* I do not own Steven Universe all rights goes to Rebecca Sugar, the only thing that I own in this story is Cairo and Zircon i am also going to but a warning her this story is going to be dark and when i mean dark there's going to death, violence and torture there might be some lemon scenes further on but am not sure yet now without further ado let's get this story started*
Pink Diamond alongside her pearl turn to look at Cairo they noticed he rarely showed his emotions and he was very obedient much more so than other gems that pink and pearl has ever known. Pink then thought maybe she should tried talking and so she walked over to him and said " Hello there Cairo" Cairo looked and quickly stood up "My diamond is something wrong" Pink shook her head and said softly " Cairo may I see your gem" Cairo was confused but decided to leave his shirt up and there place right over his heart was gem so pale and white and it looked like it was glowing. Pink Diamond couldn't help but reach out and was about to touch Cairo gem but he stood up and moved away before saying " My diamond this isn't appropriate behaviour a high-class gem-like yourself shouldn't touch an assassin and protector like me" Upon hearing this Pink Diamond become upset and hugged Cairo " Cairo please stop in my eyes you are my equal, not just weapon"
Pinks pearl looked confused never in her life has she ever seen a Diamond take care of any of her gems like Pink has, Cairo wanted to get away but something about the way Pink was hugging him made him feel safe and sound so he stayed like that and refused to let go that was until Pink Pearl said " my diamond we have arrived at our destination" Pink turned to look at her Pearl before she let go of Cairo and started to walk off her ship, Pearl started to follow her then Cairo. Cairo looked around hoping to see green grass and lakes like when he was kind but all he saw was rocks and hard landscape as he looked around he released he was not on earth instead he was on the moon. As they walked instead the tower he looked to see the memorial of all the diamonds, he stood in front of White Diamonds memorial and touched it with his hand before whispering to himself " I will make you proud mother" Pearl stopped and looked at Cairo in shock when she heard him call White Diamond mother.
Cairo didn't notice Pearl looking at him until he turns away to keep following Pink, at the realization that he was caught calling White Diamond mother he quickly run after Pink and didn't say anything to Pearl. Pink saw Cairo running behind her and chuckled softly as she got ready to take over earth Pearl decided to talk to Cairo as she was curious about why Cairo called White Diamond mother and why no one ever calls him by his gem name. Cairo seemed to noticed that Pearl wanted to talk to him so he walked over to her and said " Hello you must be Pink Pearl" Pearl smiled softly a light blush formed on her face as she answered " Yes I am" Cairo nodded and then asked her " Is there something that you want to know Pearl" Pearl nodded her head and said " Cairo why is it that no one calls you by your gem and why is it that you call White Diamond mother" Cairo smiled and sits down patting an area next to him " It started around 850 years ago I was raised in a small village on earth and I had no parents, all my parents had died during the war on earth and I was left an orphan with nowhere to go than one day I saw a white light and so I followed it and there in front of me was White Diamond ship but of course back then I didn't know what it was" Cairo seem to stop speaking and Pearl turn to look at him with worry.
Cairo smiled softly before counting " White Diamond then come out of the ship and she saw me at first, I thought she was going to kill me but instead she picked me up and asked if I wanted a family and I said yes but I never realised by family she met I was to be trained to be her perfect weapon and son" Pearl upon hearing this felt a sharp pain in her chest and she felt like crying, she was shocked and she tried to tell herself that she wasn't supposed to show her emotions. Cairo seemed to notice and so he reached out his hand to try and comfort her but then stops himself as he remembered what Zircon told him and so he pulled his hand down and walked over to Pink in hopes that she could comfort Pearl.
When Pink heard from Cairo that Pearl seemed upset she quickly got up from sit and started walking over to Pearl after she told Cairo to watch everything for her and make sure that everything is okay. Cairo obeyed and watched everything from the screen and made sure that everything was perfect for his Diamond. As he watched he noticed that Pearl was better and her and Pink were walking back towards him he shot off the screen and bowed "welcome back my Diamond everything is looking good" Pink nodded as he she sits down on her chair.
A couple of years later ( honestly I was too lazy to type the rest of that)
Pink looked at Pearl and sighed before saying to Pearl " please give me a check on the conditions of the kindergartens" Pearl nodded as she went through everything before saying " My Diamond it seems that some gems are coming out from the Prime Kindergarten, this seem to make Pink very excited and she shouted " Pearl" before taking Pearls hand in hers and then she shouted again " Cairo.. Cairo" Cairo heard his name being called and so he made his way up to where a very excited Pink was still holding hands with Pearl.
Cairo was confused but then Pink said "Cairo... Cairo lets go and see the gems" Cairo nodded his head as they walked down to the viewing but for some reason Pink seemed displeased and then she said " let's all go to Prime Kindergarten" Cairo almost choked from shock and was quick to say " No my Diamond we can't" Pink turn to look at Cairo who realised that he had talked back to his Diamond and so he quickly covered his mouth and whispered " forgive me my Diamond I spoke out of line". Pink just smiled and said " Cairo you are just worried about me so it's okay but I promise I will be more careful and besides you will protect me right" Cairo smiled and nodded his head before saying " well you can't possibly go down like that so why don't you change into a Quartz"
Pink smiled with joy before running to hug Cairo to the jealous of Pearl, Cairo chuckled as he noticed Pearl acting jealous. Pink then let him go and changed her form to look like a Quartz Cairo couldn't help but look at how pretty she was and Pearl couldn't help but feel a slight hint of envy she sees the way that Cairo looks at her and to her that was the most painful thing to realise that you love someone but only to have them love someone else. Pearl then felt tears running down her face and she gasps softly whipping them away before anyone could see but, of course, she was wrong because someone did see and that person was none other than Cairo the very gem that she was trying to hide her feelings from. Pink turn to look at Pearl and asked in that angel voice of her's " Pearl are you okay?" Pearl looked up and smiled her broken smile like she always does and says " Yes my Diamond" Pink smiled and run off to the worp pad (( sorry if i spelt it wrong)) as they all hopped on and got worpped to Prime Kindergarten Pink quickly runs to greet the other Quartz.
As they talked to one of the Amethyst leaders told everyone to get a move on even though somewhere waiting for the rest of there group as they left Cairo thought it would be a good idea to go back to the moon and so he took Pink hand and said " My Dia… I mean my Quartz we should head back now" Pink turn to look at Cairo and said " yes of course let's go back" as Cairo took Pink hands Pearl follow and she felt her heartbreak, even more, watching them walk together and seeing Cairo so protective of her it just made Pearl realise that she is nothing more than a Pearl and someone like Cairo who was raised by White Diamond could never be with her even if she wanted them too. As they worpped back to the Moon Pink turn back to normal and went back to her daily business and Cairo disappeared to go and train and leave a sad, heartbroken Pearl to follow Pink back to the monitor room.
