Endearing. (Endeavor X Male Reader.)

Best Friend

"Enji Todorki. Why're you always so mad? You always look so grumpy."

The red haired Male turned to face you. Unsurprisingly he looked less than happy.

"If I look grumpy that means I don't like you. So I'd suggest you leave me alone."

You shook your head side to side. Not like you expected this conversation to go any better.

"For a guy who uses flames. You're pretty cold. I'm not here to be your enemy or get in your way. You're very powerful and more smart than you let on. I wanted to be your ally. Maybe a friend?"

He gave you a very questioning look. Before he snickered and turned away. His back facing you now.

"When I'm number 1, I won't need friends or allies. Glad you realize my potential though. That means I'm making myself known. The man who will become the number 1 hero is me, Enji Todoroki. Don't you forget it."

"Yeah yeah. I don't need the monologue. Look an important part of being a hero is being able to work and communicate with other heroes. You'd have a much better chance if you knew any social skills at all. If you'd like I can show you sometime."

Flames reared up around his neck and face. He turned back to you with a bloodshot eye staring directly at you.

"Why are you still here. I told you to leave. Even after all I've said you still wish to befriend me?"

"Well yeah. Thought that was obvious. I don't think you're a bad guy. You just need some people skills. Luckily for you I got those. Whaddya say, partners?"

His flames died down and he turned away once more. Heading down the hall.

"Once we graduate from U.A I begin my mission to become the greatest. You can follow me until then. After that we're no longer 'friends' got it?"

"Hah. I'm sure in the meantime you'll grow to love me! You'll be begging me to join your agency."

"I already regret indulging you as much as I have."

"Well get used to it. Now then let's work on some social interaction. You can't just ignore and monologue to everyone forever...."

Your eyes opened. Another dream about him. Endeavor. The Number 2 hero. He was true to his word. After you both graduated U.A it was impossible to get in touch with him. Even though he was always so focused and angry. You knew deep down he was a good guy who got misguided somewhere along the way. You knew for certain when you'd first seem him. His aura was so calm and alluring. Sure his personality wasn't the same, but he didn't show any sign of malevolence.
Your quirk when activated was just that. To see the auras of people you make eye contact with. Their aura was the closest thing to a soul that anyone could see. It's that gut feeling you get whenever you lay eyes on them the first time. Your quirk definitely wasn't battle effective, and you've known that from a young age. That feeling of powerlessness was bestowed upon you from your parents. Constant abuse and neglect left you with an empty husk of a boy you once knew. When you were 18 they threw you out and U.A was the only hope you'd had all your life. Somewhere away from them, so you could begin to mend what was broken. After taking the entrance exam you made it to U.A and caught wind of some of the highest potential people one of them was an inspiring pro hero by the name of Endeavor, you tried to befriend Endeavor, he looked like he had a lot of anger and malice, and nobody seemed to hang around him or make any kind of contact with him.  
You wanted to show him that it's okay to open up and have friends to lean on.  Break down his shell so he could have an easier time in the future. Arguably a valuable asset to becoming a hero is making faux partnerships when the need arises. Whether that be a large scale villain group or a well planned heist.
Whether he payed you any mind or not is up for debate but regardless you did what you could.
