Monologue, monologue and more monologue.
Another manga that has its drama 100% explained by monologues in the first chapters, nothing is left for the reader to interpret; it's amazing the condescension that Japanese authors have with their readers. The concept of subtext seems to be something from another planet for many mangas. All internal conflicts are EXPLAINED in the FIRST TWO volumes. These monologues come out of nowhere and deliver everything important about the characters.
The characters and their dynamics are quite complex, so it's a shame that the author chose to do it this way, instead of slowly exploring, unfolding the psyche of the characters over the course of the plot, at least the first three volumes, which are not there very engaging.
Usually, works that are character driven don't have a very exciting plot, but this is rewarded by their characters that make us turn the gears in our heads and think: "What the fuck is going on?" Or "hmm... interesting", but when explaining everything at the beginning, the author unfortunately didn't allow that to happen, so it's very likely that many readers will stop reading because they don't feel anything that makes them scratch their heads in curiosities and go back to fully understand the work.
But despite this long dissertation, don't think that this manga is bad, it isn't and doesn't even come close to being, especially from volume 4 onwards, which is where the plot starts to get interesting. The problem is that i wam just a little frustrated with the narrative approach, which stole the work's chance to reach the value that everyone says it has (I don't think the high score is very deserved). And although the monologue problem reoccurs in volume 6, it's not as bad as it was at the beginning.
My other and only problem would be the meh art.
