Thank you!
It sounds like that is probably Rhea's alternate path. The way you treat Joy impacts that route. So whatever you did, do the opposite to unlock that scene. Cleo's scenes are from her room event. After a certain point in the story, she should make you an offer to play dice for stakes in your room. It's different from a normal Dice game.
It sounds like you just need to progress the storyline for everyone, and there should be more content for both of them. Here's a sneak peek.
