I don't know if I missed something but I found these endings:
- final with Emma shared... only with Martin? there is no ending shared with Matthew (even if there was a threesome with him too?)
- cuckold ending only with Matthew... and not with Martin (is it possible that it isn't there?)
- good ending with Emma remaining faithful
- bad ending with Emma cheating, both with Martin and Matthew
I honestly don't know if I missed anything
PS.
Personally, I would have added a variant to the unfaithful wife plot, including anticipating the ending in one or more circumstances with Patrick's outburst of jealousy. I mean, in that path we have an MC who is jealous of his beautiful wife, but at the same time too dumb not to immediately notice what is happening: anyone would understand it (even without using Emma's POV).
In short, from his point of view, Patrick notices:
- Emma is more and more excited and "for fun" she would like to go further
- From Martin's cloud he understands that she has started lying to him and hiding things from him, such as photo shoots, bathing naked in the jacuzzi with other people and the fact that she passed herself off as Martin's "girlfriend"
- From the same cloud as Martin, she sees the photos he secretly took and understands that he has a weakness for Emma, yet remains almost indifferent.
- Likewise he does nothing (he will not investigate later either) when he sees through the webcam that Martin is about to take advantage of Emma and realizes that she is awake and aware.
Then he goes back home:
- He always wakes up alone in bed at night
- He hears Emma moaning in the shower but instead of coming in to join her as he wants, he knocks on the door, but Emma suspiciously won't let him in... and Martin is strangely nowhere to be found (make sure he was in his room, no?)
- Martin and Emma are often close, complicit, flirting in front of her eyes (in the corridor, on the dance floor, during photo shoots, during the move)... not to mention Patrick's return from the move where he finds them in the bedroom, with her under the covers (TOO suspicious), and then has the brilliant idea of leaving them alone there again so as not to notice what's happening.
- In the end it's clear what Emma is up to behind the set of the latest photo shoot, when Martin mysteriously disappeared too... as at the same time it is clear that at least she was naked doing something with Matthew on the last night: her clothes are in the bedroom and she comes back wrapped only in a towel claiming that she was in the pool (but since she hadn't dived in she was dry, and the costume that she obviously didn't have?)
On that path I did everything I could to make Patrick open his eyes sooner, unfortunately he will never do it, except at the end when it will be too late

Again, it would have been interesting to see (as happens in some other games) an ending, perhaps brought forward to the middle of the game.
