Hikari offering to "give them space" only for Yuu to deny her inference...that's only gonna make it harder for you down the line, Yuu.
But, Haru managed a customer interaction. And Granny is absolutely correct - it might seem like "something anyone should be able to do", but the reality is that's not the case, nor should it be minimized as such. This series does have some focus on the concept of "weaknesses, strengths, and overcoming the former and building up the latter", so having it play out in little ways like that throughout the story and its characters is great to see.
Thanks for your continued work on this series.
