WARNING MINOR NSFW REVIEW!!!!! WARNING MINOR SPOILERS AHEAD!!!!!! Don't know why this is classified as "erotica", this is literally a hentai, from what I know (don't know about MAL's guidelines between Erotica, Ecchi & Hentai). ECCHI - shows oppai, chikubi and other stuff but doesn't out show genitals, it can be implied or like sexually suggestive, but it won't show any genitals and won't have s*x, if they do, they don't show it and just implied it afterwards, if a girl is naked in ecchi, the triangle down there is just blank or most of the time have aconvenient censoring.
EROTICA - from what I know, this also considered "smut" in the manga tags, in smut or "erotica", they did the job (have s*x), they show the characters doing it but still isn't showing any genitals, it's like the bottom part is always cut out from the panel.
HENTAI - we all know what this is, full blown s*x, showing genitals (a HENTAI can also have a good story, sometimes even better than the ECCHI mangas).

See here, the characters shown having s*x, which automatically cross-out the ECCHI, now we see here a censored genitals of both genders, EROTICA shouldn't be the tag here, this should be a HENTAI. Now there's also another basis for EROTICA vs HENTAI, the POV or the targeted demographics, I could see it if this has over the top romance & heavy drama, I wouldn't argue about it being an EROTICA because I think that's one of the proper ways to identify an EROTICA vs HENTAI manga, but it isn't, most of the stories are RomComs, in HENTAI, there's also RomComs, meaning, if this were read by boys, it would be "HENTAI", you can't argue the amount of s*x shown between this manga and other H manga as they're almost the same, most of the manga is about the s*x scenes, there's also some different fetish and play here like the 3rd story has BJ, fingering and stuff, collection of different stories also exist in H mangas, I really think this should be tagged as HENTAI, kept rambling about the tag, enough about that, let's review it.

If you're reading the synopsis, it's a collection of different types of stories, most of the stories are your typical RomComs, Light romance with little to no drama, some key stories I'd like to focus on my reviews are the following:
3rd story is pedophilia, i know that most of the people says that age is just numbers and not just in "being young" or motivational speechs, the term can also be used in love, but come on, even the manga shows the adult guy's thinking at first, he being a 9th grade and the girl being a 1st grader, 8 years age gap, there's a big problem if the older person (regardless of gender) pursues the younger person, but if the younger person pursues the older person, as an older person, it is your job to tell the younger person that it is pedophilia in the older person's POV.
5th story, again pedophilia but this time it is in reverse, the girl is older and the guy is younger, but that's not the only problem, no no no, this is one of the story about a simp, the older girl basically got cheated by her long distance BF, she used the young boy as rebound, saying "I didn't notice", come on you already know that, you let him on a "bro zone" so that you can try to catch bigger fish (she tried like her now ex-bf) and wants the younger boy as the safety net, so the problem here pedo + simp rebound.

The art style is on the average side of things for me, not too hot, unlike some of the ero-mangakas that I follow and average for your typical manga when then it's not a s*x scene.
