Injuries and kisses
I'm just gonna use he and him pronouns right now cause I'm still a learning writer and they, their pronouns I forget so quickly. Also reading the manga and watching the anime are so hard to understand when it comes to gender terms cause the manga says "he" and what I remember the anime episodes said "she" I had to actually look up the gems gender and they lack any human characteristics of a female or male body part meaning they are sexless. This book might be filled boy x boy, girl x girl, girl x boy (not my best work actually) don't go writing comments about complaining or hate I'll just delete it. Also this may  contain spoliers from the manga. 

You're human but you have the ability to live as long as the gems. You can die from harm but not age in this. Also this is before the chapters of what happened in the ocean. NOW ONTO OUR ONESHOT THAT WAS REQUESTED!

A human child with (H/c) hair was sitting in a chair while Kongo-sensei was teaching them about the history of earth and all the needed info.

Unknown to the small human the other gems were watching and acting like fangirls and a few who acted like they didn't care but were curious of her. (We know who they are).

Suddenly the human heard some giggling after sensei just explained he was going to teach some different subjects. Curious the human looks to where they heard the sound.

She saw multiple people with strange colored hair. The human didn't have hair like them. The human wasn't even like them she was actually a girl and was extremely "fragile" meaning a lot of things were different.

The others immediately ran off after sensei looked over. The human girl didn't understand what had happened and didn't help but to notice someone with delicate bluish green hair and eyes. The human would later learn that this gems name was phosphophyllite.

That certain gem had taken a liking to the new human and had grown closer without even thinking or noticing it. The human had (h/c) hair that was beautiful in phosphophyllite's own words. She also had bright (e/c) eyes that were like a gem. One thing Phos didn't understand was why the human wasn't allowed to fight with other gems.

Was the human girl not strong enough to fight? [Phos don't understand how humans work] After a while the human girls body had started to grow differently she had gotten as tall as phos but just shorter by two inches.

The humans chest had gotten bigger? Phos didn't know what those weird things were on the humans chest but decided against touching or asking when Kongo-sensai was nearby. After a few more years the human acted weird on certain times like once a month during an entire week sometimes. [Girls we all know this pain and we fucking hate this time]

Now whenever Phos asked (Y/n) she would just bring up another topic like nothing happened. Phos even asked Kongo-sensai about it but he wouldn't answer it completely only saying it was personal business. Currently the human was carrying a couple of books. Alex had asked her to do this.

(Y/n)'s POV
I wonder what Alex wanted with these books but maybe it was for moon people? I didn't realize I had gotten sucked into a trance. When all of a sudden I didn't feel the ground I quickly looked down to see I had slipped on a step.

CRASH!

Next thing I knew was I had let out a small scream and now I'm under a pile of books wincing.

"O-ow" I weakly muttered as I tried crawling out unharmed only to get someone crashing onto me. I left out a louder yelp at the sudden heavy weight and was picked up by someone right after it.

It was Phosphophyllite who had picked me up. He seemed extremely worried. I wonder why he was so worried until I felt something warm flow down my face. I reached a hand up and saw some blood. I suddenly felt Phos running down the hall holding me bridle style. I immediately became embarrassed because of this I didn't expect the clumsiest person I know to be able to pick me up without and run while carrying me. (This is fanfiction just pretend you're either lighter or close to being around the 1 scale of hardness weight)

He had started to freak out on the way and started whining loudly to Rutile while I sat in his arms confused and slightly relaxed at his touch. Rutile was trying to calm Phos down by saying I'm ok but Phos wasn't gonna 'no' as his answer. He started to running around with his hands on his hair while saying multiple things like "Y/N's broken!" "What am I gonna do!?" "What if she has memory loss!?" 

Rutile just watched amused and sighs "Phos calm down Y/N isn't broken and she won't have memory loss from that" Rutile grabbed a cotton ball and some wax putting it my forehead and glaring at Phos to calm down. Phos eventually calmed down after Rutile had put that cotton ball on my forehead which stopped the bleeding. Then pulled it off and put it in a wooden bowl beside the table.

Phos had calmed down and had basically tackled me to the ground right after I made a huge pitched squeak. I looked up at Phos eyes and noticed out position. Phos had his hands on both sides of my head while I had my hands on my chest. Phos seemed to notice and got nervous.

I couldn't help but giggle at Phos actions he's adorable I just couldn't it was basically impossible. He heard my laughter and basically became embarrassed. I cupped my hands on his cheeks while he froze up and I pulled him close to my face. Kissing his nose while smiling.

He sat there confused for a second seeming confused. Then he tries to kiss my cheek but slipped and kissed my lips. We both froze up right at that only to hear some of the gems yelling at Phos.

"PHOS WHAT ARE YOU DOING TO Y/N!?"

Phos squeaks and got up running away from Jade who was yelling at him. While Dia pets my h/c hair smiling.

"You care about Phos don't you?" Dia asked while smiling

"M-maybe I do Dia but it seems he feels the same otherwise he wouldn't have tried kissing my cheek" I answered Dia's question quietly.

Yeah I love Phos and I know he loves me back now.

Was that ok? I hope this was ok and I really hope you enjoyed it! I'm not the best at writing but I did the request.
