I personally am not against the bad endings, but the way they appeared in the story. The disappointment in me from the 1st ending is exactly this - that while the game was the whole time realistic, logical, and with possible, well explained and well motivated situations, we suddenly received a classic ending in the good NTR traditions - OK, but for me it doesn't fit at all to the course of the events of this story. You see, because of the big cock and the good sex of Luca, a woman - intelligent, respectfull - is turned into a sex slave to the same big cock. Even if we accept that this is possible and Laura suddenly realized that the most important thing in the life is the sex, negating work success, creating family, being in a possition in the society, and so on (which is not logical, but let's accept it is possible) - then why she just didn't broke with Harry in a normal way in the moment she realized that Luca is her man in the life? Such things happen, people realize some thing and sometimes divorsed, it's normal. Doesn't her so much beloved Harry deserved at least this?
I am sorry to say this, but this ending was equal to me, like if it was ending with dragons and orcs - or in other words, 0% realistic. And I liked the game exactly because of this - because the situations were possible, and when you think how a woman cheats while talking on the phone, or while her boyfriend is 1 meter away behind the toilet door, this is exciting, because you make the analog with the RL. If there are some fantastic situations, it is not the same, because little or less you think - OK man, this simply cannot happen, is not realistic.
I think the 1st ending could ended in realistic and motivated way, and still to be bad - like Laura keeps the sexual relation with Luca for a few years, but not destroying her and Harry's life; or if she wants to break their relation at some point, to do it in a normal way.
Here in this ending Luca treats her like a slut and a trash, tells her that he have more whores to fuck, not a hint that he wants to have family with her in any way; and she destroyed her life with Harry - for what exactly, why she will do this? What she will do after that video message? Laura looks like some NPC with the purpose to bring the bad emotions in the end, and doesn't think what will happen with her after that, but she had to bring the bad news to Harry
)) - well ... for me this is not OK.
