the usual work stuff. How about you two?"

"We're managing," Joon said with a chuckle. "It's been a busy week."

As they chatted, Yuna kept a close eye on Min-seok's demeanor. He seemed relaxed and genuine, but she knew better than to take things at face value.

After a while, Min-seok excused himself to get another drink. Yuna turned to Joon, her expression serious.

"What do you think?" Yuna asked quietly.

"He's hard to read," Joon admitted. "But we can't rule him out."

Min-seok returned with his drink, and they continued their conversation. Yuna decided to probe a bit deeper.

"Min-seok, have you ever noticed anything strange at the office?" Yuna asked, trying to sound casual.

"Strange? Like what?" Min-seok replied, looking curious.

"Just anything out of the ordinary," Yuna said. "We've been dealing with some issues lately, and we're trying to figure things out."

Min-seok frowned, thinking. "I can't say I have. But if I do, I'll let you know."

"Thanks, Min-seok," Yuna said, smiling. "We appreciate it."

As they left the bar, Yuna felt frustrated. They were no closer to finding the mole, and time was running out.

"We'll figure this out," Joon said, sensing her frustration. "We just need to keep digging."

"You're right," Yuna said, taking a deep breath. "Let's keep going."

The next few days were a blur of interviews and data analysis. Yuna and Joon left no stone unturned, determined to find the source of the leaks. They interviewed more employees, dug deeper into the communication logs, and scrutinized financial records.

One evening, Yuna received a message from Ji-won.

Ji-won: Yuna, I need to talk to you. Can we meet tomorrow?

Yuna: Of course. What's wrong?

Ji-won: It's about Min-woo. I think he's hiding something.

Yuna's heart sank. She hated seeing her friend in distress, but she knew she had to be there for her.

Yuna: I'll be there. Hang in there, Ji-won.

The next day, Yuna met Ji-won at a quiet café. Ji-won looked anxious, her usual bright demeanor subdued.

"Yuna, I'm so glad you're here," Ji-won said, hugging her tightly.

"What's going on, Ji-won?" Yuna asked, concerned.

"It's Min-woo. He's been acting so strange lately," Ji-won said, her
