Izuku has AFO but repressed it for years. Now that he has OFA he's starting to lose control.

All quirks want to be used and all quirk come with urges. If Izuku hadn't noticed that he had AFO, he still got to deal with the urges and contained them through quirk analysis and sheer enthusiasm when it comes to hero. Unfortunately, getting his first quirk breaks the fragile balance he used to have.

He doesn't realize what it means at first but the urge is here. He wants more quirks. He wants to see what makes them tick. He wants to use them. But since he doesn't realize that it's his quirk manifesting, he internalizes the hell out of it.

Except that internalizing AFO means that he accidentally but fortunately unlocks the quirks inside OFA. He unlocks Blackwhip while fighting Overhaul. After that, it's a mad search for more quirks, to know what they do, all in all, he is far more invested and frantic in the discovery of the OFA quirks.

"Could you please calm down with all your new quirks?" *hungry stare at whoever is talking's quirk* "Never mind!"

The urges get worse when he is stressed or upset.

He doesn't explain anything to his class. They just guess and one day, Uraraka is "Hey, I can't give you my quirk but you seem stressed so you can play with it a little. If you want."

And yes, he would love to play with the quirk. Thank you, Uraraka. You're a real friend.

The rest of the class joins in and they find out that it's not that Izuku needs to steal the quirks and hold them forever but his brain needs enrichment and if he goes a month without playing with a new quirk, he starts to get stir crazy.

So not only does everyone learns not to interrupt his quirk ramble (he needs it! It's good for his brain!) but every time he looks upset or stressed, he must fend a hoard of classmates who are "Hey, you can hold my quirk!/You want quirk?/ Here, take a little quirk, as a treat."

"I am not upset! I was thinking about what to eat for lunch! I swear!" "How about some hardening quirk for lunch?" "Kirishima, you know I don't actually eat quirks. T_T"

Needless to say, he will absolutely take quirks from villains. And his whole class can tell because he is hella relaxed for two months when he takes one.
