Natsuki x (Y/N): Shadows of the Past {Remastered}

Chapter 4: Growth and Regret

Your POV
She spent a while crying till she eventually calmed down, though I looked at the time and realized we had to go, it was 5:36 and clubs ended about 6 minutes ago but Natsuki was asleep leaning on me and she looked so cute I didn't want to wake her up, for a few seconds, I felt like petting her, and now that I'm doing so, I seriously don't want to stop, but she eventually felt what was happening since she woke up blushing, I kinda freaked out when she looked at me but I felt my cheeks being red as soon as we stared at each other.

"Y-You're awake now?, d-did-did you sleep well?" I asked stuttered, I honestly don't know what went through my head a few seconds ago but I couldn't think about it now, the nurse wasn't coming back either so I can only assume she had left Natsuki here by herself for a while, "Yeah, I did, it wasn't long but, that was the first time I've had a peaceful nap in ever" She had responded my question with a smile on her face and I couldn't help but feel both glad and shy about it. "Natsuki, it's already time to leave, the nurse hasn't come back so, I'll take you home", "T-thanks, I-I appreciate it..." She said so still blushing, I swear, why does she have to be this cute...
"Can you walk?" I asked because I had to make sure, there's no harm in trying to play it safe, "I don't know, my leg's still broken so I'm not sure I'll be walking on my own anytime soon" she said, which suddenly reminded me of something, I remember having that vital that my brother gave me, honestly even now I'm not sure why I'd always kept on carrying it, though, now that I think about it...

Flashback/ 2 years earlier
I don't know what's so important he called me down here but I'm guessing it has to be 'Important', and it better be, if it was worth waking up at 4 in the morning on a friday.
"HERE YOU GO, MAKE SURE YOU ALWAYS CARRY THAT WITH YOU!" He said loudly as he handed me what looks like a, syringe?, holding..., I've got no idea, "So, what exactly is this is supposed to be?" I just had to ask, cause for all I know perhaps he may want me dead, if anything I once heard from dad that he was quite happy as an only child so, maybe this is it "AN ACCELERATION STIMULANT" He said, he said that and I've still got no idea what it even is, "A what?", "AN ACCELERATION STIMULANT, ONE OF MY FIRST ATTEMPTS AT AN ORIGINAL MEDICINE, YOU KNOW HOW THE HUMAN BODY HAS ITS OWN HEALING PROCESS?"
"Yeah?", "WELL THIS IS GOING TO ACCELERATE IT, SPEAKING THEORETICALLY"
"The name is ironic then, why call it an accelerated stimulant if you're not even sure it'll heal someone that instantly, besides what can it even do, or better yet, does it even work the way it's supposed to?, sometimes I wonder if he even checks his damn math"
"WELL, IF MY THEORY IS CORRECT, SO FAR IT CAN ACTUALLY ACCELERATE THE HEALING OF PHYSICAL INJURIES, AND IT DOESN'T DISCRIMINATE EITHER, ANY PHYSICAL INJURY CAN BE TREATED THOUGH THE PROCESS COULD END UP VARING DEPENDING ON THE SORT OF INJURY" he said that like it bearly mattered to him, does he even realize that if it really works, this could make him a millionaire of sorts, but that actually remains to be seen, "If you've got no lab rat to even test this on, why bother dealing with all of it anyway?, I don't think you'll have much use for this and neither will I so-" "Take it, you're going to need it at some point" He said so without that loud tone of his, and if there's one thing I know is that if William speaks normally like the rest of us, he's being fully serious, "All right, what if it fails though?, even you could make a mistake or two and you can't deny it"
"It won't, it's a prototype and too weak for actual damage, trust me" how could I not trust him, especially after telling me that with a normal tone in his voice, William, for 8 years had never once lowered the loud tone he usually speaks with and whenever he did, it was always at a point where something very important happened and that was something we trusted so, therefore I trust him on this...

Present day/ Your POV
I took out the syringe I still held in my book bag and seriously prayed to god this would even work, not that I don't believe in my brother but rather he doesn't always make sure everything works the way he says it had to, but he's a Stark, I'll place my faith on you here and now bro, please let this work, "Natsuki, I'm not sure if this could help but here, it's a, special sort of, something that can probably heal you up, I've never had much use for it myself but you can have it, of course I can understand if you refuse it as well, it kinda came out if nowhere and it looks very suspicious doesn't it?" I said so without looking at her so much, mostly because I was afraid of what she'd think, yet for all my worries, she just kept on looking at it, "What is it?" She asked, "It's an acceleration stimulant, or at least that's what my brother calls it, ignoring his scientific mumbo jumbo, it's somewhat similar to a medical injection, just more advanced and, unexplainable" I explained as best as I could, William was always better with this stuff than I was, truth be told no matter how I look at it it's suspicious, no such thing as an all-powerful healing stim should exist and yet, my brother is living evidence that apparently, nothing is impossible for humankind.
