Then I met you- Part 2
Summery: your life has never been easy and then you met him
Pairing: Kelly Severide x Reader / Matt Casey & Reader
Matt was once again trying to convince you to go to Molly with him. You hadn’t spent much time with the guys after work, and people were starting to wonder why.
It was just so hard to pretend not to know Matt at work and you didn’t want to do the same in your free time.
“I’m just saying, it’s been a month. Everyone can see you are made for the job, why can’t we just tell the truth? So you can come to Molly with me and everyone is happy”- he said
“I just need more time. I don’t want to lie either Matt, but every time it doesn’t go well. Remember Gabby?”- you knew it was a touchy subject but you wanted to bring the point home.
“She liked you”- you couldn’t convince him otherwise, but you knew she didn’t.
“Sure”- you rolled your eyes- “listen I’m gonna go and have a shower. You don’t have to stay at home with me Matt, please go to Molly. Spend some time with your friends.”
“They’re your friends too”
You wanted it to be true but you knew people at 51 hadn’t a clear idea of you yet. The jury was still out and you knew it was mostly your own fault. You needed time to open up, to feel comfortable with new people and not everyone liked to wait.
“No they are not Matt”
“They could be”- he wanted you to become part of the family so much.
“Go to Molly and have fun”- you screamed while going to the bathroom to start your much needed shower

You got out of the shower, put a towel on and went out of the bathroom.
You noticed the light of the kitchen was still on, Matt had decided to stay in after all. That guy... always sacrificing himself for others, it was clear he wanted to go to Molly but he didn’t want to leave you alone.
You had never been lucky but you sure lucked out with Matt.
“Hey Matt you didn’t have to stay”- you said while entering the kitchen, still in your towel- “I told you, I’m gonna be f_”- you stopped suddenly.
Sure Matt was in the kitchen but he wasn’t alone, Sylvie was there with him and evidently she didn’t know you were there. Of course she didn’t, why would she.

“Sylvie I...”- she was so nice and you could see the sadness in her eyes and you knew it was your fault.
‘You destroy everything you touch. He’s gonna leave you, why wouldn’t he.’
You could hear your ex’s voice in your head and you were so taken by your thoughts you almost didn’t notice Sylvie leaving
“I’m sorry, I didn’t mean to bother you guys” she said while practically flying the house
“Wait” said Matt but she was already gone.
You were in silent for a while waiting for Matt to get mad at you but he didn’t... of course he didn’t
“I’m so sorry Matt. I didn’t know she was here”
“Hey you didn’t do anything wrong ok? I invited her in without warning you”- he was smiling but you knew you had to fix it.
“I’ll talk to her, I’ll explain everything ok?”- you’ll fix it... for him
“I thought you weren’t ready”- he didn’t understand why you didn’t want people to know. It wasn’t because he didn’t want to, he just couldn’t. It had never been him receiving the ‘look’ once knowing about you, about your past. He was the good guy in the story, you on the other hand...
“You were right, I have to do this sooner or later, better be sooner right?”- and if everything went to shit at least you hadn’t been there too long to form proper bonds.
He hugged you because he knew you so well; he knew telling people the truth meant talking, at least in part, about your past. And you hated your past, but you had to... for Matt

The next day at work talking to Sylvie proved to be more difficult than you thought.
Between the calls (during which it wasn’t professional to talk) and her clear avoidance was not happening.
So once you were back from another call you blocked her before she could leave
“We need to talk”- you said blocking her path- “please”
Matt had always said your puppy eyes were dangerous and you had never believed him, but you knew you had to try with everything you got, so you gave her your puppy eyes.
“There is nothing to talk about”
“Yes there is. Listen it’s not what you think. I swear, I...”- she stopped you before you could continue
“You don’t have to explain me anything. It’s not my business”- she was calm but you knew better. She was hurt, if because she liked Matt or because you didn’t open up to her, you didn’t know. But the hurt in her voice was very much clear.
“Sylvie Matt and I...”
“I don’t care if you sleep with Matt”- she didn’t scream but she was loud and you both hadn’t noticed the crowd forming
“You slept with Y/N”- someone behind you said
You turned over and basically all 51 was there, you looked at Sylvie again and you could see she was sorry. She hadn’t noticed them either
You could tell it had been Severide who had talked.
“I thought you had a thing for...” - Kelly started again but stopped before saying too much, but he was looking at Brett so it didn’t take a genius to fill the gap
“We didn’t sleep together”- Matt said while looking between Kelly and Brett
“It’s not my business but don’t lie straight to my face at least. She was half naked in your house Matt”- well the cat was out of the bag. And everyone was looking at you
You had to say something
“I live there too”- way to go Y/n, you told yourself.
“You guys live together?”- Herman said- “how long have you been together?”
“Oh my god we’re not together”- you tried again. When you promised Matt to fix it you didn’t think you would have to talk in front of all the guys.
“So you live together, sleep together but are not a couple”- Stella summed up
“I’M HIS SISTER”- you screamed and yup... everyone was looking at you like you were crazy.
You turned around and went to the bathroom ready to throw up. Damn it you hated confrontations and now, you didn’t have to explain everything only to Sylvie, but to everyone at 51.
Damn it.

It’s been so long, I know and I’m so sorry. Sadly I can’t promise a schedule but I’m gonna try to post more frequently. Don’t give up on me please.

Then I Met you- Part 3
Pairing: Kelly Severide x Reader / Matt Casey & Reader (siblings)
Warnings: angsts, age difference
Note: In this fic Matt and Kelly are 38, so Matt was 21 became a firefighter (2003). Matt and reader are 11 years apart, so the reader is 27. So be aware of the age difference, if it bothers you don’t read it 😊

You were sitting on the bathroom floor trying to regain your breath. When you had decided to talk to Brett, you didn’t think you would end up having to explain yourself to everyone. But the deed was done and you didn’t have any other choice... this didn’t mean you weren’t going to postpone it as long as you could though.
You were so deep in thoughts you almost didn’t hear someone entering the bathroom. So when you heard someone clearing their throat, you jumped a little. Two feet were near you and, when you looked up, you saw Severide.
He was leaning against the bathroom wall and he was looking at you like you look at a scared animal.

“Hey”- he said softly - “are you ok?” - he continued when you didn’t say anything
“Sure, I just know everyone is out there hating me because I lied to them and I, honestly, don’t know how to explain everything... it’s just, my life has always been complicated... let’s leave it at that. And now that I finally feel like things are changing for the best... ehmmm”- you groaned
“No one hates you and you don’t own anyone anything”
“Why, when you need a call, there isn’t one?”- you rhetorically asked
“Hey don’t jinx it. Beside are you seriously hoping for someone to get hurt”- he was smirking
“Thank you, now I’m feeling even worse. Beside I was hoping on a little scratch; you know people call for anything”
“Listen”- he said squatting down in order to be at your eyes level - “You have to deal with the guys out there sooner or later, you have just to go out there and if you don’t want to explain the situation you don’t have to. Matt has already pointed that out. It’s up to you”
You looked at him, his eyes were even more beautiful this close. You felt suddenly calm while looking at him and it kinda felt weird, because it usually happened with Matt.
Matt had always been able to calm you down with a simple look and you didn’t know how to feel knowing there was someone else who suddenly could do the same.
“Yeah it’s time”- all at once speaking with the other was easier than being alone with Kelly. You barely knew him and you refused to let this feeling overwhelmed you. Beside you had promised yourself you were done with man since apparently you weren’t good at choosing them.

You and Kelly went to the common area and everyone looked at you in silence.
“You ok?”- Matt asked you once he came closer
“Yeah. It was bound to happen, right?”- you whispered while he hugged you. He squeezed you as tight as he could without taking your breath away, knowing it would calm you down.
“Ok... well, as you guys heard I’m Matt’s sister”- you said while looking at the 51.
Sylvie was looking at you apologetically and you smiled at her to let her know you weren’t mad. It wasn’t her fault, it was yours firstly for keeping it a secret and secondly because it was you that had started the conversation where anyone could hear you.
“How come we never met you before”- asked Herman
“And why didn’t you tell us when you started working here”- asked Ritter. He was the one you had bonded the most beside Sylvie
“As I was telling them, you dont have to feel obligated to answer their questions”- Matt said
“I know, but I think they deserve to know the truth. Ok well I should probably start with saying that Matt is my half brother, not that change anything for me, but yeah... we have the same father but different mothers. We didn’t know about each other for years, when my mom had me, his parents were still together so I grew up mostly with my mom and I have her surname. When I was 10 my mom died so I was put in the system and my social worker searched for relatives that could take me in. That’s when I found out about Matt and Christie, we had a couple of meetings but Matt had just finished the academy so he hadn’t a stable income and home and in the end I was put in a foster home”
“Why didn’t you go with Christie, she was older and had a home and worked already, right?”- Herman asked
“Christie and I... we don’t really get along. It’s a complicated situation, let’s say we had different relationships with our father. She has always put him on a pedestal and my presence was unsettling for her. The social worker asked her but she didn’t feel like taking me in would be the best thing for the both of us”- you shrugged a little.
You were uncomfortable with talking about Christie, saying that you two didn’t get along was an euphemism. She basically preferred to behave like you didn’t exist. You knew that finding out about you had been difficult for her, she had only known a version of her father, one that was very different from the version you and Matt had known. But even though you understood how difficult it had been for her, you still felt deeply hurt about her behavior; you had been 10, you had just lost the only person that had ever loved you in your life, so it hadn’t been easy to feel rejected by her. You had felt so alone back then.
You took a deep breath and stopped thinking about Christie.
“Matt and I kept in touch while I was with my foster family but when I was 12 a family out of state decided to adopt me, so we kinda lost truck of each other for some time”- you said
“When did you guys get in touch again”- Sylvie asked
“I was 19 and I came looking for him. I was trouble as a kid, I’m not gonna lie. So when I said to my adoptive family I wanted to leave they weren’t so sad about it”- you laughed bitterly
“But how come we didnt know about you before? I mean it’s been seven or eight years since you connected again right?”- Cruz asked
“It’s more complicated than that... I haven’t always been with Matt since I was 19, I stayed for a while and then I... I left again... listen I’m sorry... I’m sorry I didn’t tell you sooner. It’s just I’m not that proud of my past and I just wanted to start fresh, but I knew that telling you guys I was Matt’s sister would bring a lot of questions. And Matt is a saint so he went along with it; so I’m sorry but I’m not ready to tell you the rest, I hope it’s ok”
“Of course it’s ok kiddo, just know we are a family and whenever you are ready, if you’ll ever be, we’ll be here”- Herman said before coming to hug you
“Thank you”
“But... for the love of God, stop avoiding the Molly’s”- he added and you laugh
“I promise”
You looked at Matt and he was smiling proudly at you.
You knew you had still a long way to go, there were still a lot of things about your past you were too ashamed to talk about, but it was a start.
Ambulance 61 man down
“You asked for it”- said Severide and you smiled at him before following Brett
“Listen I’m sorry I got you in this situation. I didn’t know everyone was there”- Sylvie said once in the ambo
“It’s not your fault. We’re good right?”- you asked
“We’ve always been ok”- she said
“Yeah sure... beside when you taught I was sleeping with Matt and wanted to kill me”- you laughed
“Oh shut up!”- she said blushing
You smiled looking out of the window ready for the call.
Ok... sorry if something doesn’t add up with the timeline of the show but it’s not that easy 😂
