Y/N sighed as she approached the door and knocked, the anticipation building rapidly. After a moment, the door creaked open, revealing Taehyung standing there, his chest bare and a look of surprise on his face.

"Yeah- What do you- Y/N?" Taehyung exclaimed in shock as he recognized it was Y/N standing in front of him, his eyebrows furrowing slightly at the unexpected encounter.

Y/N's breath caught in her throat as she took in the sight of his toned physique, his muscles glistening under the soft lighting of his room. Her mind went blank for a moment, unable to process the overwhelming attraction she felt in that instant.A flush of heat crept up her neck as she struggled to form coherent words.

"Um- yeah, it's me. Now, move out of the way," she said, mustering up some determination and pushing Taehyung slightly to the side as she made her way inside. However, her boldness was short-lived as her gaze fell upon another guy lying on one of the beds, his eyes widening in surprise as he quickly covered his chest with a nearby sheet.

"Oh, God," Y/N breathed, her exhaustion palpable as she found herself once again in the presence of half-naked men. The awkwardness of the situation lingered in the air, leaving her feeling flustered and overwhelmed by the unexpected sight before her.

"Just- put s-some clothes on, you two," she stammered, her cheeks burning as she averted her gaze from the half-dressed men in the room.

"What are you doing here?" Jimin asked, hastily pulling on his shirt as he tried to make sense of Y/N's unexpected visit.

"About the killer. I need your help," Y/N said, her voice regaining some composure as she took a seat on a nearby chair, her eyes finally meeting Jimin's as she explained the urgency of her mission.

"What help? Y/N, for God's sake, it's dang-" Taehyung began, his confusion evident as he tried to process Y/N's sudden plea for assistance.

"I know, but hear me out. If Jennie ssi won't survive, the next victim is Ryujin ssi," Y/N interjected, her voice urgent as she revealed the dire consequences of inaction.

"Huh? How are you so sure?," Jimin asked, his eyebrows furrowed in disbelief as he searched for answers.

"That's what I-" Y/N was interrupted by the shrill ring of her phone, causing her to pause mid-sentence and answer the call.

"Hello?" Y/N answered the caller, her voice slightly strained with anticipation.

"What is it, Yuna?" tension evident in her voice as she waited for a response.

"What?!" Y/N exclaimed, shock and concern evident in her tone as she processed the news delivered on the other end of the line.

"Ok," Y/N said quietly, the weight of the conversation settling in as she ended the call, her mind racing with thoughts of what needed to be done to prevent any further harm.

"What happened?" Jimin asked, his voice filled with concern as he watched Y/N's reaction to the phone call.

"Jennie ssi is dead," she replied quietly, her words hanging heavy in the air as the reality of the situation sank in.

"Y/N, what's this?" Taehyung inquired, holding out the locket that had fallen from her pocket during the phone call, catching her off guard.

"Oh, I got it from the killer. There's a photo of a girl in it," she explained, her voice tinged with a mixture of dread and determination. Taehyung carefully opened the locket to reveal the photo inside, his expression somber as he took in the image before him.

"No way..." Taehyung trailed off, his voice barely above a whisper, disbelief coloring his words as he stared at the photo in the locket.

"What?" Y/N asked, her confusion evident as she tried to grasp the gravity of the situation unfolding before her.

"Jimin!" Taehyung called out, beckoning him over to see the photo.

"The heck?" Jimin muttered, his eyes narrowing as he examined the image closely.

"What happened?" Y/N pressed, her desire for answers growing as the tension in the room thickened.

"This girl- you don't know her?" Jimin asked, turning the question towards Y/N, his expression expectant.

"How am I supposed to kn- wait, you guys know her?" Y/N's eyes darted between Taehyung and Jimin, realization dawning on her as she realized the depth of the connection they seemed to have with the mysterious girl in the locket.

"Tell her, Jimin," Taehyung urged, nudging his friend to share the truth with Y/N.

Taking a deep breath, Jimin spoke with a heavy tone, "It's... it's Jungkook's girlfriend," he revealed, the weight of the words hanging in the air.

Confusion washed over Y/N as she tried to comprehend the revelation. "Isn't she dead?" she asked, her voice filled with disbelief.

"How do you know that?" Jimin inquired, his curiosity piqued by the information Y/N possessed.

"He told me," Y/N replied quietly, her eyes downcast as she recollected the conversation she had with Jungkook.

"Actually, it was a suicide..." Taehyung chimed in, his voice filled with solemnity. "She jumped from the university building."

Y/N's eyes widened in shock, her heart sinking at the tragic revelation. "What? Why?" she asked, her voice trembling with a mixture of confusion and sorrow, desperate to understand the circumstances surrounding the girl's untimely demise.

"All we know is that she and Jungkook had a fight that day, and she used to get bullied..." Taehyung began, his voice filled with a mixture of sorrow and frustration.

"By any means, is the bullies the ones who are dead?" Y/N interjected, her mind racing to connect the dots.

"I have seen Irene bullying her a lot, then Sehun, Jennie- wait, it's them," Jimin said, his voice tinged with shock and realization. The weight of the truth settled heavily in the room as they collectively understood that the deceased individuals were indeed the bullies who had tormented Jungkook's girlfriend.

"So this is the missing puzzle, the reason is that they bullied her. But who is the killer?" Y/N mused, her brow furrowed in deep thought as she sought to unravel the remaining mystery.

"Are you thinking what I am thinking?" she asked, her gaze shifting between Taehyung and Jimin, hoping they were on the same wavelength.

"What? You are doubting Jungkook? It's not fair to do-" Jimin began, defending their friend before Y/N cut him off.

"No, I doubted him from the beginning," she interjected, her voice firm and resolute.

Surprised by her certainty, Jimin's curiosity sparked. "Why?" he inquired, eager to understand the basis for her suspicion.

FLASHBACK

Y/N's gaze swept through the lively crowd in search of Jungkook, only to be met with disappointment as he remained elusive. However, her attention was swiftly captured by the presence of a mysterious figure, shrouded in a cloak of secrecy. Clad in a complete black attire, he sat a few tables away, his eyes focused intently on a specific location, unrelenting in their unwavering stare. What truly captured Y/N's attention were his piercing blue eyes, their intensity resembling that of a predator preparing to strike its unsuspecting prey, a magnetic gaze that stirred a mixture of curiosity and caution within her.

In a sudden twist of events, the mysterious figure abruptly rose from his seat, striding purposefully towards the exit, seemingly chasing after someone. Y/N's curiosity ignited, fueling her desire to follow and unravel the enigma that surrounded him. However, just as she was about to embark on her own investigation, Yuna appeared, interrupting her train of thought.

"How could someone do something like this to her?" Y/N's voice was filled with a mixture of horror and anguish as she voiced her disbelief at the scene that unraveled in front of her. Every fiber of her being trembled, staring at Irene's motionless form.

"Everyone who dies is not innocent, Y/N," Jungkook whispered softly, sending chills down her spine.

Her search for Jin led her deeper into the quiet expanse, her eyes scanning the rows of bookshelves meticulously. Just as she was about to call out his name, a sudden collision sent her and a mysterious person crashing to the ground. Startled, she looked up, her annoyance evident in her voice.

"Yah, can't you see where you're going?" Y/N asked, her gaze locked on the person who had clumsily bumped into her. But before she could get a good look at him, he hurriedly scrambled to his feet and darted towards the library door, casting quick and nervous glances back at her. A feeling of curiosity mixed with unease washed over her as she watched him disappear, leaving her with unanswered questions.

'As Y/N turned around, she came face to face with Jungkook, a puzzled expression etched on his face. His quickened breath indicated that he had hurried to reach her.

"Um... Jungkook ssi?" Y/N responded, still trying to process the encounter with Sehun and the questions lingering in her mind.

"What are you doing here?" Jungkook asked, his brows furrowing with genuine curiosity and concern.

-

Just then, Jimin arrived, concern etched on his face as he inquired, "What actually happened here?"

"Did you see Jungkook ssi?" Y/N asked urgently, her focus zeroing in on a crucial point as she ignored Jimin's previous question, suspecting that Jungkook might hold the key to the unfolding mystery.

"No?" Jimin replied, his response tinged with uncertainty.

~

"Great, now what?" Jimin asked, his voice filled with a mix of concern and uncertainty as he processed the implications of their suspicions.

"Now what? We should see him," Taehyung suggested, his voice steady and determined.

Y/N's eyes flickered with a sense of urgency. "Yes, we need to confront Jungkook and get to the bottom of this. We have to find out the truth," she declared, her voice resolute.

They exchanged a determined glance, a silent agreement passing between them. They knew that they couldn't afford to waste any more time. Taking a deep breath, they steeled themselves for the difficult conversation that lay ahead as they prepared to confront Jungkook.
