I went outside and played with them. At the end you can either invite the boys to join you at the apartment or go back with just Cam and Deja. If you go back with just the two of them, Percy will send the CG in the group chat!
try and do the rainy day on the first day of hang outs. If Cameron is comfortable with the guys, they will typically invite them no matter what. So you could do the rainy day and then just go back without them
