I hate that I love you (Katsuki x fem hero reader)

A new job

Y/N just stood up from bed at around 10 a.m., she was doing hero work until very late, because there was an accident that happened and made her stay at the heroagency she owned. After she made herself something to eat, she hears her phone suddenly ring and sees that Toshinori (All Might) calls her. 

She picks up the phone and says, "Good morning dad", he then answers with "A good morning to you too young Y/N. I have and urgent request for you. As you might have heard,Class 1A, one of the hero courses, has been attacked by villains at the USJ". She then says "Yeah, you've already informed me about that... Uncle got almost killed... and you too weren't in best shape after that...". All Might then says "Ah yes, that's right I forgot I informed you already... Anyway, since that day UAhas been on high alert, but we need some kind of spy, who makes sure, that these students aren't in danger until they graduate and since principal Nezu thought about putting a pro hero into class 1A, I instantly thought about you. You'd be the perfect hero, since you have the same age as the students from this class and you'd be able to go to class, make friends and you can continue to work as a hero while you can have the same experiences as anyone else yourage. Although you'll have to work undercover, and you can't really work foryour hero agency and you can't let anyone know about this job. So what do you say, young Y/N?" 

Y/N just stares at the wall in her kitchen. After about a minute she answers "Y-you mean I have to put up with some stupid teenagers?!" He sighs "You yourself are a teenager, but yes, you have to work with students your age and I also think it'd be a great opportunity for you and make some friends... or even get a boyfriend". She sighs and thinks about whether to do it or not, but since she is in Toshinoris debt, she doesn't decline and finally says "Alright, I'll do it, but I won't make any friends and I surely won't get aboyfriend... When do I have to start playing their bodyguard?" 

He smiles about you agreeing, but she can't see it, because you're only on a voice call "After the weekend. Principal Nezu already informed the government about a pro hero joining Class 1A for safety reasons." Y/N sighs "Alright, then I'll come on Monday to UA and get registered, is that alright?" "Yes, I'll see you on Monday then, I'm sure you'll like it there and Eraserhead will also be your homeroom teacher" He answers. Y/N then says "At least I can annoy him" Y/N giggles.

They then say their goodbyes to each other and Y/N mentally slaps herself for agreeing, not knowing how long she'll have to stay at this hero school and already imagining being tortured with homework by Aizawa.
