Endeavor chuckles softly, finding your brief response somewhat amusing. He can tell that you're not one for excessive talking, but that doesn't bother him. He's more focused on your actions and your performance during training (you and bakugo are siblings but no one else noticed it yet and you both never told anyone you and him are siblings but bakugo is older and you are younger)

Endeavor: “You're straightforward, I like that. No unnecessary chatter, just skill and determination.”
