The most notable aspect of this manga is the ML Shiota-sensei, who has a very interesting design and personality. Definitely not a guy you'd be seeing too often in a shoujo romance. What's refreshing about this manga is that there's not really a "I'll wait until you graduated high school" thing. The two are eager to kiss a lot. It's an established relationship, I get it, but it's puzzling why these two are even together, because Shiota sensei is shown to have rejected Amai many times before they started dating, and his particular personality makes it even more unlikely that he'd be interested in a high schooler(or any romantic relationship with a woman). So why is he in love with her? And why does she like him? It also doesn't help that Sensei never blushes around her. Oh well. This manga spoils you with precisely seeing that kind of man jealous if his girl gets close to any guys and seeing them kiss a lot.

Also there's an annoying side character who's gay for MC. I'd rather manga like this explore proper friendships with female characters. I guess this is supposed to balance out the lack of drama but eh.
