Hm...is there any description of those endings?
Also...when I think a bit about it...perhaps Luca taking Aya and Laura away is not that bad. I remember a phrase that says 'evil begets evil'. When you see Laura and Aya at their worst and get that is what they actually are...
They do deserve Luca. He is as a horrible as them (hate Harry if you want. Luca and those girls are ultimately worse. He is a rapist and Laura + Aya end up complicits in it, there is no redemption for them at my eyes since one basically works to get the other raped) and if Harry thinks a little, he might just give 'thank God' and just try to ensure Luca can't really track him down (because that is the eventual issue, it isn't even the fact those girls are utter disgusting coward pieces of shit, but that Luca for some reason looks to Harry and thinks 'Mommy'. Seriously, he might wanna breastfeed on him or smth or make him take care of him like a mother, since he has such a hate against him).
...and...well, corruption takes a more pure form, like Anakin's corruption. Harry leaves this ready to live on, but not trusting love or women at all, which honestly considering the place and the world...there is no reason for him to actually trust those, finally becoming smart. So he becomes corrupted by contempt and hate, which while might make him bitter...it might allow him to survive and maybe thrive better.
Get out of that without those...toxic pieces of shit, but not without some bitterness (which is expected) that might make him less of a spineless indecisive guy. As for humiliation stuff?
Honestly being tied or having anything with two untrustworthy, backstabbing bitches is far more stupid than anything. Would be fun if Luca or they try to humiliate him with that and he goes.
Harry: Okay, yada, yada, I know, you love his cock, you are predictable and boring at this point, now can you stop being a mindless parroting drone and do your 'job'? I think your 'Master' might have a task more suited to your...actual qualifications. Nonetheless stay away please. You disgust me.
