It's always the same: whiners crying because a series doesn't meet their expectations, whatever they may be, or hate the story/characters. You don't need 25 chapters to realize that you like a manga or not. If you don't like it, the solution is very simple: stop reading it and read something else.
The author hides information from us and doesn't tell us the secrets!
Tension. Conflict. Plot. You know, those things writers tend to use, especially if you're serializing a story.
Personally, I think Aitsu no Kanojo is another shounen that wants to pass itself off as seinen. But as a quick read between other collections, it's readable.
Thanks for the translation.
