I think I found a bug when you're in Chuck's route, when you go to his house and Jer drops you off and after you tell him you'll be his boyfriend the next days the situation repeats itself again for a few days before the game gets stuck in weekend mode even in the working days (Monday to Friday) Perhaps you could look into that?
Sorry, forgot to put the thank you credits signaling the end of Chuck's route for now, since he only has 4 work days as of right now, so it would repeat when choosing to help him out. Also at the end is correct with showing the weekend options, since you aren't going into work. Don't worry, in the next build I'll have more days for him and make it apparent that you are taking the day off.
