The solo Reynah's one, the next day of study and diner, on the group chat choose "My last day of freedom... are the chores" you spot Reynah at the bus station. I'm not sure anymore if you have to do more for her CG, because I did it from memory, but it's the way to have it for sure !
For the Cam's one, at the Spring Festival, choose to split up, choose an activity with Cam, and for the second activity choose "You needed a break - to the benches with you."
Hope it's help you !
