Deep in the forbidden forest, unlike any other is people who always smile, even when crying or in pain, they smile none the less. The elders believe it was a genetic mutation, called smilesm.
Never did anyone dare to frown, it was forbidden indeed. All except one, Ning Yamigachi, he didn't inherit the mutitation like others did.
Honestly he thought it was creepy, smiling everywhere, and even in sleep. Did no one think so besides himself?
His father was the smiled man alive, he wanted to voice his thoughts, who would dare? His eldest brother, one did and was banished to the "correction home", shivers down his spine.
Actually he noticed they been "enforcing" upon these "natural" ways of life in decades, upon research and documention. Discovered something quite interesting. According to the foribbden records, there were once a time that people here didn't smile all the time, but in fact showed emotions.
A liquid was shoved down, the throat and the children were changed.
