Sometimes I wish an editor would rise up with some new fresh idea's of writing story's. I know when a title gets popular they write a second volume to please the audience. But why is it with most second volumes the story just get boring and repeating. What would have been interesting was to see these two make life changing decisions. Like emigrating and find a whole new life together. Or pure angst like it would crumble in the end. Or something else what is different then the main gerne story lines. I want to be surprised more. now some stories feel like copy paste once they hit the second volume.
