This is more enjoyable if you just stop comparing it to ReLife. ReLife is it's own thing, and it's over. Blue Hearts is a new story, with new characters. We're still early in the story. I'm not expecting anything crazy to happen until they solve everyone's individual problems (think Little Busters! if you've played/watched it). Maybe Nagi's will be the crazy thing (considering his marks and scars), or maybe it'll be something else, just have to wait and see.
