Author's Note: This is my first written FanFiction ever, so I hope it's okay. I just got the idea of a little nurse Sen and I couldn't keep myself from writting it down ;w;

So first Chapter, Ryuko finds out that she's sick and needs to take the day off, but what happens when a curious Senketsu keeps asking her questions?

4 a.m

(Ryuko's POV)

It was the middle of the night when I woke up unexpectedly. For some reason, I just couldn't get to sleep, or rather, after waking up I found it harder to sleep than usual. It wasn't because Mako and her family were snoring like dragons like every other night. I was used to that by now. It wasn't a weird nightmare either. I was staring up at the ceiling wondering, was it hotter than usual? Or was it just me? Not only did I feel warmer than usual, I also felt really dizzy and before I knew it, I started shivering. My head was killing me, and my stomach wasn't doing any better.

"Oh you've gotta be kidding me…" I muttered quietly. Just perfect. Real FUCKING perfect.

I guess it finally happened, I was getting sick. I didn't think it would happen and thought my immune system was almost invincible, but I guess not. But why now? Why now of all times when I was going to go about another day at that stupid school fighting whatever and whoever that bitch Satsuki Kirryuin threw at me to get even closer to finding out the truth about who killed my father. Why now?! I groaned in pure frustration as I tried to get comfortable again. It wasn't easy, with every move I made sharp pains where coming from all over my body and I was sweating all over the place.

There was no way I was gonna be able to fight like this. As much as I hated to admit it, it had to be done. I had to skip a day. The sooner it was over; the sooner I could get back to fighting again. I just hoped it was one of those 24 hour bugs and it wouldn't last multiple days. That was the last thing I needed. But god, it hurt like hell everywhere, I couldn't even move. But I couldn't wake up Mako or her family, no way. I've burdened them long enough just by taking me in. So I tried to get myself comfortable and ignore the pain, hoping eventually that sleep would take me down again. And hopefully, I'd sleep this off hoping it was just some night issues.

7 a.m.

Before I knew it, it was morning, and I could hear Mako and her family going nuts just like they did every morning. Right now, I wish I had a mute button, none of this was helping me, it was making my head hurt even more. Nothing changed from last night, I felt exactly the same, maybe even worse. I pulled the futon blanket over my face to block out the light of the sun, because that wasn't helping either. I was hoping Mako wouldn't notice that I was still here, I didn't want her to know that I was sick. That didn't last too long though. There she was, barging through the doorway with her loud booming voice.

"Ryuko-chan! Wake up! We're gonna be late! Hurry up, or we might get expelled!" I heard her yell through my eardrums in a panicking tone.

Just once I wish she'd enter the room like a normal person, but that was just how she was. I continued to face away from her and hide under the futon. I didn't want her to see me, because as shitty as I was feeling now, I bet I looked even worse.

"Ryuko-chaaan! It's not like you to oversleep! Come on, we gotta go!" I heard her shout out again.

Oh my god, shut UP. Was all I could think. I couldn't keep up this silent act for much longer or she'd just keep talking. There was no other option, I had to admit it.

"Go on without me Mako, I'm not feeling too good today, so I think I'll take the day off..." I finally said.

I was hoping she wouldn't look too into it. Once again, I was wrong. She instantly stat down beside me placing her hand on my forehead, pulling it away soon afterwards.

"Yeowch! You're as hot as my mom's cooking pot Ryuko-chan!" Mako cried out. "You can't go to school like this! You gotta stay home and rest, or you'll get lots worse!"

I just fucking said that.

Classic Mako. Stating the obvious wasn't too surprising with how much of an airhead she already was. I sighed out heavily, this stupid virus was taking its toll on me and I wouldn't hold out much longer. I had to end this conversation before it was too late.

"Yeah, you'd better go or you'll be late. I'll be fine if I rest some, don't worry…" I said before I was nearly passed out again.

Mako looked at her watch and screamed. Naturally she'd freak out…why wasn't I surprised.

"WAAAH! I'm late I'm laaate!" she yelled out again. "I gotta go! Feel better Ryuko-chan!" Mako dashed out of the room like a crazy person. I couldn't help but laugh at her antics but it wasn't long before that laughter turned into a coughing fit.

"Damn…" I said quietly. "This is gonna be a long day…" I turned around and fell asleep after that.

7:30 a.m

(Senketsu's POV)

I was asleep for longer than I usually was for some strange reason. Nothing seemed wrong, but when I woke up, something wasn't quite right. For one thing, why was I still in the residence of the Mankanshoku's, and why couldn't I read Ryuko's body details? I looked around and realized that I was still hanging in the same place Ryuko usually put me when she wasn't wearing me.

Wait…

Why wasn't she wearing me?Why were we not at Honnouji Academy? Usually when I woke up, I was in the exact same classroom that she was in, listening to Aikuro Mikisugi teaching his usual class while undercover at that school. Sometimes we would pass out because of how boring it was, but that didn't seem to be the case… Why was I still where she left me last night?

Could she have forgotten? Did she leave me behind? No, that's not like her! She needed me to fight against Satsuki Kirryuin! All these thoughts were going through my head, before I heard light groaning coming from below me. I looked down to notice the futon Ryuko usually slept in at night on the floor with somebody in it. It was hard to tell at first, but then I found out there was no doubt. It was Ryuko herself. Why was she still asleep? It wasn't like her to skip a day at Honnouji Academy. I tried to get her attention so I could get some answers.

"Ryuko." I called out.

There was no answer.

"Ryuko!" I called out again with a little more firmness in my tone.

Still, no answer.

Could she not hear me? No, she usually heard me when I called her, though not all of her replies were in a pleasant tone. Could she have been in trouble? Perhaps trapped in a nightmare? I wouldn't be able to tell if her body wasn't in a good state unless she put me on. I decided to move on my own to see if I could wake her up. I put my sleeves to the futon and shook her a little bit.

"Ryuko, wake up." I said.

"Uughh…" I heard her groan. That wasn't what I was expecting. I was thinking she'd yell at me. But something was wrong. When I touched the futon, she felt…warmer? Soon I could hear loud violent coughing coming from the futon, then she turned around. I watched her open her blue eyes slowly looking up at me.

"Senketsu…?" she questioned in a frail tone of voice.

Something wasn't right. When I took a good look at her, she looked absolutely…dreadful. Her hair was an absolute mess, her face was completely flushed, there was sweat sticking her bangs to her forehead, her eyes looked completely out of sorts, she was shivering uncontrollably, and her voice was barley audible. What happened to her? The usual fire of determination in her eyes that she had waking up every day, it was as if it had completely been extinguished. She looked so tired, weak, and even helpless. She looked as if she couldn't get up if she wanted to. She looked worse than she did the first time she lost a battle.

"Ryuko…what has happened to you?" I asked her.

When I asked that question her eyes immediately opened completely and she turned away.

"D-Don't look at me!" she cried out before she started coughing again.

I was even more concerned now. "Are…you feeling alright?"

She groaned in an irritated manner. "What the hell…do you think…"

How was I supposed to know if she didn't put me on? So long as I was off her body, there was no way I could tell if her body was in bad condition. I decided to look into this further, so I tried to move to where Ryuko would be facing forward. If her body was warm when I touched the futon, how did she feel without it? I placed my sleeve to the skin of her face. It was…hot, and drenched in sweat.

"Ryuko, you feel hotter than your blood does whenever you get angry."

"Nice…observation Einstein…" she said in her sarcastic tone then she turned away again.

"Ryuko, what's happened? Why are we here and not at Honnouji Academy?" That was my next question if the ones I was asking were already making her angry.

"I didn't go…" she said quietly.

"Why not?"

This really made things worse. She got angrier, I could tell. She growled and sat up facing me with pure rage in her eyes.

"Why the fuck do you think!? Because I'm SICK, you idiot!" she yelled at me. Then she groaned and fell back to the futon and started coughing and panting holding her head. "…That…was a bad idea…" she said under her heavy breathing.

She was sick? How could that be? She was just fine yesterday. Seeing the state, she was in I could tell she wasn't in the mood to talk about it anymore.

"I…apologize." I said. I didn't want to make things worse for her if she was feeling so bad.

Ryuko groaned again then sighed and calmed down.

"It's fine…I just…hate admitting that…I'm so weak…" she said.

"I see…" I replied.

I had to admit, I was a little curious. I've heard of the condition before, but I wanted to know what the details were. If it was enough to take Ryuko down like this, it was a stronger foe than Satsuki Kirryuin. This was all so new to me. Before I could ask anything more, Ryuko spoke again.

"Look Sen…I feel like shit, I'm tired and I wanna go back to sleep…so could you leave me alone now?" she asked me turning away again.

I decided to listen to her, I didn't want to make Ryuko more uncomfortable than she already seemed to be. I decided to stay put and watch her for a bit while she slept keeping quiet. She sounded miserable, and she looked miserable. Being sick must have not been enjoyable. Before I could think of anything else, I heard footsteps coming from behind the doorway. I quickly jumped back to where I was put so there was be no further suspicions. As I watched what happened next quietly, I wondered to myself.

Could I possibly do anything to help her feel more comfortable while she sat in this dreadful purgatory of being "sick"? I really wanted to help her… I've never seen her look so helpless before…and I didn't want her to go through it all alone.

End of Chapter 1. There are 5 chapters in all and i already finished them lol
