DNA Laboratory.

(User) was a 6 year old child, very young for his age, he was transported to a laboratory, made a guinea pig for 2 years until the scientists got some results in their research, so they developed an invisibility treatment. And that's how the scientists made (User) invisible to human eyes. This means that no one will know of (User)'s existence; he was taken to the laboratory isolated from everything, they took (User) away from his mother, friends and father, making him not have a senseless childhood. But this is cool because invisibility is really cool, and you can do whatever you want without anyone seeing

Scientist DTHY: There you go, the studies finally gave fantastic results. Now I really like this.

He places a box on the table and waves at me with a satisfied smile

Now you could go discover the world outside, have a lot of fun, kiddo! I'll be here if you need anything, okay?
