The story is extremely muddled and all over the place. In my opinion sex can be fine, if the author wants to draw sex that's fine. It's just the author didn't really find any way to naturally include the sex, or make it feel like a proper part of the story.
As "bitfarb" said the sex was probably a way for the main character to release her desires and feelings. Which can work, I just think the author poorly conveyed that and didn't do it well.
However I think that was the biggest problem with the entire story, the sex wasn't so much a problem, as just the entire story not properly conveying any of it's ideas and it didn't properly execute anything. That said the art is well done at the very least.
I think I'd feel better about this one if that "you're a homosexual?" thing didn't happen. The reality of that phrasing makes it seem like lgbt folks are all predators who take advantage of kids who are coming out. If it didn't mention it, I could just apply porn logic.
There is actually a Hentai manga of reina and her boyfriend,the kid has like 10 wtf
it is called "Heart Floating on Air"
Thats actually really annoying to learn. As a oneshot you could interpret this all sorts of ways and even if the sex in the middle's a bit unnecessary at least you could read something potentially hopeful and maybe even cute in the end, or at least find the main character's struggles interesting. With the context it just comes across as some needless angst about a girl who unfortunately has feelings for someone who'd rather have sex with a prepubescent boy than consider a same-sex relationship. Yikes.
Well, Hamao's main product is porn, plot is not their forte, not that it would be the emphasis in porn. This one is a rare Hamao story where the drama is slightly heavier than their usual porn. It's also part of a series of porn stories featuring the girls seen on the cover page (Chuu ni uita mama no Kotoba/Kokoro/Kimochi)(yuri/het/het, respectively), though so far the girl with glasses has not yet appeared in her own story, but it's only a matter of time, I think.
"This is actually connected to 2 other chapters Hamao did years ago: #1 is from COMIC Kairakuten XTC Vol. 6; #2 is from COMIC X-Eros #43. Both are compiled in the tankoubon titled "Candy Drop". They aren't yuri though." - Uploader GO_KENTA
Candy Drop (Hamao) is at the Panda place, in Korean only? 222 pages...
No idea how the one in COMIC Kairakuten XTC Vol. 5 is connected. A black haired guitar playing girl gets caught in the rain and her music-club sempai gets turned on and off they go! In Vietnamese so IDK really :/
The other one is about Reina meeting (tutoring?) her 'boyfriend' and promptly attacking him... then he attacks her, a great deal of sweat is generated. There's a page with Rui and her 2 friends meeting him at the end.
@5Cats: So it's not Rui that turns straight as implied by that other comment but Reina, and it's not any new Hamao tankoubon that I missed :))
I think you were a bit confused, though. The two connected stories to this one are compiled in Candy Drop tankoubon, titled Chuu ni uita mama no Kimochi/Kokoro, featuring the girl with hair ribbon and Rui, first published in Karaikuten XTC vol 6 and X-EROS #43, respectively. The one you described is the single story named Candy Drop, first published in Karaikuten XTC vol 5, also compiled in the same tankoubon, and not related to this series.
Anyway, all these 3 porn works are het, which means not welcomed to be discussed on dynasty here, so let's stop.
