Beneath Their Devotion (Yanderes x Reader)

8. Obsidian Death

Yuna's dorm room was buzzing with energy, a blend of excitement and nervousness. The lights strung across the walls cast a warm, flickering glow over the room's mismatched decor. On the bed lay a collection of makeup brushes, jewellery, and fabric swatches that Yuna had discarded in her frenzy of indecision.

"Hold still," Yuna muttered, stepping closer to Y/N with a lip gloss wand poised like a weapon.

Y/N leaned back, waving her hands in surrender. "Yuna, seriously, I don't need—"

"Yes, you do." Yuna's hair swung as she stepped closer, determination flashing in her eyes. "You look great, but a little gloss will make you look stunning. Trust me."

Sighing, Y/N relented, lips parting slightly as Yuna applied a shimmery coat. The silky white gown Y/N wore hugged her frame, its lace sleeves clinging delicately to her arms. The gown's simplicity contrasted with Yuna's outfit: a light pink dress with an intricately beaded neckline that sparkled each time she moved. The colours highlighted her warm complexion, making her look every inch the confident socialite.

After receiving verbal confirmation from Haru and Ren, the girls had both gotten paper invitations to the event. The dress code was, not surprisingly, formal.

"Okay, now look." Yuna turned Y/N toward the mirror.

Y/N blinked, surprised at the subtle but noticeable difference. "You're scary good at this."

"Duh. You should've seen me back in high school," Yuna said, tossing the lip gloss onto the cluttered desk. "I was the unofficial stylist for our entire grade."

Y/N was about to tease her when the door flew open with a loud thunk. Hayato stood in the doorway. His expression quickly changed from lighthearted to severe when he spotted them in their dresses, his eyes sharp as they darted between the two of them.

"What the hell is this?" he asked, his tone a mix of disbelief and irritation. His gaze lingered on their dresses before his brows knitted into a deep frown.

Yuna rolled her eyes, placing a hand on her hip. "Nice to see you too, brother."

"What are you two doing?" he demanded, stepping into the room.

Y/N raised an eyebrow, her nerves prickling. "Getting ready for the event," she said, her voice even. This reaction was to be expected. Though they had hoped he wouldn't find out about their plan at all.

Hayato's frown deepened. "The Obsidian Circle event?" He glanced pointedly at their gowns, his disapproval palpable. "You're actually going?"

"Yes, actually," Yuna shot back, her tone dripping with sarcasm. She turned back to the mirror, adjusting her earrings. "Not that it's any of your business."

"It is my business when you're walking straight into something dangerous."

"Dangerous?" Y/N interjected, interested in any information that could help her understand Mika better. "It's just a social event, isn't it?"

Hayato's gaze snapped to hers, his jaw tightening. "Maybe now it is, Y/N. But, once they pull you in, it's not easy to get out. You think you're in control, but you're not."

Before Y/N could tell him their real goal was not joining the Circle Yuna interjected.

"Ugh, here we go," she muttered under her breath, spinning to face him fully. "You sound like a broken record, Hayato. Just because you don't like the Circle doesn't mean you get to scare us into avoiding it."

"I'm not trying to scare you, Yuna," he said, his face softening. "I'm trying to protect you. You don't know what you're getting into."

"Protect me?" Yuna scoffed, crossing her arms. "You're not my dad. And for the record, I can handle myself."
