The alarm blared through the house, its relentless sound cutting through the early morning calm. Everyone was scrambling, rushing to don their suits and gear for the mission. I was already dressed, but my mask was nowhere to be found. I checked my desk, looked under my bed, and retraced my steps with mounting frustration. Then it dawned on me—I'd let Vanya try it on recently. She'd been so excited about it, and now I needed it back.

I bolted out of my room, the alarm still ringing in my ears, and sprinted down the hallway. Luther zoomed past me, clearly in a rush. I reached Vanya's door, knocked briefly, and pushed it open. Inside, I saw her sitting at her desk, absorbed in whatever she was holding.

"Hey, Vanya, do you still have my mask?" I asked, my voice carrying over the alarm's din.

She looked up, a smile spreading across her face. "Yes, I have it right here." She walked over to her desk and retrieved the mask from a drawer, handing it to me with a slight grin.

As I took the mask, my attention was drawn to a black violin case open on her bed. My eyes widened in surprise. "Wow, you got a violin?" I asked, walking over to it and admiring the elegant instrument with genuine awe.

Vanya's face lit up with pride. "Dad gave it to me. After my music lesson last week, I asked if I could learn to play, and he said I could keep it."

"That's incredible!" I said, gently running my fingers over the smooth surface of the violin. "I didn't know you were into music."

"I want to be extraordinary," Vanya said softly, her gaze fixed on the violin with determination.

I smiled at her enthusiasm. "Well, I don't know much about musical instruments, but I'm sure you'll be amazing with this."

Just then, we heard a throat clear from the doorway. Dad stood there, his stern look a clear reminder that it was time to leave. He turned and walked away, leaving us with the sense of urgency hanging in the air.

"Well, I guess it's time for me to go," I said, turning back to Vanya.

"Okay, be careful," she said, handing me my mask. I slipped it on, adjusting it over my eyes.

"Always," I replied, giving her a reassuring smile. I hesitated at the door, then turned back to her. "Hey, V. Maybe after this mission, you could teach me how to play the violin sometime?"

Vanya's eyes brightened, and she smiled warmly. "I'd like that."

With one last nod, I dashed down the hallway to meet my family, ready for the mission ahead. As I left, I felt a mixture of anticipation and excitement, looking forward to the day when Vanya's music would become a new, beautiful part of her life.

________________________________

It had been a month since I'd last seen Vanya's violin, and today I found myself sitting in Klaus's room, enjoying a bit of downtime. Klaus and Ben were deeply engrossed in a game of Battleship, their competitive banter filling the room.

"B, 10," Ben declared, his voice hopeful.

"Miss," Klaus replied with a smirk.

"That's three in a row," Ben said, his frustration growing. "You're cheating."

"I'm not," Klaus retorted, still grinning. I laughed at their playful argument, finding their back-and-forth quite entertaining.

Ben, clearly desperate for an advantage, turned to me. "Y/n, look into his eyes and see his board."

"Don't listen to Ben. He's just being dramatic," Klaus said, his smile widening.

Feeling a bit mischievous, I decided to take up Ben's challenge. I leaned closer to Klaus and focused on my powers, channeling them to extend my perception. I locked eyes with him, and as I concentrated, his eyes darkened to a deep, opaque black. For a moment, everything around him seemed to blur, and I saw through his perspective.

In Klaus's vision, the Battleship board appeared as a blank slate. No ships were visible, just an empty grid. "Klaus didn't even put down his ships!" I exclaimed, unable to contain my laughter. "He's been playing with an empty board!"

Klaus, still under my influence, looked around in confusion. "Y/n, give me back my vision!" he protested, his voice a mix of panic and amusement.

Ben grinned triumphantly. "I knew it! Klaus was definitely cheating!"

From my vantage point, I could see Klaus's face contorting in bewilderment as he tried to make sense of the world around him. His vision, now entirely in my control, showed me everything he saw—or rather, everything he wasn't seeing. The blank board was a clear giveaway that he had been playing unfairly.

I couldn't help but revel in the playful deception as I held his vision hostage for a moment longer. Finally, I withdrew my powers, allowing color and clarity to return to Klaus's eyes. He blinked rapidly, his sight coming back into focus as he adjusted to the change.

"Okay, okay," I said, still chuckling. "You were right, Ben. Klaus was definitely cheating."

Klaus groaned, shaking his head in mock indignation. "Fine, you got me. But I swear, I'll get you back for this!"

Ben and I exchanged amused glances, enjoying the light-hearted break from our usual routine.

Klaus and Ben resumed their game, their earlier argument fading as they focused on their strategic moves. But soon, we were all distracted by a soft, melodic sound drifting through the house. Vanya was playing her violin, and I had to admit, it was beautiful. It amazed me how quickly she had picked up the instrument and how skilled she was already.

"She's still playing with that thing?" Ben commented, his voice barely masking his irritation at the sound.

"She's been making noises on that trumpet for a whole month," Klaus chimed in, clearly frustrated.

"It's a violin," Ben corrected, bewildered by Klaus's mistake.

"They're both instruments that make noises," Klaus replied dismissively.

Ben shot him an exasperated look, clearly unimpressed by the comparison.

"Give her a break, guys. Vanya never had anything to do for herself until Dad gave her the violin," I interjected, defending my sister. I couldn't help but feel proud of her progress.

"Well, that violin is making me lose my train of thought trying to beat Ben," Klaus said, adjusting himself on the floor with a huff.

I scoffed and smiled, unable to resist the pull of Vanya's music. It was a welcome distraction from our usual chaos. I got up from Klaus's chair and made my way toward the door.

"Where are you going?" Ben asked, setting his game pieces for a new round.

"To hang out with Vanya. Try not to continue fighting," I said, raising an eyebrow at them both. I opened the door and left, closing it behind me.

As I walked down the hall, the music grew louder and clearer with each step. The sweet, haunting notes of the violin guided me to Vanya's room. I could hear the passion in her playing, and it made me smile. The sound was a stark contrast to the usual clamor of our lives, a soothing balm in the midst of our hectic existence.

I reached her door and paused, taking a deep breath before knocking gently. The music continued, undisturbed. I opened the door slowly and peered inside, seeing Vanya standing by her window, completely absorbed in her playing. Her eyes were closed, and her fingers moved gracefully across the strings.

"Hey, Vanya," I said softly, not wanting to interrupt her.

Vanya looked up, a smile lighting up her face as she saw me. She continued to play, her eyes sparkling with joy. "Hi, Y/n."

"It sounds amazing," I said, stepping further into the room. "I can't believe how much you've improved in such a short time."

Vanya beamed with pride. "Thank you. I've been practicing every day. It feels good to finally be able to play something beautiful."

I watched Vanya continue to play, the melody weaving through the room like a gentle breeze. Her talent was undeniable, and I felt a swell of pride at how far she'd come. I settled onto her bed, the soft hum of her violin filling the space with a serene atmosphere.

As I listened, I remembered our conversation from before my mission—when I'd suggested that maybe, someday, she could teach me how to play the violin. I had hoped it would give her a chance to share her passion, and I was eager to learn from her.

"Hey, Vanya," I said, breaking the silence.

She slowed her playing and set her instrument aside, turning her full attention to me. "Yeah?"

"Do you remember when I said maybe you could teach me how to learn the violin sometime?" I asked, hoping she would recall.

She nodded, her face lighting up with recognition. "Yeah, I remember that."

"Is that offer still available?" I asked, my heart beating a little faster at the prospect of learning from her.

"Of course," she said, her smile widening. "I'd love to teach you."

"Great," I said, standing up from her bed with enthusiasm. "How hard could it be?" I added with a grin, feeling a surge of excitement at the thought of starting this new journey with Vanya.

Her smile was warm and encouraging, and I felt a renewed sense of anticipation. As I looked at her, I realized how much this meant to both of us—not just the learning, but the connection it would bring. It was a chance for us to bond in a new way, and I was eager to take on the challenge.

_______________________________

And I was wrong—it was hard.

An hour had passed, and I was standing in Vanya's room, struggling with the violin while she observed from her bed. Every time I moved the bow across the strings, the notes that emerged were nothing like Vanya's—sharp, squeaky, and far from melodious. I could see the effort it took for her to keep a straight face as she watched me fumble.

I made another unpleasant sound and stopped, looking up at her with a sheepish grin. "I think it's broken," I joked, trying to lighten the mood.

Vanya chuckled softly. "No, it's not broken. You're just learning. It's not hard—just practice," she said, her voice soothing and encouraging.

"Says the person who plays beautifully and perfectly," I replied, handing the violin back to her.

"Like I said, it's practice," she countered. "You think I got it right my first time?"

"Did you?"

I raised an eyebrow, waiting for her to respond. When she didn't, I knew she didn't struggled as much as I was. "Figured," I said with a laugh, and we both shared a light-hearted chuckle.

Her laughter was comforting, and I could see how much she appreciated the effort I was putting in. Despite my struggle, I was grateful for her patience and encouragement.

"I think maybe musical instruments aren't for me," I said with a shrug, feeling a bit defeated after struggling with the violin.

Vanya shook her head with a reassuring smile. "No, it's just about practice. You're doing great; you just need more time. Here, let me help you." She gently placed the violin back on my shoulder, guiding my hands to the correct positions. Her fingers lightly adjusted mine on the strings, demonstrating how to hold them properly.

"Okay, so when you move the bow, keep it steady," she instructed, stepping back to watch me. Her eyes were full of patience and encouragement.

I nodded and gave it another try, but the sound that came out was still harsh and squeaky. I winced at the noise.

"Okay, now, do you see where there was a little mistake?" Vanya asked, her tone gentle yet instructive.

"Yeah. Your violin hates me," I joked, trying to lighten the mood as I handed it back to her. She laughed softly, a bright, warm sound that made me feel a bit better.

"No, it's not that. When you move the bow, you need to adjust your fingers to make the sound clearer. And keep the violin steady," she explained, pointing to each of my fingers. "Like this." She demonstrated the movements again, her touch guiding mine.

"Alright, I think I've got it now. Let's see if I can get it right this time," I said, taking a deep breath. I moved the bow again, adjusting my fingers as she had shown me. This time, the sound was much smoother. I looked at Vanya, who was watching with a proud smile.

"Holy shit, that came out amazing," I said, feeling a wave of joy and relief.

"That sounded amazing, Y/n," Vanya said, stepping closer. "See? Nothing like a little practice will always make you come out on top." Her voice was encouraging, and her smile was genuine.

"Well, maybe that was just luck. But I definitely couldn't have done it without your help, Vanya," I said softly, my gratitude evident in my tone. She smiled warmly, her eyes reflecting a mixture of pride and happiness.

In our family, Vanya had always been treated as an outsider because she didn't have powers. Father had left her out of missions and photos, and it often felt like she was overlooked. But now, seeing her embrace her talent and feeling special, I was glad she finally felt recognized.

I handed her the violin, and she took it with care, placing it back in its case.

"I'm sure you enjoyed the small lesson," she said, closing the case.

"Small?" I raised an eyebrow. "You've taught me so much already."

"Well, you know how to use it now, and I'm sure you won't need any more lessons," she said, her tone casual but with a hint of uncertainty.

"Who said I didn't want more lessons?" I asked, a teasing edge in my voice. Her eyes widened in surprise.

"You want to learn more?" she asked, clearly taken aback.

"Duh! And I want you to teach me," I said with a grin. "I want to learn everything you know. It's not just about playing the violin; it's about learning from you."

She looked at me, her expression softening. "You really want that?"

"Absolutely. And I want to learn how to control my notes, maybe even master some songs. One day, I'll buy my own violin, and we can play together," I said with enthusiasm.

Vanya's eyes lit up with happiness, and she stepped closer, a mix of surprise and delight on her face. "Y/n, you don't have to—"

"And one day," I cut her off, "I'll see you play on a big stage with that same violin, and I'll be right there in the front row, cheering you on."

Her smile widened, and she moved forward to hug me. I embraced her tightly, feeling a deep sense of connection. Vanya, despite everything she'd been through, was special to me. She felt like a true sister, not just by blood but in every way that mattered. I couldn't wait to continue learning from her and supporting her dreams.

We stood there for a moment, holding each other, content in the shared understanding that our bond went beyond family—through talent, support, and the promise of a bright future.
