Worldbuilding sucks tho. It's too unbelievable for me to suspend my disbelief. No country on Earth would agree to such
an immoral thing as committing genocide to "failed" teenagers and washing their memories clean. It's simply too inhumane that it's guaranteed to never happen in a futuristic world.
Aside from that and the romance which sucks, this is pretty good so be the judge yourself.
Nah, certains countries have been doing this "culling" stuffs for a while and still going, just not on only children but ethnic minorities.
