Hmmm, I would say that, at a point, this event will be shown again but from Shota's perspective. And the game will have a pretty fun turn.
Now, however I'm gonna say it : If it wasn't for Nagai and Sensei's Age gap and social standing (student x teacher is bad, nuff said), I think they would be a great match. I mean, they got pretty compatible personalities.
And for Shota, their story is pretty much resumed in this manga.
Yes, it's bad, just plain ephebophilia if I'm correct.
Those age gap relation ships feel like fantasy fulfilment like one of those "My Middle-School Teacher was so hot, I wish I had a romance with her" or something of the same caliber.
But I stopped caring about the whole Age gap thing anymore because it's just a fictional story and I know there won't be any... Ahem moments. At the end of the day, I read both "Game Over" and "14-Sai no Koi" for the wholesome relations between the different lovers of these series, even if I don't approve of some morally speaking.
