He wasn't exactly ready for that sudden change in this. It was one thing to help someone else, it was another to suddenly being asked if he needed help and there being potential he would have to do more then a bare minimum in regards to a conversation.

"Eh! I t-that is K-konayuki-san, you, you don't have t-to do t-that. You're going t-to see someone important to you and, and..."

And he just buries himself right back into his neck ruff.

"I-i don't want t-to k-keep you from that."

Because important people are special and he doesn't want to keep her from seeing hers just because his family leader was testing him or something. After all, it had to be someone special and important for her to be looking for them all the way out here. Oh no, he may be wrong and was jumping to conclusions and he hope he didn't offend her doing that.

"I-i-i'm sorry if t-that's not right, but it sounds like an important person."
