The main character slaps herself in the face
There are some scenes of implied violence, the strongest of which feature some blood spurting on a sheet as seen when a woman standing behind it is shot, a scene where a boy is implied to be shot as he slumps to the ground while playing with a ball, and some black-and-white shots of war footage featuring some explosions, casualties lying on ground, etc.
There are also some scenes depicting bullying where the male protagonist was picked on by his peers in school when he was young.
