The bustling police department was filled with officers working tirelessly, the air thick with tension and anticipation.
The lead officer, Captain Lee, paced back and forth in his office, barking orders into his phone.

Captain Lee: (hanging up the phone) "We've got a lead on Yoongi. None of us know exactly what he looks like, but this is our best chance to catch him. Move out!"

A team of officers, heavily armed, gears up and heads out. The scene cuts to a dark alley where the officers converge, only to find the lead was a dead end. Frustration mounts as Yoongi remains elusive.

Back at the police department, Namjoon and Jimin, the officers in charge of Yoongi's case, are in deep discussion.

Namjoon: "Another false lead. This guy is a ghost."

Jimin: "Yeah, but we can't give up. The head officer wants us to consult with our best hacker, Vespera."

Namjoon: (raising an eyebrow) "Vespera?"

Jimin: (smirking) "Oh, it's YN, hyung. She just updated her name to Vespera in the department files. She likes to keep things mysterious."

Namjoon: (chuckling) "Of course, she did. She's been a mystery for as long as I've known her. Ten years, and she's still an enigma. Her job suits her perfectly."

Jimin: "Exactly. She's the best in hacking. If anyone can help us crack this case, it's her."

Later that evening, Namjoon and Jimin arrive at YN's house. The cozy, cluttered space is filled with computer equipment and paintings, reflecting her dual passions.

YN: (opening the door) "Hey, guys! What's up?"

Namjoon: "Hey, Vespera. We need your help with a case."

YN:" Stop teasing now...tell me what gets you here..cause as I know you both don't have time for me "

Jimin: "Yeah, it's about Yoongi. The head officer wants us to get you on this."

YN:(nodding) "Come on in. Tell me everything."

They settle in the living room, the atmosphere shifting from professional to friendly as they catch up.

YN: "So, Yoongi, huh? The ghost of the underworld. I'll see what I can do. I'll start tonight."

Namjoon: "We know you will. You're the best, YN."

Jimin:"Yeah, just be careful. This guy is dangerous."

After Namjoon and Jimin leave, YN gets to work. She starts by gathering all available information on Yoongi. Her fingers fly across the keyboard as she digs deeper into the digital underworld.

YN: (muttering to herself) "Yoongi, Yoongi... Let's see what secrets you're hiding."

She discovers Yoongi's extensive criminal network and realizes how elusive he is. Determined, she attempts to access his secure documents but is repeatedly blocked.

YN: (frustrated) "Come on... No one blocks me."

She tries again and again, each attempt met with failure. Her frustration grows, fueling her determination.

Meanwhile, in Yoongi's mansion, a subordinate rushes into his office.

Someone:"Boss, we have a problem. Someone's trying to hack into our accounts. They're persistent and skilled."

Yoongi: (leaning back in his chair, intrigued) "Interesting. Keep monitoring it. Let's see who's bold enough to challenge me."
