Author's notes: Hey all, it's my very first story. So I hope it's not too bad and you'll enjoy reading it. I apologize for eventual language mistakes, but English isn't my maternal language. Thank you to #MyTwinFrenchie for her encouragement and support.

I just want to precise I'm not pro-Dawson or pro-Casey, but a pro-Dawsey and this story is just my ideas of the events, nothing more.

Story: Gabriela Dawson and Matthew Casey are together for over a year, but since Gabby started her candidacy on her fiancé's truck, their relationship began to be in a shaky state. They decided to take a break and eventually found again a complicit relationship. But everything changes with the arrival of a new Chief as well as a new Squad's member. Are they finally going to realize that they cannot live without each other?

GABBY'S POV

I am actually painting in the firehouse's garage while the lieutenants are cleaning the windows after Casey was lacking respect to the new Chief. I have to admit I am proud of him, always standing for his guys, whatever it takes... and also for the people he loves, always.

That's when my worst enemy made his appearance. Tommy Welch is the replacement Squad's member of House 51 and I didn't take his arrival on a very good eye in view of our common past.

I was surprised that he congratulates me on my save during our last call. He never wanted a female firefighter in his truck; he was a total jerk to me, even heading to the headquarters to refuse taking me as a candidate. All of this because I am a woman.

Because of him, I started my candidacy on truck 81; because of him I'm working under my fiancé and because of him my relationship with Matt started to degrade, even leading us to take a break.

Seeing me reluctant and suspicious towards him at first, Welch starts talking and apologizes to me: "I'm sorry that I didn't take you at your word the other day about you and Casey splitting up. I believe it now."

Deep down I don't understand why he apologizes; it's not his kind... I'm confused, but it's nothing compared with what's going to follow : "But you should let your lieutenant know that he can't be making out with a Chief's ex on the apparatus floor or Pridgen will destroy him."

He stares at me during a moment before leaving. And I stand here, shocked by the bomb Welch just left.

I raise the head to Matt and fix him in the eyes. His look tells me that he figured it out what happened during my conversation with Welch. It's always been a question of looks between us, we were always capable of understanding each other with a look, even before being in a relationship; and this one leaves me no doubt: Welch was right.

I feel the anger and the frustration raising me. I shake the head and toss my brush away before leaving the garage in fury.

Numerous thoughts invade me, while I feel tears flowing on my face: How he can do this to me? Yes, I'm the one who asked for a little break, but it's a fucking break not a total split, right?! I thought he agreed with that after our dinner the other night...

MATT'S POV

Chief Pridgen totally pissed me off talking to Otis like crap. He showed his ability for a long time. Make mistakes sometimes is just human.

When the chief has Severide and me cleaning the windows of the firehouse for supposed "insubordination", I look in and see Gabby below painting. Welch approaches her, and consider our history I feel a little worry for her, but most of all I can't trust Welch.

My look of worry become a look of fear; fear that Welch will give away my little secret. Welch saw me earlier at the firehouse with Beth, the chief's ex. I was telling her that's it wasn't what I wanted. I know what I want and it's definitely not having fun with some random girl meet in a bar. It's not me so I told her our little affair has to stop, but even though she kissed me one more time at the moment I less expected and of course the moment Welch chose to make an appearance.

When I see Gabby look at me, I know Welch told her about this little fling. And she looks disappointed, stunned at first. But I know her, she's furious. And my fears are confirmed when she left the garage in total anger.

I watch her leave; hurt and I feel like an idiot being the cause of her pain. Again.

I can't control my annoyance anymore and I punch the wall. Severide look at me confused "It becomes a habit... What's wrong with you?"

I look at him, not sure how to tell him how I really feel. In a few hours my whole life exploded: a new chief against me, the love of my life who hates me... I need to fix it; I need to talk to Gabby, to explain myself.

Under the surprised eyes of Severide, I come down from the ladder, well decided to find Gabby and sort things out with her. We both have our wrongs in our relationship, but I'm the one who threw away everything following Severide advices and going back to the market, while the last weeks we got closer again, we could discuss without yelling at each other, and just spent quality time together. I need to make up to her, I need to have her in my life, and I can't live without her. She's the one, and for years now.

I run inside the house looking for Gabby, everyone look at me, including the Chief but I don't care... All I have on my mind is Gabby. She's not in the common room, she's not in the lockers, and she's not in her bunk... So I continue to the bathroom and I heard someone sobbing from the last shower.

"Gabby..." I call her softly, pulling the curtain. Watching her like that, squatted in the shower, her legs to her chest, her eyes red from crying hysterically and her smooth make-up literally break my heart.

My love who's always so strong and stubborn is broken because of me.
