Hi, sorry for the late response, you probably said no when they asked you to be their boyfriend, but it's no problem, you can turn it on using the relationship manager in the character menu.
I actually choose the "yes" choice for both of them and their names weren't in the relationship manager. But I'll try to reset the game and play again to see if it work.
Also is it possible to get 15 points on the mini game with Valerie?
