hells yeah thank you so much!!! So I’m assuming this is for the headcanon thing from this post

Lets get started!!

Headcanon A: what I think realistically

I’m just gonna pick random things, I hope you don’t mind. 

First: I think All Might is probably at least aware that he’s not a fantastic teacher, and probably doesn’t favour Deku as much as we see him do in canon, since at some point someone would probably point that out. Like it makes sense story wise that things are Deku-centric, but within the world I don’t think (I hope) it’s not quite as obvious. Also Deku would be in even greater danger if it was that obvious, so yeah, I feel like he’s probably more subtle. 

Second: realistically I think All Might knows that he’s a bit of a heartthrob, and either is Ace and Aro (kinda my personal preferred hc), or else made a decision not to get into relationships.

Headcanon B: what I think is fucking hilarious

First: All Might is not aware that he’s a terrible teacher, or that it’s painfully obvious that he favours Deku over the rest of his students. Why is this funny? Well, in my head, it leads to every goddamn member of the UA Faculty trying to clean up his messes. Like, oh, everyone just sat down for an english exam but got handed maths papers? Goddamn it Toshinori. There’s a clip on local news of All Might having lunch with a high school student? Goddamn it Toshinori.

Second: All Might has no idea that he’s a heartthrob, despite his larger than life screen presence. He’s emphatically not interested in romantic/sexual relationships, and he accidentally leaves a trail of broken hearts wherever he goes because he’s just polite. If you’ve seen Brooklyn 99, I’m thinking of when Terry broke up with someone but it looked like a proposal. All Might helps you carry your shopping the whole way home, tells you he thinks you’re pretty and accomplished, and then literally disappears. There’s a betting pool in the staff room on if/when he’ll actually notice.

C: what is heart-crushing and awful but fun to inflict on friends

Oh hey it’s my favourite!!

First: All Might knows that he’s painfully obvious about favouring Deku, but he is actively terrified Deku is going to get himself killed. All Might deliberately spends as much time with Deku as possible because a) he knows his own life is short and b) after losing Nana, All Might gets severely anxious when he doesn’t have Deku within his line of sight. This gets several orders of magnitude worse when he loses his second form. Kinda ditto re: being a bad teacher. All Might wants to focus on the admin, he really does, but he can’t stop thinking about the horrors and fear that these teenagers are going to be facing, and how he’s actively enabling that, and he veers between wanting them to be prepared and keeping them away from it. He has yet to have the Conversation that all the UA faculty have had about this personal conflict, but Aizawa is ready to sit him down and talk it out soon. 

Second: All Might is aware of the heartthrob thing and severely uncomfortable with it. A) It only adds to the already immense pressure on him to perform/be the symbol of hope. B) He couldn’t keep a partner safe even if he wanted to (Nighteye) C) He’s dying, he doesn’t want to bring anyone else into that. D) Hero society is a whole lot more progressive than it was when Toshi was a teenager, but the idea of a queer-platonic relationship is alien to him. He does want companionship, just not romantic or sexual, and as of right now, he’s resigned to living the rest of his life alone, despite everything he’s done for everyone around him. (Of course, he often forgets the people he already has: Naomasa, Aizawa, etc)

option D: what would never work with canon but the canon is shit so I believe it anyway

All Might is asexual! Well, he is in my head. Also, All Might notices that Todoroki Enji is a flaming douchebag and has a conversation with him and quietly removes him from Shouto’s life and gets Shouto to a safe place. 

Thank you again!!
