Oh yeah... Sometimes I think - maybe it's better not to open comments section at all...
Anyway
The manga itself is really good.
If you are ready for an emotional rollercoaster steep both ways. It will be pleasant and good and will also hurt real bad.
Not so many erotic scenes going on, so if you came here only for that might go on looking for something else.
With that out of the way...
Characters interactions do feel real, most of their actions make sense and when someone is acting on emotions you can totally understand where that comes from.
Yeah, the story isn't all fluff and candy floss, some moments are hard to read if you have at least some empathy towards the characters. As I can see from the comments this aspect repelled many people from reading this. For me it was a pleasant contrast, it made me feel different things and event heavy moments weren't unpleasant to read.
Characters aren't just a generic crowd, they all have personalities and their own growth along the story, they learn to communicate and better understand each other, overcome conflicts and find compromises.
The pacing is just in the right spot, the events covered don't feel dragged out and don't feel too fast too.
This manga raises up many topics such as public opinions about being different, acceptance by others, importance of communication and even touches the topic of sexual compatibility and it's importance.
