Eh, lack of proper communication is still their main issue. Yuki still dodges confrontations until she's absolutely forced to, and her insecurities still get the better of her. Naruse's still blunt, jealous, and fails to read the room correctly. His "none of your business" comment was most likely less about wanting to hide or keep Yuki out of it, but more that this issue with Sunohara is not something he should be talking about with others in the first place. They will keep having issues like this in the future, be it with more Hakamada shenanigans or girls that stick to Naruse, unless they learn communicate effectively.
