My eyes always locked with a gorgeous girl.

Once, in a certain classroom, my eyes always locked with a gorgeous girl.
She was a loner. She always sat by herself in the furthest corner of the room. Every single day, she buried her face in books. At first, I figured she was just your textbook introverted bookworm.But boy, was I wrong.As it turned out, she was doing it on purpose. She just wanted to blend into the background. Honestly, it made sense. A few months later, after observing her school life for a while, I caught wind of the rumors still floating around. They said Cellia was easily one of the top three most beautiful girls in the entire school.Which meant, she was incredibly popular.The contrast between us couldn’t be sharper. Me? I was just the type of background student you’d find in some generic folklore. Not handsome, not a genius. Just a completely standard, average guy.However.Even though I thought reaching her was a total pipe dream, destiny had other plans.Every time I glanced at her beautiful eyes, she would look right back and smile at me. Her cheeks would flush bright red. I didn’t know if this was a sign that she actually liked me back.I was confused. Confused. Infused with confusion.Right when I was about to go completely insane from all the doubting and overthinking, Cellia suddenly left a note on my desk. She wanted to meet up. Just the two of us.I followed her. This was my shot. The best opportunities in life don’t knock twice, right?Yeah. Exactly."Izumi...""....."The spot was the staircase leading right out of the school. It was dead silent here. The other students had already gone home. It was just the two of us.I had absolutely no idea how to start.Ugh.She only called my name and froze.Ah, damn it!Shit. I shouldn't be acting like such a pathetic wimp! I’ve liked her for the longest time! I have to confess to her right here, right now.Alright. Let's do this."...Cellia!"I called her name and backed her up against the corner of the stairs. My face was way too close. I could clearly feel her uneven breathing. Once again, her cheeks turned bright red."I... honestly, I’ve liked you since the very beginning! Please go out with me!"I blurted it out.But I kept my eyes squeezed shut. I guess I was just terrified of getting rejected.Ahhh!My heart was pounding way harder than usual! Even compared to running a morning marathon, this thumping was on a whole different level! Hell.So this is what a first confession feels like."I-Izumi...?"I heard her voice! She was clearly nervous. But I still couldn’t bring myself to open my eyes."....Y-yeah!?""About that.... You can't right now."That was when I opened my eyes. I saw Cellia looking at me with half-lidded eyes. She was obviously embarrassed but trying her best to hide it."But—!""Shh!"Her slender index finger pressed against my lips. The slight sweat on her finger tasted salty. My eyes widened, and I felt like my heart was about to leap out of my chest."Maybe after graduation. Yeah, after graduation.""....."Before I could say another word, Cellia slipped out of my grip. She walked away just like that, leaving me there half-dead from the tension.Whew.And here I thought I was going to get brutally rejected. If she phrased it that way, it meant I still had a chance."....After graduation, huh?"I thought about it the whole way home. Day after day. Month after month. Until finally, graduation day arrived.I actually made it through school. And during the photo session, I dragged her right back to the staircase where I first confessed. This time, there was no rejection. I didn't even need to bring up her old promise.She said it herself."Izumi... thank you so much for waiting for this day."And just like that, we were officially dating.Yep. We were a couple. Our first few dates took us to all the popular spots. Cafes, movie theaters, parks, and we even took a trip down to Okinawa.Everything paid off. It wasn’t a waste of time to summon my courage back then. Honestly, I’m kind of a big deal, aren't I? Securing a girl who ranks third among the school's beauties is no small feat.

One day, a loud knocking on my door woke me up. Guests rarely ever came to this apartment. At most, it would just be a delivery guy....Or could it be...No way. That should be impossible!"B-but... it might actually be her!"Yep, that's just how I am, constantly fighting my own doubts. I threw off the covers, scrambled out of bed, and rushed to the door with pure excitement.Peeking through the tiny peephole, I saw Cellia standing there, dressed up beautifully. What was going on? Why the sudden surprise visit? This was the first time she had ever come over to my apartment.I quickly opened the door, trying to act casual. Sure, I forgot to wash my face and didn't even bother to fix myself up, but I still had full confidence in my natural look."Good morning, Izumi!"I let out a soft chuckle and scratched my head. What a warm greeting."Ah, morning. By the way, what brings you here so suddenly?""Hm? Suddenly? I sent you a text a few hours ago.""Eh, really??"Huh."I haven't checked my phone yet. My bad.""It's fine..."Before I could even invite her inside, Cellia suddenly closed the distance aggressively. What the hell? This was completely out of character. She shouldn't be this forward.My back hit the wall behind the door. Our faces were inches apart. I ended up tripping over my own feet from the sheer shock of it. She...Cellia crawled right on top of me.That smile on her face..."C-Cellia...!?"I tried to snap her out of it, but it was already too late.Yeah. Way too late.She slammed her lips onto mine in a fierce, wild kiss!Shit!I couldn't move. It felt exactly like being pinned down by a wild predator.Just as I was about to get swept away by the moment, a sensation resembling a lightning bolt struck vividly inside my head. A sudden flash of light. It was hard to put into words.But one thing was certain, I suddenly remembered something that I absolutely should not have remembered.
A brutal war. Blood dripping down. A massive black hole magic circle engraved perfectly in the sky. A spell of my own creation.
And standing right in front of me, a woman clad in heavy metallic armor drove the legendary sword Ragnarok straight through my heart.She was..."....Cellia...!?"".....!!"The moment I gasped out that name, Cellia instantly recoiled from me. She covered her lips, which were still wet from the kiss. Her eyes were wide with sheer disbelief.It looked like she had just experienced the exact same thing. A flood of lost memories hitting all at once."....W-wait!"Before I could confirm whether she truly was the Hero from my past life, she turned around and bolted out the door, leaving absolutely nothing behind.How on earth did things turn out like this?Who exactly am I? In those memories, I was Satanos. The Supreme Demon King who ruled over the realms of darkness. 
Yet, I ended up dying at the hands of the very woman I love, Cellia.
