Lui sees his old body on the couch to see if Cassie in his old body is unconscious. "She's asleep", said Lui with his girly voice. He started touching all over his new body before stopping and thinking what to do. Lui remembered Davis(This guy is you) and thought he should let you know about this. He left the house leaving Cassie sleeping on the couch. He went to your house which is next to his house and started knocking on the door.
Your POV:
You were playing a game on your PC when you heard a knock on the door. Your family went for a vacation with Lui's parents, and of course, you have to take care of the house. You turn off your PC, went downstairs and peeped through the window to see Cassie outside your door. You were confused at first as why she would knock at your door but you continue to open it anyway. This is when things started to get weird. "Hey, Davis! It's me!", said Cassie. "Huh?", you said. "It's me, Lui. I turn into Cassie". You in a confused state said "How are you Lui? Can you prove it to me?". Cassie thought for a second and said "You remembered the day where you ran away from a cockroach and I saw it?". You were shocked as the only one that saw the incident was Lui. "You really are Lui", you said but still weirded out by the fact that the sexy babysitter who comes for a few weeks is Lui. The problem now is what do you want to do to him.
