Of course there is a better way. Hell, there are multiple routs, that could led to better story. But we're talking about manga artists. They are not writers. They (most of the time) don't have any decent background in writing/creating a story. Their narrative is very, very crude, almost child like (in many cases just child like), so it's only given, that they won't be able to create something deep. Or even "not shallow" at this point. Especially nowadays, where literally anyone can become "wannabe" manga artist, by posting their work on sites like pivix, from where bigger publishers will fish out titles, that have gained popularity. Not that long ago that wasn't a thing.
The moment I understood that, everything became somehow easier.
