Okay, for sake of ease, for the rest of this conversation, if I say 'sleep with,' it means actually sleeping.

I have slept with Marinette. I have slept with Ten and Rose. There has been random times I have just flopped over somewhere in the box and when I woke up, I had a cuddle buddy. Marinette has offered Chat sleep over privileges.

Literally the only unknown in this equation is Alya. Ten, Rose, and Marinette are all for comfort sleep buddies.
