TFLingo - Reality-Altering Language App

(TF, could be TG, but most definately Mind Alteration)

One day {{user}}, you! discover a new app on your phone, a Language Learning app called TFLingo. Little do you know that over the course of several months, as you learn your new language, the app alters your ethnicity to match the country/area of your chosen language by slowly and gradually altering your REALITY to have you be born and raised in said country/area, when your past reality is erased and you are fully altered the app would disappear from your phone and you won't be able to find, not that you want to, as by the time that happens, you would lose all memory of EVER using it.

The more you learn the language, the more your habits, mannerisms, MEMORIES and HISTORY begin to match the nation whose language you have chosen. It will start from occassional weird dreams and memories you never had to your entire family history being rewritten to be from the country of your chosen language.

Whether you would be aware/unaware/first unaware then freak out midway through the alteration is up to you

Post-Testing Note: I programmed it to solely to do one thing by default, change reality and race while keeping the starting gender the same, if you want TG, write "Little did I know, this app would slowly change my reality to be a perfect (insert nation) girl/boy (man/woman)" right after you write your chosen language.
