I predict that good ending will be the one where Harry, understanding Laura but not trusting her, will finally take the matter in his hands like a man instead of relying on her or her mother. That being said, I don't know if he'll choose to stay with Laura, it could as well end up with getting rid of Luca and then breaking up with Laura because of her not wanting to share the burden with Harry and him going his own way to find a better and more trusting/trustworthy woman.
Hero ending 2 though... Not a fan of how things are proceeding so far. Really feels like characters just becoming different people just for the sake of the plot, especially Laura with her flipping the switch in her head from "OMIGAWD I LUV HARRY SO MUCH" to "I'M SO CRAZY, I LOVE DICK, MY MOTHER IS A WHORE, LET'S BURN IT ALL DOWN". However, if someone is into hardcore degeneration, mindbreak and total misery, he must be in a fucking heaven right now lol, because shit's about to go really dark.
