I'll just say this: Although I do know who all of them are, the story seems to focus so much in Emma over all of the other heroines that I'm not really sure why are them even here anymore. I mean, one thing would be if she had a dedicate arc, something that is really common in harem stories, but Emma simply is the one that recibes the most attention all of the time, while the others seems to be there just so this can be called a harem (yeah, he does this kind of things with them too, but is like the MC is only romantically interested on Emma).
For the novel readers: Are things always like this?? Or is this way only here in the manga??
