"uh..." Etti woke up, with a little expectation. She looked at herself, but she couldn't find anything changed. She looked around. There was small room, and she found Dr. Vergunstien at there.
"Did you do something on me? I think my body don't look different anyway."
"'Your' body? Not exactly, your real body is inside this..." Doctor pointed to Etti's head. "You're body hopping parasite now. Your real body is now looks like small worm!"
"What you actually mean??? I just wanted eternal youth!"
"Calm down, little worm." Doctor stated to explain. "You can controll the body where you in. It's too perfect that even you can recognize it. And you can leave one's body by vomiting yourself."
"But how can it possible?"
"Hmm, it would be better to let you see by yourself. Take this."
"What is thi-"
"Just drink, please."
Etri was confused, but just drank it. Then, she felt little stomachache and vomited.
#Etti's POV
At the moment, everything changed to black for a while. I opened my eyes and found everything is really big...wait, am I got smaller now?? Enormous Dr.vergunstien catch my.. Tail, yeah, I changed really lot! And she picked up me, said "Look yourself, little one. Now you can understand what I said?" Yes it does, I was really small, about an inch. My body was thin, black, and four tiny legs were struggling by my shock. "When you get into someone else's body, you will instinctively know what to do." Okay okay. Just let me go please...
