What is this about good and Hero endings? i thought there wouldn't be a clear happy end here? Or maybe it will be happy from Harry's POV only? I love those kind of endings.
Having endings dubbed the "Good" or "Hero" endings doesn't necessarily mean it'll be a clear happy ending by any means. Unless HC wants to go back and retcon a choice into the very beginning of the game, Laura is going to get involved with Luca and so a good or happy ending would have to somehow come to terms with that fact, but I imagine some people wouldn't consider that a clear happy ending as they would be looking for a "evaded Luca's plotting and escaped without cheating" sort of ending for them to consider it a clear happy ending.
Just guessing from the labeling though, I suspect the hero ending might be Laura sacrificing her relationship with Harry. She plays Luca's game and then the truth comes out at some point, she could eventually get away from Luca but maybe not, Harry leaves her and thus she becomes the hero who sacrifices herself and her relationship with the man she loves in order to save him. Alternatively, Harry could find out and somehow do something to save Laura from Luca. I guess we'll have to wait and see! As far as good ending, it might be the same but Harry staying with her after realizing she did it to protect him and that she's a victim as much as he is. The two of them might somehow try to get revenge on Luca, perhaps by finding a way to get him arrested. Afterwards they live happily ever after.
In neither scenario though would I say that it's a clear happy ending. There's would still be lots of pain, guilt, and trauma after it was all over and done with. A happy ending is kind of relative to which character's perspective we would see it from, but since Harry is the MC, I think looking for fairy tail endings where they all lived happily ever after is a going to be an unrealistic hope in this story.
