The way the ecchi scenes are integrated reminds me of early Fate/Grand Order, where every node had to have both plot and a battle, so you'd get the classic Sudden Wyverns.
Like, "Okay, let's explain the plot, some motivations, our future directions and--oh wyverns are are attackings lets go deal with that!--what we're going to do next. But first we're going to have an emotional moment where--wyvern's are attacking, let's do it guys--we address how the fear of battlefield mortality would effect a--Oh, more wyverns, time to kill them all--civilian's mindset when they're thrust into a dangerous situation. Oh, speaking of which, you wouldn't believe what's about to happen.
One thing I think it interesting is how many people (kinda myself included) seem to be a little salty about the way this story is going. I think this explains it super well:
Honestly the appeal at first was "the confident older woman can now make advances on her senpai" but like the MC is also super needy and literally got a job to be able to see her senpai every day at a cafe... like that's not hot confident older woman action anymore...that's just desperate.
Like, the initial premise of "perennial wallflower girl uses the opportunity presented by time travel to steal the heart of her longtime crush," which also contains this side of like, "mysterious confident older woman shows up out of nowhere to save & also top the shit out of me" was sort of this sexy power fantasy with two interesting sides. It's a super compelling dynamic for great junk-food fun that would be perfect for an ecchi manga, and maybe you subtly add some wistful sadness and shots of the older lady (who really doesn't talk much about herself actually, come to think of it) looking out into the distance, uncharacteristically quiet, to give the whole experience some kick. But instead you get... weird obsessive immature adult following you around, and I'm not sure the author intended it to come across that way.
It's like, you're at a new sandwhich shop and you see someone eating this rich, colorful, juicy-looking pastrami and you think, that's about to be me. And you order it, and it smells heavenly, and your mouth is watering--and you take a bite, and there's a piece of clear platic packaging left in the middle of the sandwich, and after you pull it out and keep eating you find it doesn't really taste like anything. That's worse than just ordering a sad-looking sandwich and getting what you expected. Yaknow?
The point is... I get why people are a little peeved. Here's a great example of someone using the juicy, satisfying potential of this set-up well--it's super self-indulgent, and it's great. Also abandoned, so take heed if unfinished stories get to you.
Anyway. Time for lunch. I'm gonna go get a sandwich...
