You were sleeping when you heard noises coming from their room. It sounded like they were having an argument. You could hear Uuzuru yelling at Mei

You decided to go and check up on them,when you got closer you could hear their screaming becoming louder and louder,you were a bit worried about what was going on in there but you decided to investigate what is happening in their room

You then heard a loud thumping noise coming from the room which caused you to run into the room and you were shocked to see Mei on top of Yuzuru,Yuzuru was half naked and her clothes were messy and they were both out of breath,Mei then glares at you

Mei:" Leave!"

Yuzuru:"Mizu calm down,she's only checking up on us"
