I had no problems with the "from here." Might I suggest changing "that restaurant" to "a restaurant" instead? That should fix it.Edited that, all I had to do was cut out 'from here.'
You're right. There's no need to follow it up for the reader.Which is why I felt there wasn't much of a need to follow up. Anything more than that would have just been "here's a bunch of foreshadowing but I'm going to outright tell you in case somehow you don't know."
I was talking about Hisao. Akira just told him that she has a cousin who goes to Yamaku and is even in his year, and Hisao is not the least bit curious who it might be?
He's not even thinking about asking Akira about her. He doesn't react at all and changes the topic, then seems to be way more interested in that other cousin, whom he probably never met before...
