Almond

Almond centers around Yunjae- a boy who was born with underdeveloped amygdala which makes him unable to identify and express feelings like people would normally do. His mother constantly teaches him how to manipulate his emotions and deal with social interactions

A Quote: 

“From what I understood, love was an extreme idea. A word that seemed to force something undefinable into the prison of letters. But the word was used so easily, so often. People spoke of love so casually, just to mean the slightest pleasure or thanks.”
― Won-pyung Sohn, Almond
