Gouda-kun's the kind of person who's so absorbed in what he wants to say that it's hard for him to notice the reactions of the person in front of him. He's not blushing, but I think it's probably pretty embarrassing from his point of view so it's understandable that he's thinking really really hard about it.
Except he's causing a huge misunderstanding for Kamine, who's the kind of person that pays too much attention to the people around her in place of too little. Notice, you doofus! Argh!
