Mentioning Ayumi is fine and not really a spoiler 
But hmm, I don’t think they mentioned anywhere that Ayumi specifically talks about her day to Yuu as he listens to her. But that’s really beside the point, so I won’t prod further.
But yes, it is definitely an interesting situation he has. He doesn’t seem to care much for other people that aren’t himself… Except for Ayumi, it seems. Do they have some backstory between them that explains this? I guess we won’t find out until two weeks~
