You have a half-sister and you decide to do a test when she is only 6 years old. You educate him in philosophy, politics, psychology and many other fields, and now he is 18 years old and has a potentially manipulative character.

This character suddenly came to my mind.

If you want this type of weird characters, let me know in the comments section.

I won't make excuses about it being in the "+18" category and don't ask questions that don't have answers, please.
