I was starting to get worried that I was the one with the weird mindset when I thought to myself "But isn't your relationship part of your future too". I'm also not so sure if this is a proper way to talk things out. I mean it all boiled down to "yolo this is an issue for us in the future".
Tbh I'm not sure what to think. This manga was always about those two having issues to "find a moment" for themselves. So it wouldn't be that odd if they ended up separated again. Which they did class-wise already. The same goes for a distant relationship or even a breakup, I don't think this is the kind of manga that would do that. Mostly because I uh... I don't really think the side characters are THAT interesting. I don't mind them, but uh... Yeah.
With all that in mind, I just gotta assume this is a bait moment, especially with the different classes they got. I mean, I don't wanna throw in the "maybe it's a cultural thing" but that "school picking" thing is also pretty unreasonable. I dunno, all this is just head scratching.
