Poor Kacchan, i didn't think he had these things into his head
I've had a bit of trouble following his train of thought though:
i got labeled special all of my life for my skills -> deku was a little shit -> suddenly all might appears and start praising Deku for his attitude and not for his Quirk (or lack of) -> i get shown that maybe there is a system that evaluates a person's heart instead of his skills (which means i might not be the best as everyone told me before) -> i get kidnapped for my skills and my bad attitude -> these events sets in motion All Might's fall -> Provisional License Exam comes and once again i got proved that my methods are wrong and Deku receives more praises than ever, he also actually got pretty skilled -> okay i really need to blow my steam off and see if Deku is so special and better than me and maybe he can show me how wrong i was?
Guess i'm pretty close?
