lmao why are most of you guys here complaining about how much bad the story is when the whole point with this series is a set-up for this kind of stuff this pretty clear for the first few chapters, the story doesn't need to be meaningful to the point it will change your world view. This manga is basically fun on it's own it's like to-love ru but with girls.
Yes it doesn't need to be meaningful, but story should have some sort of development, like character development, story flow etc, but after 10 chapters and 1 extra, the story and character still seems to be in the start.
It's OK if author just want to go for ecchi-chi route, but in other manga similar to this at least at one point the pervert MC would act seriously and the outcome really helps the heroine or make her develops a feeling towards MC, that's when we readers thinks that "ah it can't be helped if she falls in love if MC was so kind and help her this much", this is just an example but at least author make the story flow and character reasonable and also make some development in the character, not just acting pervert and horny only in every chapter.
But until now just feel like when MC act horny, senpai will also somehow act horny, so you just feel weird because the flow just suddenly happens, but I guess this is what you said the story has no point at all, if author just make a one-shot Hentai of this story in Yuri NTR Anthology I guess it wouldn't have so much people discuss and argue to find some righteous in this manga.
