[Some people would obviously argue the perspective. Plenty of Bakugo's classmates are amazed at his skill in the kitchen despite his yelling there's nothing hard about cooking. (Ignore the fake celebrity identities...) But he wouldn't call himself a "chef" like someone at a top-star restaurant or Lunch Rush in U.A. cafeteria.]

I don't need a damn "lesson", so can it.

[But given how this guy's lifting out of the water like that, Bakugo's lip twitches in irritation. Oncoming lesson. Great. He rests his elbow on the rim of the bath, jaw in his palm.]

If that's all you care about, you wouldn't have flaunted your skills with that bullshit.

[Saying everyone else was beneath him, you don't spout that kind of claim if your attitude towards your skill is as "humble" as Kaito professes it is. Aka: why Bakugo doesn't believe him.

But he takes the food given.]

Don't pretend to have humble satisfaction when you're talking down to others out of pride.

[Granted, not all pride is bad. But not owning up to your own rubs him the wrong way. If Kaito's amazing, he should say it and not back down.]
