A/N : Hi! This is my first fanfiction of Nagisa x Kayano! I hope you like it.

They are my favourite OTP in Ansatsu Kyoushitsu!

Hmm, I think this fanfiction will be a mutiple chapters story but this will be slow update because I have many fanfictions and I will update if there's an idea pops up in my head.

But first, let me tell you that english is not my main language, so sorry if there's grammar mistake!

Warning! : This fanfiction contains spoiler from the latest chapters in the manga (from around chapter 128 to 141)

Kayano's POV

"Kayano, do you have a crush on someone here?"

I widened my eyes and coughed repeatedly, then I turned to face Nakamura who was smirking at me.

Actually, the girls said that they would have a girls talk, so all of the girls gathered in front of the toilet. I didn't know why they chosed a toilet as a place to have a conversation... or a discussion about 'love'. Well, Okajima-kun had tried to eavesdrop, but the girls found him and kicked him out of the old school building.

'I don't have a crush on someone here and I don't need one. I have to kill Koro-sensei, just that. I have to take revenge because my sister was killed by him... I don't care about anyone else other than my sister, Yukimura Aguri.'

"Kayano-san?", Kanzaki-san asked, looking confused.

I snapped out of my reverie, then I lifted my head and smiled, scratching my head. "Ah, sorry. I think I don't have a crush on anyone. Hehehe."

"Hmm~ How about Nagisa?", Nakamura asked, teasing me.

I shook my head quickly and denied, "N-No! He is just my friend!"

Nakamura pouted when she heard that.

"But, you always together with Nagisa...", Nakamura said again, still pouting.

"I-I always together with him because he is the first friend I made here!", I exclaimed.

"What are you doing here?"

We turned to see the source of voice, Nagisa, who was staring at us in wonder.

"Nothing!", I exclaimed as I smiled to him. I was an actress after all, so I could change my expressions easily.

"Ooh...", He mumbled. The girls watched him, still waiting for his next words.

"Kayano."

I flinched. 'Did he just... call me?'

I looked up to see his usual smile on his face. Although he looked like a weak guy, I knew that he would be a great assassin... since he could beat Kataoka-sensei. But, deep in my heart, I was still thinking that I was the most strongest student here because I had these tentacles.

"Do you want to go home together with me? I want to buy a pudding for you because I made you drop your pudding yesterday," Nagisa continued.

'... What...? Ah... I think because of that...'

Yesterday, I bought a pudding before the school started. It was my favourite pudding. I was walking happily towards the old school building. But... Nagisa suddenly patted my shoulder and made me surprised. I accidentaly dropped my pudding... to the ground. I was so sad as I knelt down in front of my pudding. I wanted to eat it at the school later... Wait, I didn't want to eat it! The pudding would be sad! I had to keep it in a convenient place! But... It had fallen to the ground... Poor pudding.

Seeing my sad face, Nagisa tried to calm me down. He tried to cheer me up, but I didn't hear his words, just staring at my poor pudding.

Terasaka-kun and other students looked at us. I thought that Terasaka-kun was annoyed when he saw us like that, so he walked over to us and dragged me towards the school.

"You're blocking the way!", he shouted.

"Nooo! My pudding...!", I cried as I looked at my pudding on the ground, but I was dragged until I couldn't see my pudding again. I glanced at Nagisa for a while. He sweatdropped, until Karma-kun greeted him.

That's what happened yesterday.

I gave him a smile, and said, "Okay!"

Saying that, the girls stared at us with a grin on their faces. I sweatdropped as I stood up and followed Nagisa from behind. I turned around to look at them. They waved their hands and gave me thumbs up.

I let out a sigh. Hearing my sigh, Nagisa turned to face me and asked, "What's wrong?"

I shook my head quickly. "Nothing! Ah, I want my favourite pudding yesterday...", I muttered, imagining my favourite pudding in my mind.

Nagisa gave me an awkward smile, rubbing his temples, "Sorry for yesterday. I'm still regretting what I've done."

I closed my eyes and smiled, replying, "It's fine! It's not your fault!"

As we walked down the mountain, I began to look around. There were only two of us. "Uwah... When I think again, we rarely go home together."

Nagisa replied with a nod, then we went silent again.

After walking down the mountain, Nagisa bought a pudding and gave it to me. The same pudding like yesterday. I started eating it happily, making Nagisa smile.

"I want to try eating that pudding too," Nagisa said as he bought the same flavour like mine. We began to walk together to our home.

"Ah, I'm too full," Nagisa mumbled. I looked at his pudding. There was still half of it.

"Eh? Don't waste pudding! If you don't want, I will eat it!", I said.

"Okay. This is for you," Nagisa said as he gave me his pudding. I took his small spoon and started eating it.

Then, I stopped for a moment. 'Eh? Is this... an indirect kiss?!'

My face started burning up and I dropped the spoon unconsciously.

I shook my head. 'No, no, no, no, no-'

"Kayano."

I heard Nagisa's voice, so I turned to see him. He then suddenly licked my cheek softly.

My face became redder when he did that. "N-Nagisa?!"

"Ah, sorry. I licked pudding off of your cheek," Nagisa said with a smile again.

I felt my face became hot. 'N-Nagisa looks different today...'

As I thought that, I had finished eating Nagisa's pudding. We had arrived in front of my home. I said thank you to him and walked up to my home. But, Nagisa suddenly grabbed my wrist. I turned my face to look at him.

That time... Nagisa kissed me. He pressed his lips softly on my lips for a few seconds. He then let go of that kiss and said with a smile, "Kayano-san... I love you."

After saying that, I froze up and stood there in silence. Nagisa waved his hand to me, saying that I could give an answer tomorrow or later.

I watched Nagisa until his figure had disappeared from my eyes. I immediately ran towards my home. I took off my shoes and ran up to my room. I opened the door, then I jumped onto my bed.

'I-I can't believe this. I-I don't know that Nagisa l-loves me,' I thought while pressing my face to my pillow in embarrassment.

Then, I touched my lips softly with my fingers. His lips... was so soft.

'N-Nagisa kissed me... And it's my first kiss...'

My face started burning up again as my cheeks became completely red. I tried to forget what had happened between Nagisa and I. But, I just couldn't.

Trying hard to find out a way to reject him, my memories with Nagisa in Class E started to appear in my head. What I could think all of the time was Nagisa. It was like he had hypnotized me because I couldn't think of anything other than him.

When I tried to think and think again, I suddenly knew that I... loved him too but I always tried to deny it.

"Nagisa...", I muttered as I started to fall asleep.

"Good morning, Kayano," Nagisa greeted me as usual.

I flinched when I heard that. But, I tried acting again as if I didn't know anything about yesterday.

"Morning, Nagisa," I greeted back while giving a smile to him.

"About yesterda-", Nagisa said but he got interrupted by me.

"Oh, thank you for the pudding! It was so delicious! I want to eat it again. Hehe," I replied as I giggled.

Nagisa didn't answer me. He looked confused, but I didn't really care. I was only wearing my usual cheerful face.

We walked together towards our classroom. When we opened the door, we saw Koro-sensei talking to the students with a pink-coloured face. After opening the door, the students turned to look at us. They began to whistle and exclaimed, "That's the new couple in Class E!"

"Eh?", Nagisa and I said in unison.

'Who?'

Yada-san walked towards me and held my hands, then she shook my both hands. "Congrats! I don't know that you and Nagisa are dating!"

A question mark appeared above my head. What? What did she say?

"Hmm, Nagisa. I can't believe you can kissed a girl," Karma-kun said as he walked closer to Nagisa.

Nagisa and I looked confused. Why did he know we have kissed yesterday?!

"Nurufufufu. I followed you yesterday and I wrote what happened to you both in my love agenda. And then, the students tried to read my love agenda without my permission," Koro-sensei explained as he walked closer to us as well.

The other students gave us congratulations. They misunderstood... I wasn't dating with Nagisa... And I couldn't date with him because I just had to concentrate on killing Koro-sensei.

When Kanzaki-san wanted to give congratulations to me, I said, "... I... I DON'T LIKE NAGISA!"

After saying that, Koro-sensei and the other students went silent. I realized what I had said, then I covered my mouth quickly. 'N-No. I-I don't mean it like that... Why did I say that? I can act as always, right?'

No one dare to break this silence. I gritted my teeth, then I began my acting again. "Ahaha... I was just joking! Um, Nagisa, sorry for saying something like that," I said as I turned to look at him. He gave me a slight nod.

I walked to my own seat as I put my schoolbag. The students were still staying in silence. To break this silence, I called Kanzaki-san and Okuda-san, just chatting. After a long time had passed, the students didn't talk about Nagisa and I again, they were talking about another things because they thought the atmosphere would be bad if they talked about us.

I glanced at Nagisa. He was staring at me with a bit shock but still look calm as Karma stood next to him, not saying anything. I instantly looked away from him and started talking with Kanzaki-san and Okuda-san again.

Seeing Nagisa and I, I didn't realize that... Koro-sensei was staring at us, thinking about something.

A/N : What is this? I don't know, this is just a random story. Well, I just want to make a story of Nagisa x Kayano. My favourite pairing here. Then, I have thought 3 arc for this story.

Arc 1 - First Love...?

If she realized that she loved him, but...

Arc 2 - Kiss & Tentacles

If she was controlled by her tentacles, then he...

Arc 3 - High School Students

If they met again as high school students after their graduation and the earth was saved...

I hope you like this story!
