What bregoran said.
Easiest way is to go the dom route and don't have sex in the club. If you are on the love routre and go to the club I guess you cannot prevent to have sex and if you skip the club completely (go to sleep) the game suddenly will end at the last act (seems to be a bug for me).
Can somebody explain how to get secret ending please
Dom route and no sex in car after club has not worked for me. I got 4 love in the club and after fighting scene in bathroom decided to go to car and have not triggered the sex scene.
So until episode 7 I had not sex with Nicole
The end path is Dom but after the flashback game goes to present time and immediately "The End" is shown
