I feel that laura "master plan" will be similar to the ex wife in Illicit love. Laura will try to separate aya from harry, as she bangs lucas crying and wondering why harry doesn't love her anymore.
Maybe, but I don't see maya being involved unless luca decide to "pick" her again from the streets and that feels a tall order on my opinion. To my knowledge (I stop playing the game) maya isn't living in the same town as luca, harry and laura (correct me if I'm wrong). unlike laura mom, which it does have the possibility after this ending, but who knows after this ending the blood is stronger on this one (if you catch my drift) and laura won't let go of her mom that easily (I could be wrong). Regarding aya, that'll be the fun case, she is a low key nut case with her potential personality disorder, and possibly cut lucas throat or bite lucas dick during fun time. Laura.... we already see her, so I don't know what to tell you.
I do want to see an ending like a doujin I read last year were the male mc have a mansion. He lives with 4 females and gets cucked by two guys that arrived to help with the house by the suggestion of one of the girls. To cut it, to the ending, the girls went to the beach and when they came back they saw the mc naked as he laugh hysterically and burns the mansion (don't know what happened to the two guys but I assumed they went with the girls and have sex at the beach).
