Glitter in the Den of Wolves

The morning sun at Eunjang High School didn’t feel warm; it felt oppressive, reflecting off the grey concrete and the grim faces of boys who looked like they had forgotten how to smile. However, walking through the gates with a rhythmic bounce in her step and a designer bag slung over her shoulder, [Name] was a stark contrast to the gloom. She wore the boys' uniform blazer, but she had tailored it to fit her frame perfectly, and her pleated skirt—which she had insisted was a "fashion choice" despite the school's confusion—fluttered in the breeze.

"Oh my gosh, the lighting today is literally everything!" [Name] chirped, holding up her phone to check her reflection in the camera. She adjusted a stray strand of her perfectly curled hair and applied a layer of strawberry-scented lip gloss. "I look so cute. Right, Si-eun?"

Yeon Si-eun didn’t look up from his textbook. He sat at his desk, his posture rigid and his eyes cold, staring at a complex mathematical equation as if it were an enemy he needed to dismantle. But as [Name] leaned closer, the scent of her perfume—something sweet and expensive—invaded his personal space. His hand tightened around his pen until his knuckles turned white.

"You’re blocking the light," Si-eun said, his voice a low, clinical monotone.

"You're always studying! You're going to get wrinkles if you frown that much," [Name] giggled, completely ignoring the dangerous flicker in his eyes. She reached out and poked his forehead with a manicured finger. "See? Relax! You should come shopping with me after school. I need a second opinion on some heels."

The classroom went silent. The other students watched with bated breath. Nobody touched Yeon Si-eun. The last person who had tried to annoy him ended up with a ballpoint pen through their hand. But Si-eun just stared at [Name]. His gaze wasn't filled with the usual calculated violence; it was something deeper, a quiet, possessive intensity that she was too bubbly to notice.

"I have cram school," Si-eun muttered, though his eyes followed the movement of her glossy lips.

"So boring!" [Name] pouted, twirling a lock of hair.

Behind them, Park Hu-min let out a loud, boisterous laugh, slamming his hand down on his desk. "Hey, Sparkles! If the nerd won't go, I will. But only if we get burgers after. I'm starving."

"Hu-min! You’re so sweet!" [Name] turned around, beaming at him. "But you have to hold my bags. I’m planning on buying a lot. My dad gave me his card because I told him I was feeling 'spiritually drained' by this school."

Go Hyun-tak, sitting nearby, rolled his eyes but couldn't hide the faint flush on his cheeks. "Spiritually drained? You’ve been here for a week and you’ve already turned the back of the classroom into a vanity station. There’s literally a ring light clipped to your desk."

"It’s for the aesthetic, Hyun-tak! You wouldn’t understand," she teased, sticking her tongue out at him.

Hyun-tak grumbled something under his breath about "annoying girls," but his eyes were glued to her. He found himself constantly checking the perimeter of the room, his muscles tensed to jump at anyone who even breathed in her direction. He didn't realize it was a protective instinct; he just knew that the thought of anyone else looking at her made his blood boil.

The peaceful, albeit strange, atmosphere was broken when the door swung open. Oh Beom-seok walked in, looking pale and jittery. He stayed close to the walls, his eyes darting around until they landed on [Name]. A strange, sickly sweet smile spread across his face.

"I got you the drink you liked," Beom-seok said, hurrying over to her desk. He placed a specialized peach tea from a cafe three blocks away on her desk. "The one with the extra pearls."

"Aww, Beom-seok! You’re an angel!" [Name] clapped her hands together, taking the drink. "How did you know I was craving this?"

"I remembered you mentioned it yesterday. At 2:14 PM," Beom-seok replied softly. His eyes were wide, fixed on her with an unnerving focus. He had a notebook in his bag filled with similar details—her favorite colors, the brands she liked, the exact way she laughed when she was nervous.

"You have such a good memory," she said, taking a sip. "You're like, a total bestie."

Beom-seok’s smile twitched. *Bestie.* He didn't want to be a bestie. He wanted to be the only thing she looked at. He wanted to lock her in a room where the only light she had was the glow of her own phone, away from the prying eyes of the thugs in this school.

As the morning progressed, the tension in the room grew. It wasn't the usual tension of a looming fight, but a silent war of territory. Every time [Name] laughed, the boys around her would glance at each other, their expressions darkening. They were like predators circling the same prize, yet [Name] sat in the middle of the storm, humming a pop song and scrolling through a fashion blog.

During lunch, the group relocated to the roof—a spot usually reserved for the high-ranking fighters. [Name] sat on a discarded crate as if it were a throne, chatting away about the latest skincare trends.

"And then he told me that I couldn't wear pink to the funeral, and I was like, 'Why? It’s a celebration of life!'" [Name] laughed, tossing her head back.

Ahn Su-ho, who had been napping against the railing, opened one eye. He leaned over, resting his chin on his hand as he watched her. "You're a real piece of work, you know that?"

"Is that a compliment? I'll take it as a compliment," she said, winking at him.

Su-ho reached out, his large hand hovering near her face before he settled for tucking a loose strand of hair behind her ear. His touch was lingering, far longer than necessary. "Just stay close to us, okay? This school isn't like the ones in the movies."

"Oh, I know! Everyone is so grumpy here," she sighed. "But you guys are so nice to me. I think I'm making a good influence on you."

Seo Jun-tae, who was sitting on the floor nearby, looked up from his tablet. He had been quietly tracking [Name]’s social media footprints, ensuring no "creeps" were commenting on her photos. Of course, he didn't count himself as one. He was her "digital guardian."

"There are some dangerous people in the vocational department," Jun-tae warned, his voice trembling slightly. "Na Baek-jin... he's been asking about the 'new girl' in Eunjang."

[Name] gasped, her eyes widening. "Is he handsome? I heard he has really cool hair."

The air on the roof suddenly turned cold. Park Hu-min’s grin vanished. Si-eun’s eyes snapped toward her, his gaze sharp enough to cut glass.

"He's a monster," Si-eun said, his voice dropping an octave. "Don't ever speak his name."

"Yikes, okay! Touchy subject," [Name] said, putting her hands up in a playful surrender. "I’ll stick to my favorite Eunjang boys. You guys are much cuter anyway."

The compliment did little to soothe them. The mention of Na Baek-jin was a reminder that they weren't the only wolves in the city.

The school day ended, but the shadows were already lengthening. As [Name] made her way toward the exit, she realized she had forgotten her favorite lip gloss in the classroom.

"Oh, shoot! I'll be right back, guys! Wait for me by the gate!" she called out to Su-ho and Hu-min, who were arguing about where to eat.

She hurried back into the empty hallways. The silence of the school at sunset was eerie, but [Name] was too busy thinking about whether she should buy the silver or gold glitter for her nails. She reached the classroom and grabbed the gloss from her desk, but as she turned to leave, she found the doorway blocked.

It wasn't one of her friends. It was Geum Seong-je. He stood there, his long coat draped over his shoulders, a wicked, amused smirk on his face. He was one of the Union's most feared members, known for his unpredictable cruelty.

"So, you're the one everyone's losing their minds over," Seong-je said, stepping into the room. He moved with a feline grace, closing the distance between them until [Name] was backed against a desk.

"Um, hi! You're really tall," [Name] said, looking up at him with genuine wonder. "Are you a model? You have the bone structure for it."

Seong-je paused, his smirk faltering for a split second. He was used to girls screaming, crying, or trembling in his presence. He wasn't used to being scouted for a modeling agency. He reached out, grabbing her chin and tilting her head back.

"Do you even know who I am?" he hissed, his thumb brushing against her lower lip.

"A very handsome guy with a bit of an attitude problem?" [Name] guessed, her heart fluttering—not out of fear, but because she thought this was like a scene from a K-drama. "You should really smile more. It would help your brand."

Seong-je’s eyes darkened. He leaned in close, his breath hot against her ear. "I could break you in half right here, and no one would stop me. Your little 'protectors' aren't here."

"But why would you do that? My outfit is too cute to be ruined," she said, pouting. "And besides, I think you're just lonely. Do you want to come shopping with us? We're going to the mall!"

Seong-je stared at her, genuinely baffled. Her naivety was like a shield he didn't know how to pierce. He felt a strange, primal urge to snatch her away, to hide her from the Union and Eunjang alike, just to see how long it would take for that bright, stupid smile to break.

Before he could respond, the classroom door was kicked open with such force it hit the wall with a deafening bang.

Yeon Si-eun stood there, his eyes devoid of any humanity. Behind him, Su-ho and Hu-min looked ready to commit murder.

"Get your hands off her," Si-eun said. It wasn't a request.

Seong-je let go of her chin, laughing softly as he stepped back. "Relax, Eunjang's White Mamba. We were just talking about fashion."

[Name] ran over to Si-eun’s side, grabbing his arm. "Si-eun! Look, I found a new friend! He has great cheekbones!"

Si-eun didn't look at her. He kept his eyes locked on Seong-je. "If you touch her again, I won't just beat you. I'll make sure you never wake up."

The threat was heavy, vibrating with a dark, yandere obsession that would have terrified anyone else. But [Name] just squeezed Si-eun’s arm and giggled.

"Oh, you guys are so protective! It’s like I’m a princess or something," she beamed, completely oblivious to the fact that the boys around her were ready to tear the world apart just to keep her in their sight. "Now, come on! The sale at the mall ends in an hour, and I really need those shoes!"

As she led the group of lethal, obsessed delinquents out of the school, she chattered away about glitter and gloss, never noticing the way they watched her—like she was the only light in their violent, dark world. And they would make sure that light never went out, no matter who they had to kill to keep it burning.
