Serene Days | Chapter 1: Why Do You Make Me Feel This Way?

by: RealTAP

Kyousuke:

A wave of nostalgia brushed over me as I uttered the same old words I had always relied on to ensure my little sister that I was there for her. The words themselves weren't really special, and when I said them it didn't mean much to me other than what was intended. It wasn't the case for Kirino though, it was evident that the phrase meant so much to her. Her ocean-blue eyes sparkled as if I were at the beach watching the real deal.

She sat upright on the couch and flashed me a cheery smile. It was very unfamiliar, and I'm sure my mouth was still open in surprise. I didn't detest it though, in fact, she should smile like this more often instead of frowning which in truth over the past weeks has happened.

Honestly, I'm shocked and not shocked at the same time. I was usually surprised by such occurrences as I got used to getting insulted by my sister left and right before the first-ever life counseling session. Following the initial shock, I'd feel all normal again, as since then, me and Kirino have gone through and done a lot of stuff together. I hope it wouldn't be out of line for me to think that she has mellowed up a bit towards me. It'll take a little longer to get completely used to it, but it was certainly welcome.

Kirino then suddenly got up and started walking back up to her room with pace. She took a suggestive glance at me before disappearing into the hall and up the stairs, leaving the door open behind her. I then walked up the stairs myself before taking a quick pit stop at my room to hang my coat before advancing and halting right in front of Kirino's door.

Usually, this location in the house is where I contemplate the impending doom that could occur on the other side. Many hesitations have occurred at this spot, caused by the wild events that have happened in that room. Before, I'd be much more hesitant to enter her domain, thinking that no matter what I did I'd exit a battered man. Now though, I'm much more calm, knowing now that reason is within my sister after all. Something bad might happen but that's just how the world works so I'm sure it'll be fine in the end. With that deduction, I knocked on her door.

The door opened softly and slowly, and Kirino peaked only her cute, little head out of the small gap. She took a good look at me like a mouse peeking out of a hole before blushing and scurrying back to her chair inside. What the heck was that? So cute. After that odd ordeal, I entered her premises and sat on the carpet as usual. I'd usually stand first to determine how long I'd be there for, and what course of action would be most appropriate if she hadn't given me an order already, but I was feeling rather lazy today so I just merely sat.

Kirino turned to face me on her chair and so I turned to match. The direct eye contact seemed a bit too much for her though, as she quickly looked away with a rosy hue imprinted on her face again.

"Well? What do you need my help for Kirino?". I smiled in a relaxed manner to her, maintaining a rather calm atmosphere. Kirino looked back at me for a second then quickly changed to staring at the window again, evidently still blushing.

"I-i've been meaning to ask you something" she replied, still gazing outside the window. It seemed that whatever she was about to ask embarrassed her to some extent. I quickly took the time to examine her long, flowing hair while waiting for her to muster up her courage. The sunlight peering in the room through the window emphasized her beauty, her light brown hair almost glistening. It was a sight to behold as, despite her embarrassment, she was still able to look so pretty. No wonder she's a model.

"W-well, you see…" Kirino spoke up, "A… uh… A-a". It was a rare sight to see Kirino stuttering like this, it made me all the more intrigued to find out what delicate topic has got her tongue like this.

After trying to mutter and whisper out words to no success, Kirino finally took a deep breath and closed her eyes. "A-a new member is joining the group!". She shouted the words directly to me with significant force and volume. After huffing for a bit Kirino finally looked at me.

"T-there's a new member with the username: whiterabbit25 who Saori was chatting with recently on her forum wall, it appears that they'll be coming to our next meet tomorrow". I perked up with interest. A new member huh? Now that I think about it, it's been just me, Kirino, Kuroneko, and Saori since that initial first meeting ages ago.

My attention was recalled as Kirino began speaking again, still in a somewhat embarrassed tone, "Y-you see, I haven't talked to anyone new about eroge and stuff aside from the group so I'm a bit nervous, therefore… can you come with me tomorrow?". Kirino was shifting her shoulders up and down meekly. It was adorable, to be frank.

Usually, about now I'd sigh and be saying stuff like "what if I had plans" or "do you really need me for that?". I was rather listless sometimes, and it probably came off as inconsiderate as usually following that were some usual insults from Kirino. This time around though, I haven't seen Kuroneko and Saori in a while since the welcome party when I moved into that apartment to study. I'm sure they were keeping tracks on me during that time though thanks to Kuroneko's little sister: Hinata.

"Sure, I'll go, I haven't seen those two in a while anyway". With my reply, Kirino beamed up from her embarrassed state to a cheerful one. "As for the new member, don't be nervous, I remember you straight up argued with Kuroneko the first time you met her, so there's no need to be worried, just be yourself." After saying that, I smiled at her and stood up, preparing to leave the room.

As I got outside, I turned back to see Kirino present a large grin before slamming the door in my face. I stared back at where she was standing with utter bafflement. I decided to sigh it off, it'd hurt my brain thinking about it. I entered my room and laid on my bed, processing what had just happened. It was a nice grin.

Kirino:

After I had slammed the door on my big brother, I ran and jumped onto my bed, burying my face into my pillow. I continued to stuff my face into the soft cotton, regretting not asking my brother what I truly wanted to know. I guess I was too scared, not wanting to know the true extent of my brother's answer. Coincidentally, I had another question to ask, and so went with that one to cover up my cowardice.

I quickly flipped and laid down on my back breathing heavily. I put my left forearm on my forehead and stared up at the white ceiling above. Since when did I start to care so much about what my brother says? Even as recently when he agreed to go tomorrow, I was practically jumping for joy. When? When did his simple replies start to make me feel this strongly?

It was because of this recent change in my reactions to my brother that I reacted so strongly when Ayase called me. It was about an hour and a half ago when I was still home alone. I was so relaxed, lounging around watching Meruru on the TV undisturbed. It was all pure bliss and fangirl screeching until my phone rang.

I was surprised to hear Ayase speaking with such a troubled voice. At first, I thought someone had hurt her but then she uttered the words that shattered my heart. It felt like multiple glass shards rained down on me, cutting me up. But it wasn't scary because of the pain, it was scary because I didn't know why I felt so pained.

"Kirino, I...I confessed to your brother". Those words I heard from her mouth were very unexpected. At first, I was just in plain shock, then, as I realized what that had truly meant and that I didn't know that Ayase felt this way towards my brother, I felt sick. I remember immediately hanging up while Ayase was asking to see if I was still there. I had flung my phone onto the couch and sat head in my hands. The lovely Meruru show I was watching had become an annoying sound at the time and it was closed.

I felt horrible at the time, twisting and turning on the couch. I was feeling terrible because I didn't know why I did such a thing. Why did I hang up on Ayase? Why did I find Meruru a nuisance? These thoughts polluted my mind until I heard the front door open.

I quickly pretended to grab a model magazine of the table and laid down on the couch reading it. I quickly glanced over to see that it was, in fact, my brother who came in. It was at that second I really wanted to leap into his chest and embrace him, so that all those negative thoughts would go away.

Ultimately, I had decided to just shrug my desires off and ask him for the same old life counseling, hoping he can solve my issue one way or another. I didn't even have to mutter anything more for things to get better because as soon as he said his magic words, it was like an arrow of happiness that had pierced my heart.

It reminded me of the Kyousuke of old. The enthusiastic big brother who I couldn't keep up with, the big brother who I admired from behind. Thinking about that made me smile uncontrollably, and the fact that I didn't realize I was showing so much happiness troubled me.

Why? Why do you make me so happy now? After pondering this, I got up and left my room, leaving my pillows cluttered across my bed. I opened the door to my brother's room quietly. I didn't have enough patience to knock, I needed answers.

I scanned his room and saw him all curled up on his bed, fast asleep. His gentle snoring and the soft roar of the air conditioning created a peaceful ambiance in his room. An afternoon nap? Perfect timing!

I went closer to the bed to further inspect my brother. He looked very tranquil and defenseless, it was a precious sight to behold. As I leaned closer, a sudden movement of his body almost made my heart spill out into my hands. He had shifted to lay down on his back, his arms and legs spread out in different directions.

I giggled at his new position. He looks like an idiot. If only he was drooling. It would then complete the typical shounen sleeping posture. As I examined his new pose, I couldn't help but notice his collared shirt. It was all wrinkled. Usually, he'd probably take it off and change into more comfortable clothes before taking a nap. But now that he was sleeping in it, I noticed something that made my heart flutter.

His first few buttons were undone, slightly exposing his chest. The wrinkles also defined his torso more evidently. After I noticed this important information, I leaned down to take a closer look, making sure my hair didn't touch him and potentially wake him up. W-wow, he's more defined than I thought. My curiosity piqued. I did not think my brother looked this… fit underneath.

It appears that even though he ceased his track and field activities ages ago, he might have still exercised somewhat. It was at that moment my heart started to pound immensely. Imagining him working out for some reason made my blood pump frantically. My gaze was stuck on his chest, I couldn't break it free!

I started breaking out a sweat. This was very uncalled for. I didn't think I'd be so… mesmerized by his figure. Damn body, why are you acting up like this? It's just his chest! Just this idiot's chest! I ended up staring directly down at him while having internal conflicts in my mind.

Shaking, I lifted my arm and moved it near his torso. What are you doing Kirino? Are you really g-going to touch it? I was panting pretty hard, surprisingly, my frequent gasps for air weren't waking him up. At this point, my hand was right above his chest, and I couldn't take it anymore.

I lowered my hand down and came in contact with his rising chest. It was slightly soft, but firm at the same time, rising up and down in an orderly and calm manner. I was the opposite of that, I was shivering like a madman, still reacting dramatically to the mere fact that I touched his body.

I was breathing heavily as I spread the palm of my hand on his pectoral muscle. I felt his rather toned physique, and I couldn't stop quivering because of it. I never knew my brother was this well built, and that unfamiliarity made me feel weird. Very, very weird.

I reached my existing hand into my blouse and touched my own chest, wet and sticky from the sweat. For a while, I kneeled on the floor beside his bed still touching his chest and my own. I tried to calm down and breathe in unison with my brother as we remained connected.

I leaned forward massively, with our chests in short proximity to each other. I made sure that no other part of my body was touching him as if he woke up, I'd have a lot of explaining to do as I was still shivering and sweating quite a bit. I brought my lips near his ear and softly whispered into it.

"Oh aniki… why do you make me feel like this? Why do you make me feel so… excited?"

AN: I just recently picked up the OreImo series last month and after watching it, I sensed the immense potential it had as I breezed through each episode. Like many others, I enjoyed the ride and was disappointed by the ending, but more importantly, I just simply wanted more of this world, more OreImo in my life. I was inspired by many fanfictions I have read on this site, and since I already had a pre-existing love for writing, it was a matter of time before I started my own fanfiction.

Writing the first chapter has been a blast so far for me, and I can't wait to start writing the next chapters. I aim to make this project a weekly one, however, I am terrible with deadlines, therefore I will attempt to put out new chapters within a week or two of each other. I hope you, the readers, have as much fun reading Serene Days as I have as much fun writing it. I'm sure that with your feedback and reviews, I can try to make this an experience that you and I will both enjoy.
