Yeah that was definitely Nasa he's already confirmed to exist in this universe and I doubt there'd be many other characters who would just casually solve giant technological problems like that in this universe
That sounds like Nasa but Why newly wed? IF the sempai was one of the girls that Nasa was teaching currently at that all girls school, would this mean this is series is set in the future and they've been married for sometime now.
nah, this is set around the same time as TNK, since Himeka and MC saw the Nasa Tsukasa park kissing scene.... and Nasa did do a lot of freelance work before and after marriage, senpai's company is just one of them...
BTW, where did you get that senpai was a student at the high school? I don't remember seeing that anywhere...
