So this is going to be a review of the manga so far (58 chapters), so my opinions/criticisms of this manga can easily change by the time this manga ends.
Story: Oh man, if you're a dude who loves a good romance with some great ecchi, this manga will most likely hook you in INSTANTLY. The first chapter really slaps the reader in the face with some things you wouldn't really expect from a typical school, romance, comedy manga. However, if you're not hooked by the first chapter, I think you should probably refrain from reading this manga cuz the first chapter pretty much sets
up the premise of this manga. I really don't wanna spoil anything, so for the story, I'd say just read the first chapter and decide from there. I give the story a 8 thus far because the story does indeed get really deep into the real world, but because of the harem vibes and what not, the story could turn some people off. Also, as a slight warning, there are SOME incest vibes in this manga, however, the characters are not blood related whatsoever.
Art: Holy balls. Go to that first chapter and tell me with a straight face that the art isn't EXTRAORDINARY. At least compared to 99% of romance, school mangas out there. The chapters don't stay in color throughout the manga like the first chapter, obviously, but nonetheless the art is amazing and consistent..there have been no occurrences where I had trouble noticing what's going on.
Characters: I can say that all the characters are likeable to an extent. They all have faults that can make you hate or love them. The MC can be really loveable at times, acting like a gentlemen and what not while other times he can act like Makoto from School days..seriously. Personally I love Hina-senpai, the MC's teacher, while many hate her because of reasons that I don't want to spoil...and I really dislike a character named Rui simply because I think she's super controlling, but others call her best girl. It really all comes down to preference with this most of these characters. I can't really say much without spoiling, I apologize.
Enjoyment: So far, I have really, REALLY enjoyed reading this manga to the point where I marathoned all the chapters in one sitting and couldn't even go to sleep last night because of it. However, people can have different opinions. I love this manga because I simply have a guilty pleasure of reading School romance love triangles with ecchi vibes and sweet romantic moments. Others might find this kind of thing weird. But I LOVE it. If you're familiar with Seo's works (like Suzuka, Kimi no iru machi and Fuuka) you'll probably come to enjoy this manga a lot!
Overall: It really all comes down to what you think after the first chapter cuz that sets the mood and story for this manga. If you don't like the first chapter, chances are you most likely will not like the rest of the manga. Right now, I'm REALLY enjoying this manga and I hope the story stays how it currently is, however, I have a slight feeling that shit might hit the fan soon which just might change my enjoyment level drastically lower if that happens LOL.
