4 weeks later

''Hey, Casey right?''

Surprised Matt turned around as he saw one of his old teachers. He tried to remember who it was and what he was teaching but he couldn't. But he was sure the man had been teacher here when he was still a student here.

''Yeah.'' Matt turned around, shook the man's hand.

''What are you doing here?'' The man said surprised and now Matt remembered he was the man that had taught them about dangerous situations.

''I w-work here now.'' Matt answered as he leaned on his cane as his right leg was starting to shake. The man frowned. ''I am sorry to hear you had to stop working, I heard you made it to lieutenant. You were always so eager to learn.''

''Well, b-bad things happen sometime.'' Matt relativilized and the man tapped him on the shoulder as he walked on. Matt looked around, searching for the office where he had to report, but he couldn't remember where it was, looking around he could hardly picture himself being here again after ten years.

Several students passed him and he looked after them. Some reminded him of himself and finally he just started walking down the hallway, hoping he was going in the right direction. At the end he finally saw the office and he entered. Last week he had been here once to talk about when he was starting and he would start when the new semester started in two weeks, but the woman that he had met last week had called if he could come today.

''Matt, thank you for coming.''

Matt sat down. ''No problem.''

''The woman whom usually visits school to represent the academy and the CFD is sick and there is a visit to an elementary school planned today. Do you think you could maybe do it?''

Matt walked through the doorway of the classroom, looking for a chair that was still free and he sighed when only two were free on the first row between two other boys in the first row. Awkward he moved through the row and the chairs and tables, accidentally bumping his bag into one of the girls behind him and he sat down with a deep sigh. The guy on his left looked at him for a second. Matt grabbed his bag, throwing his phone and keys in. Looking at the key from his dad he remembered he should go there today as it was his dad's birthday. He would be the only one, which made him doubt if he should go.

The teacher entered and greeted them, starting a speech of how proud they should be to be here and that they were brave when the door opened again. A tall guy ran inside, panting.

''Who are you?'' The teacher said, annoyed by the guy running in late.

''Andrew Darden.'' The guy climbed over the table next to Matt and sat down, sighing.

Matt looked aside, just as the rest of the class did and Andy looked around back at them with a funny smile.

''I had hoped most of you had passed this stage of infantilism.'' The teacher sighed and everybody looked back. Matt got his books ready on dangerous situations and got his pens. One was immediately grabbed away by Andy as he wrote his name on his books and Matt looked aside with big eyes.

''Andy.'' The guy introduced himself.

''Matt.'' Matt whispered back, immediately looking up as the teacher hit his hand against the blackboard.

''Darden and blue eyes, be quiet!''

In the lunch break Matt walked to a free chair somewhere when Andy joined him again.

''Hey, Matt! I sit okay if I join you?''

Matt nodded and they sat down at a table that was free. He didn't know what to think about Andy, but it was good to make at least 1 friend at his first day.

''So. Why did you join?'' Andy started off and Matt shrugged.

''I just think this is what I want and what I should do.'' Mat tried to contain his smile as he saw his sisters note in his lunchbag, wishing him a good first day with the drawing of a fire truck.

''Cool.'' Andy mumbled, his mouth stuffed with sandwich. ''My dad was a firefighter.''

''Oh.''

''It sucked, he was just never home. That is why I don't want a family. Never.'' Andy shook his head and Matt looked away. As if his dad ever had been home. He had been away for months several times and when he had bene home, it wasn't any better.

''How about you?'' Andy mumbled.

''I guess not.'' Matt said, not knowing what to say. He knew he wanted a family, but he never wanted a 9-5 job.

In the bus Matt looked around, nervous. He really liked children, but it made him nervous he would have to stand in front of a whole class of them. The woman had given him some cards and papers about what to say, but he still had no idea. His phone was shaking in his pocket and he took it right before stepping off the bus.

''Hey, Gabby told me you had to go to work today, I am off so I could pick you up, we could get something to eat.''

''I promised Gabby to eat at home, she had some n-new recipe she wanted to try.'' Matt excused to Kelly.

''Cool, but I am still going to pick you up and bring you home, so where are you heading?''

Matt explained which elementary school he was going and finally got out of the bus as the bus arrived there and he got out. A woman was waiting for him at the door of the school.

''Matthew Casey.'' He introduced himself.

''Lily Mason, I teach the sixth grade, they have been very excited for today.''

''So am I, t-this is the first time I do this.'' He said as they walked inside.

''Not that there is any problem, but they told be there was a woman that teaches at the academy.''

''I w-was a firefighter, so I think I am able to tell a lot as well.'' He said as they reached the class and Matt's stomach almost turned around. he had never been very good at public speaking and when he entered the class and the children all looked at him he felt even more nervous.

''So guys, this is Matthew Casey and he was a firefighter, that is cool, huh?'' Lily Mason helped him a she didn't know what to say.

immediately a hand was raised by a girl; ''My uncle his a firefighter too. His name is Tom Johnson do you know him mr Casey?''

''No, unfortunately I don't.'' Casey smiled back. ''But I am sure he is very b-brave.''

''Last year, the firefighters came to help when my grandpa was in a car crash!''

''They also saved our neighbours house!''

''Maybe mr Casey can tell something about his job before you ask him everything.'' Lily said as she handed him a chair and he sat down. Telling about the stories the children came closer and closer and he enjoyed how anxious they were to hear about her stories. It reminded him to telling stories and reading to Griffin and Ben.

While telling about the life in the station he was surprised to see somebody looking at him from the hallway through the window and he was surprised to see Kelly standing there.

''You see that man standing there, that is my f-friend, Kelly Severide. He works on s-squad and probably has even more s-stories than me.''

He waved Kelly to come inside and after a moment of hesitation Kelly walked inside.

The childer looked at Kelly with big eyes as he stood beside Matt, a little uncomfortable because of all the attention.

''The guys from s-squad save people in very dangerous situations.''

''But not just the guys from squad, the men from truck save people too. Matt saved a baby in the last rescue from a burning building.''

The bell suddenly rang and while Matt expected them to jump up and run away as he did when he was still a kid and in school, but instead they all kept sitting there.

''Kids, lunch break. Please thank mr Casey and mr Severide for their visit. Maybe they will answer your questions during break.'' Both men nodded but the girl with the firefighter uncle raised her hand again.

''But we want to hear more from Matt and Kelly.''

''Yes.'' The rest of the class joined her and it was adorable for both men to see the kids to desperate for them to tell more.

Matt sighed relieved as he and Kelly finally sat down in the car after 3 more hours of questions and stories.

''It wasn't that bad.'' Kelly laughed; ''Right?''

''No, that is why I am r-relieved. I had expected to be w-worse, or them to laugh because I s-stutter.''

''You are a hero to those kids. They don't care.'' Kelly smiled at him. They drove back to the academy where Matt reported at the woman again, telling how it went.

''I actually really liked d-doing this.'' Matt said as he gave her the papers.

''Hmmm. See you again in two weeks.'' She just mumbled, not looking up.

After that they drank one at molly's and Kelly brought him home.

''Hey professor Casey.'' Gabriela smiled as he entered and she climbed of the couch. She took the bag and kissed him as he entered.

''Enough of this.'' He smiled as he loosened the tie and threw it on the chair of the dinner table.

''How was your shift?'' He asked as they sat down at the dinner table. It felt so family like it almost made him laugh, as he knew neither of them had every expected this to happen.

''It was good...this is so weird.'' SHe said than shaking her head.

''I know, almost n-nine to five.'' Matt sighed gloomy, realizing this was he had always feared. He had never expected himself with a 9-5 job. He knew that eventually, one of them had to move to another firehouse because they knew working together would never work out because they would see each other all the time. It was not that he was really jealous at her, but he envied her, that she could go to the firehouse and he was stuck in a job he would never have done.

''We will also s-see each other less as our w-work times differ.'' Matt sighed. He started to like the idea of teaching less and less. Today was fun, but as soon as he had to work at the academy full time, he knew he would hate it. Besides, what would he even have to teach, they hadn't even told him.

''Well, I am sure it will work out, we live together so when we are both free we will see each other.

Although he really liked it he doubted if this was going to last.

NOTE: Uh oh? Can Matt ever really get used to a 9-5 job? Will it tear his relationship apart or will he try to fight his way back to 51?
