Overwatch - Second Generation [Male!reader insert]

Chapter 1

Well, I guess this'll be my first day.  This school looks like some sort of military base - well, for now at least.  Apparently there's four different departments so this would have to be one of them-
BANG!
What was that? It seemed to come from the door on my right. I open the door very slightly to see a peculiar-looking man with his hair on fire... holding explosives?! God this school is messed up.

—LOOKING FOR DORMS—
The receptionist said I was in the dorm at the end of this corridor. I knock on the door and there's no response. I knock again, a little harder this time. I can hear someone fidgeting with some keys and he finally manages to open the door.
"Oh hey, you must be the new guy! What's your name?"
"Um, I'm Y/N. Y/N L/N."
"Nice to meet you Y/N! I'm Dacio. Dacio Correia dos Santos."
He then proceeds to let me into the dorm. There I meet two boys called Liam and Gabriel. They're fairly nice but Gabriel prefers to keep himself to himself. I understand though. I was a bit like that at my old school.
"Alright, so this is where you'll be staying!" Dacio says. "You're sharing a bedroom with me."
I'm fairly happy about that. I feel like I'll be able to be really good friends with this guy.

—LUNCHTIME—
The receptionist told me to come back to her at lunch so that's where I am now. She gives me my timetable and explains how it works. I'm a bit confused but from what I can see, there's a variety of lessons over two weeks. She says we're on A-week Wednesday. Apparently I have computer class after lunch break. I don't know where it is, but maybe I could ask Dacio-
I leave the reception building and Dacio was waiting for me this entire time?! Wow, I gained a friend quickly huh?
"Hey Dacio, do you know where computer class is?" I ask.
"Oh, I have that too!" he says, comparing our timetables. They were completely identical...
RING!
"Just follow me okay?" he says, grabbing my hand and going at, like, 100mph with his ROLLER SKATES. I want some now.
We walk into computer class together. That teacher... Isn't that Sombra? That girl that's really good with hacking? The others look kind of scared of her. I'm completely fine with her though.

We're about halfway through class. Liam, who was sat next to Dacio, has his hands trembling as he types. I figure that he's probably scared of Sombra. Gabriel, on the other hand, looks happy to be in the class. Sombra is instructing the class, when mid-sentence, Liam faints. Is he really that scared?
Dacio and I volunteer to take him to the infirmary and Sombra lets us go. I'm trying to keep Liam upright and Dacio is leading me to the school's infirmary. We arrive.

Who is that nurse?

Sorry it's short. I'm just making this at school so I have limited time. Sorry about that :p
