Euphoria: mannaka gou kan jigoku shidou hen - серия 2 (Эйфория: Упивающиеся страстью. Разверзшийся ад.)

-Kanae was never "real". At least not in the sense of being a childhood friend. Kanae was the Doctor in the real world who was running "The Paradise." The Kanae during the game was fake and never really existed.
-Nemu wasn't actually evil. Nemu had met Keiske as a kid and then for some reason she ended up being key to the success of "The Paradise" and was put into a tube.
-Keiske was going to die and Nemu begged Kanae to save him. Kanae saved him under the agreement that Nemu would do whatever she wanted (I believe this meant Nemu would go into the tube and run the paradise?). Also there was some sort of bet (This part I'm really fuzzy on) between Kanae and Nemu. Nemu had to make Keiske kill her in the simulation as part of the bet, which is why Nemu was such a raging b****, even though she loved Keiske.
-Keiske was put through the game countless times. And every time he would have his memory wiped and put straight back into it.
-Nemu's goal was to enter the Paradise with Keiske. Keiske told Nemu he wanted to live on the real world with her, but she didn't want to do that. Keiske told her he was going to the real world and she told him goodbye (I'm guessing she assumed they would never see each other again?)
-Kanae was killed in the real world during the process of transferring Nemu to a different company (due to Kanae being a spy and betraying her company).
-Nemu's memory was wiped by Kanae it seems, because she doesn't remember Keiske at all. Plus she appears to have barely aged at all.
